SharePoint 2010 is more than just SharePoint 2007 plus a bunch of new bullet points on the box. We didn’t just haphazardly build a bunch of new features, look back at the fertile seeds we planted, and muse about how “everything should work pretty well as libraries get large.” We built, and more importantly, tested all the features you’re reading about with scale in mind. We are setting new scale targets for 2010 that go above and beyond what we set in 2007. These numbers are not final yet, but we’re shooting for tens of millions of documents in a single library, depending on some specific parameters of your scenario.

When I throw out numbers like that, I’m not talking about just big, static libraries with content that just sits there. We want you to do crazy things with SharePoint 2010 like stuff a million document sets in a single document library with workflows running every which way, a hundred different retention policies firing off actions when you least expect them, and users uploading, tagging, and searching day in and day out. All the goodness of the SharePoint platform will be available to you whether you’re building a team site, a collaborative repository, a knowledge base, or a super large archive.

Like a plump, juicy sausage, much of the good stuff in SharePoint 2010 to give it delicious scalability are things that most people don’t need (or want) to know about. For the most part, scale just works. However, the chef (or information architect) is still a super important player. A well-planned repository is one that will have your users coming back for seconds and writing rave reviews; a poorly-planned one is one that will have them chugging Pepto-Bismol the next morning. Just because you can stuff a bunch of documents in a SharePoint 2010 library without your server igniting in flames the next day at doesn’t mean that you should without first thinking through how to best use the tools available to deliver an excellent experience to your end users.

So, even though scale in SharePoint 2010 just works, you’re not going to install the bits on day 1 and have a massive, searchable, beautiful content storefront on day 2. Guidance still matters, and believe me, we know it; this blog entry is just the beginning of the content we’re planning on delivering to help you on this front. I wouldn’t even call this blog entry guidance; it’s just a primer on the features and capabilities of SharePoint 2010 that you will grow to love if you’re passionate about scale at the library level – if you want to shove a whole bunch of documents in one place and have it be a great experience for both IT and your end users.

So what are these features and capabilities? Here are a few of the most important ones that I’m going to blog about now and in the near future:

1. We protect your database backend from dangerous queries. If you run a query against any database that requires it to scan through millions of items to find the ones you’re asking for, you’re going to balk at how long it ties up the server’s CPU. Quite frankly, SharePoint is not an exception. Even in SharePoint 2010, there is a class of user operations in certain scenarios that make unreasonable demands on the backend. For these operations, our strategy is to nip them in the bud before they’re executed, which keeps your high-demand servers healthy and responsive. Knowing when this throttling will kick in and planning for it is an important part of large list planning.
2. We give end-users tools to find content. When you have a sea of documents, the specific one you’re looking for can seem like a needle in a haystack. Structured metadata, easy tagging, metadata navigation, and built-in search refinement make this a less daunting task in SharePoint 2010 out of the box. This is an area we are particularly passionate about; after all, what good is a hugely scalable library if your end users hate it and can’t find what they’re looking for?
3. We help developers write excellent code. In SharePoint 2007, we didn’t give developers the right tools to write code that scaled well as the amount of content in your site grew. Even worse, it was pretty hard to tell why and when code was bad, and if your site was running slowly, which one out of your ten custom web parts was bringing things down. You had to “build around” SharePoint and do things “just so” to avoid this from happening. In SharePoint 2010, we give you a bunch of tools to make this story better.

Dangerous Queries

One challenge we’ve consistently seen customers run into when building large repositories on SharePoint 2007 is trouble with large containers. As the number of documents in any single container grows – either at the root of a library, or in a folder – bad things start to happen. For one, as your document to container ratio increases, it becomes harder and harder to find exactly what you’re looking for. More serious are the performance implications of large containers. Any of the out of the box ways of retrieving content from containers in SharePoint 2007 – like the All Documents view, the Explorer view, or a Content Query web part – would work, but they don’t scale very well. Loading All Documents in a library with a million items at the root would take a long time to finish. The big problem here is that you wouldn’t be the only one affected; all your friends running SharePoint sites on that same database server would experience things slowing to a crawl as well, as the database server dutifully iterated over those million documents to find the right ones.

Why does this happen? Any time you ask for content from SharePoint, you have to specify how it’s sorted – for example, the All Documents view in SharePoint 2007 asks for the top 100 results, sorted by filename. But items aren’t sorted by filename in the SharePoint content database – so, to bring you this view, SharePoint has to gather up all these million items, sort them, and finally display the 100 ones at the top of the sorted list. Imagine this as being like flipping through the residential section of a phonebook to find the first 100 addresses, sorted in alphabetical order. This would be a miserable task, because the telephone book isn’t sorted in this way – so in order to ensure your sorted list was accurate in the end, you’d have to look through the entire residential section, from start to finish, because after all, the last person listed in the phone book might live at 1000 Aardvark Lane.

Large Lists and Fallback Queries

The laws of physics are the same in SharePoint 2010 as they were in SharePoint 2007; if you run a query that needs to touch a very large number of items, you’re going to have to wait a long time, and so will everybody else. One prominent thing we did in SharePoint 2010 is to nip these queries in the bud before they get executed. To make a long story short (you can read the long story here), a farm administrator can set a threshold which defines the maximum number of items a single SharePoint query can touch. By default this threshold is 5,000. Any library with more items than this threshold is a large list.

Let’s go back to our example of the library with one million items at the root. Say you had that library in SharePoint 2007, and you upgraded to SharePoint Server 2010. First thing you’ll see upon navigating to this library will look something like this:

See the yellow bar above the list view? That’s a sign you have the Metadata Navigation and Filtering site feature turned on and it’s causing something magical to happen! When you load this view, SharePoint 2010 knows that you’re being greedy and asking it to scan through those million items. Since this query exceeds the maximum number of items a single query is allowed to scan (5,000) it doesn’t run the query. But who wants to stare at an empty list view? Instead of running this query as-is, SharePoint finagles it a bit and transforms it into a query that’s almost as good as the one you were asking for, but won’t make the database buckle under the pressure. In this case, we assume that it’s fairly likely that the document you’re looking for is one of the most recently created items in the library – so instead of scanning all one million items, we only scan the top 1,000 or so recently created documents, sort those by filename, and show them to you in the list view. This is what we call a simple fallback query: a query that doesn’t specify an index and asks for too many items in return, so instead of considering the entire list as being eligible for the query, SharePoint considers only the thousand or so most recently added items.

“Wait a second. You’re telling me that SharePoint throttles queries without asking me first? How on earth am I supposed to find anything in this crazy world of fallback queries and partial results?”

Let me assure you; this throttling business is a good thing. It’s a core ingredient in what makes SharePoint 2010 a resource for addressing your scale challenges. Gone are the sleepless nights where you toss and turn and worry about page faults on your database cluster resulting from Mack in Accounting stuffing 6,000 beer pong tournament photos in the root of a library in a forgotten team site in the dusty corners of your SharePoint deployment. The SharePoint 2010 feature set replaces this overarching concern with a set of well-scoped challenges; instead of worrying about every library that might get big, you get to plan for and craft experiences for the set of libraries that need to get big for business reasons.

I should mention really quickly that throttling is about more than just list views. There is a whole class of operations that involve iterating through all the documents in a list, or all the documents in a folder, that will get throttled (in other words, they will not execute) when the list or container is large. These operations include things like:

• Adding a column to a library
• Creating an index on a library
• Deleting a large folder in a library

Metadata Navigation – finding and working on content in large lists

Above is another screenshot from my million item library. This time, we’ve put a couple of SharePoint 2010 features to work. See that I have “demonstration scripts” selected in the left hand side in the tree view, and my list view is rendering without the yellow bar that’s telling me I’m only seeing newest results. That hierarchy of tags you see there represents a taxonomy, Item Type. I am browsing the documents in this library according to their Item Type; in the screenshot, I am filtering to show all documents with the value “demonstration scripts”. Here are the steps that I took to make this happen:

1. I created a taxonomy that describes my content. You can look forward to some posts from our very own Dan Kogan on this very topic in this very blog in the near future. There’s a lot to learn here. Not just any taxonomy will do here; it needs to be one that broadly divides my content up into evenly-sized buckets. For example, if I had 990,000 demonstration scripts, the query you see above would not get me anywhere. In that case, it wouldn’t make much sense to use Item Type as a piece of metadata and a navigation hierarchy for this library; I would need to find another, more divisive way to pivot the data.
2. I bound that taxonomy to a field in my library called Item Type. Think of a taxonomy field as a choice field on steroids. Instead of picking values out of a flat list, you pick them out of a tree.
3. I configured that field as a navigation hierarchy. Every library now has a Metadata Navigation and Filtering settings page where you can configure navigation hierarchies (the filters you see arranged in the tree view) and key filters (the additional filters that show up beneath the tree view)

In these three easy steps, I made “Item Type” a first class navigational pivot over the data. Instead of just staring at a partial list of content at the root, I can now browse with impunity by this virtual folder structure.

Here’s a couple of cool aspects of this feature that aren’t apparent from a single nifty screenshot:

1. Metadata navigation lets you slice and dice multiple ways. I might have a bunch of taxonomies on my library that classify content in different ways; for example, I might have a Products field, a Region field and a Competitors field, all bound to domain-specific taxonomies that classify the content along those dimensions. Depending on my current task, it might make more sense to filter by the Region field (for example, if I’m looking for the latest sales figures for the North America region). I get more filters than just my virtual folder; I can combine this filter with any number of key filters or list view column filters to drill down to just the content I want (for example, I want to see all demonstration scripts by the ECM team created after 2007).
2. Metadata navigation thinks about indices and large lists so you don’t have to. Hey, remember just a few minutes ago when we were talking about large lists, indices, and being throttled? Well, metadata navigation thinks a lot about indices and how to run queries the “right way” to make them perform well and prevent throttling from happening. For starters, all the fields you configure as navigation hierarchies and key filters get indexed, and the resulting queries are written in a way that ensures the best index is used to make the query succeed.

You aren’t immune from the laws of physics; if you ask for documents tagged with demonstration scripts and there are 10,000 demonstration scripts, we’re not going to be able to show you all of them. In this case, though, you get something better than a simple fallback; you get an indexed fallback, which means that instead of considering the entire list, the query considers only the items that match the indexed portion of your query.

Wrap-up

This article was just the first in my series of posts about architecting and building large lists filled with discoverable content. Here’s what you can expect over the next few weeks:

• A deep dive on metadata navigation, how it works, and some tips to getting the most out of it
• A discussion on how other features, like Search and the Content Query Web Part, fit into the equation, and how to configure their metadata filtering capabilities
• Some geeky developer tips on writing code that plays nicely with large lists

After that, I’ll be widening my scope a bit to talk about the overall knowledge management story in SharePoint 2010 – which is about more than just browsing for content in a library!

Lincoln DeMaris, Program Manager, ECM

Hi everyone, I am Quentin Christensen and I work on document and records management functionality for SharePoint. Electronic discovery (commonly referred to as eDiscovery) is an area we are supporting with new set of capabilities in SharePoint Server 2010. In case you are not familiar with eDiscovery, it is the process of finding, preserving, analyzing and producing content in electronic formats as required by litigation or investigations. eDiscovery is an important concern for all of our customers and given that SharePoint has grown to be an integral part of collaboration, document, and records management for many organizations, we recognize the need to support the eDiscovery process for SharePoint content.

Microsoft Office SharePoint Server 2007 included a hold feature that could be used for eDiscovery, but it was scoped to the Records Center site template. With SharePoint Server 2010 the eDiscovery capabilities have been greatly expanded to provide more functionality and the power to use these features across your entire SharePoint deployment.

In this post, I want to highlight three major improvements in SharePoint that support eDiscovery. You can:

• Manage holds and conduct eDiscovery searches on any site collection
• Use SharePoint Server Search or FAST Search for SharePoint out of box to search and process content
• Automatically copy eDiscovery search results to a separate repository for further analysis

Read on to learn how SharePoint Server 2010 can support your eDiscovery initiatives and provide you with the tools you need to manage holds, identify, and collect SharePoint content.

The eDiscovery Process

The Electronic Discovery Reference Model from EDRM (edrm.net) provides an overview of the different parts of the eDiscovery process:

SharePoint Sever 2010 addresses the Information Management, Identification, Preservation and Collection stages. While this blog post will focus mostly on the identification, preservation and collection components, SharePoint provides a rich Information Management platform for Collaboration, Social Computing, Document Management and Records Management.  This means that you can take a proactive approach to eDiscovery by putting a governance framework in place and using appropriate disposition policies to expire content. Managing content and deleting it when it is no longer needed will reduce the amount of content that must be indexed and searched, and collected for eDiscovery.  The result is that eDiscovery costs can be dramatically reduced, changing the problem from finding a needle in a hay stack to finding a needle in a hay bale. Ultimately, the key to achieving legal compliance for eDiscovery obligations is built upon a foundation of robust Information Management.

When an eDiscovery event occurs, such as a receipt of complaint, discovery, or notice of potential legal claim, the identification stage begins. Content that may be subject to eDiscovery must be identified and searches are conducted to find that content. That content needs to be preserved and at some point, the content will be collected.

The eDiscovery Features

Hold and eDiscovery

Hold and eDiscovery is a site level feature that can be activated on any site.

Activating this feature creates a new category in Site Settings that provides links to Holds and Hold Reports lists. There is also a page to discover and hold content that allows you to search for content and add it to a hold. Once the Hold and eDiscovery feature is activated you can create holds and add to hold any content in the site collection. By default only Site Collection administrators have access to the Hold and eDiscovery pages. To give other users permission, add them to the permissions list for the Hold Reports and Holds lists. This will also give access to the Discover and hold content page.

You can manually locate content in SharePoint and add it to a hold, or you can search for content and add the search results to a hold. With the Hold and eDiscovery feature you can create holds in the hold list and then manually add content to the relevant hold by clicking on Compliance Details from the drop down menu for individual items.

Then click on the link to Add/Remove from hold.

And you can select the relevant hold to add to or remove from.

By manually adding an item to hold you will block editing and deletion of that item until it is released from hold. You will notice that the document now has a lock icon showing that it cannot be edited or deleted.

Each night a report for each hold is generated by a timer job. If you need a hold report faster you can manually run the Hold Processing and Reporting timer job in Central Administration.

Search and Process

You can manually add items to hold on any site collection, which is great. But that doesn’t help you find the content you don’t already know about. What if you have a large amount of items you want to find and add to a hold? For that you can use the features on the Discover and hold content page, which is a settings page in Site Settings. From this page you can specify a search query and then preview the results. The configured search service (SharePoint Search Server or FAST Search for SharePoint) will automatically be used. You can then select the option to keep items on hold in place so they cannot be edited or deleted, or if you have configured a Content Organizer Send to location in Central Administration you can have content copied to another site and placed on hold. You may want to create a separate records center site for a particular hold to store all content related to that hold. The Content Organizer is a new SharePoint Server 2010 feature based on the Microsoft Office SharePoint Server 2007 Document Router with richer functionality to automatically classify content based on Content Type or metadata properties. Look for a future blog post covering the Content Organizer.

Holding content in place is recommended if you want to leave content in the location is was created with all the rich context that SharePoint provides, while blocking deletion and editing of content. Be aware that this will prevent users from modifying items. If you prefer users to continue editing documents, then use the copy to another location approach.

When searching and processing, the search will by default be scoped to the entire Site Collection and run with elevated permissions so all content can be discovered. The search can be scoped to specific sites and you can also preview search results before adding the results to a hold. Items can be placed on multiple holds and compliance details will show all of the holds that are applied to an item.

In summary, SharePoint Server 2010 contains key features that make it an essential aspect of your eDiscovery strategy. With the new SharePoint Server 2010 capabilities you can easily apply proper retention policies for all content and make it easier to discover content if an eDiscovery event occurs. eDiscovery often prescribes tight deadlines for production. SharePoint 2010 helps you find the right content and deliver it faster.

Quentin Christensen
Program Manager – Document and Records Management
Microsoft

Hi everyone. It’s Adam here again – this time I want to talk to you today about another key area of the content management world: Document Management (DM). Over the next few months, you’ll be hearing from several members of the engineering team about new DM features that help you get the most value out of your document corpus. We’ll also discuss how key early adopters of SharePoint 2010 used new DM features to solve the toughest information governance challenges.

Today, though, I’d like to spend time talking about what the team has learned about the document management space since SharePoint 2007 and take you on a journey through the key tenets that guided our DM vision this release.

Recap: Document Management in SharePoint 2007

SharePoint 2007 was the first release where SharePoint really broke out of its collaboration role and enabled customers to apply structure and management to their document libraries. A lot of the key DM infrastructure was established in that release: Check in/Check Out, Major/Minor Versioning, Per-Item Permissions, Content Types, Workflows, and the Recycle Bin are just a few examples. Of course, all of these features tightly integrated with the Office client applications such as Word, Excel, and PowerPoint to make it simple for end users to interact with the document repository (a core design tenet that carries through in 2010).

Features like these enabled customers to start creating high-value knowledge repositories on SharePoint 2007.

For 2010, we looked to build off of 2007’s gigantic success, and we rallied our designs around three key ideas:

Tenet #1: Manage the unmanaged

As we looked at how our customers were starting to use the 2007 system’s DM features, we noticed an interesting trend: These features were not just part of managed document repository deployments. Indeed, the traditional DM features were getting heavy usage in average collaborative team sites as well. Customers were using them to apply policy and structure as well as gather insights from what otherwise would have been fairly unmanaged places. SharePoint was being using to pull more and more typically unstructured silos into the ECM world.

This is a key insight that really drove our investments in SharePoint 2010. For instance, one of our key new features in SharePoint 2010 is the notion of a Document Set. You can think of a document set as a “folder on steroids.” It allows you to group related documents together so that they share metadata and have a common homepage, workflows, and archival process:

The Welcome Page of a document set is a customizable page that allows users to discover the content in the set, view and sync metadata between items in the set, and manage the set.

When it came time to design this feature, we knew people would want to use it to manage very structured and rigid official processes (e.g. a pharmaceutical company submitting forms to a regulatory agency). But equally important to us was that the feature can be used in a lightweight team site to manage most processes that requires multiple documents to be bound together (e.g. a team that just needs to put together a pitch book/sales proposal that includes a PowerPoint deck, a spreadsheet of costs, and a document that describes the sales pitch).

Enabling the document set feature to be used informally and easily is one way we are expanding the value of ECM in the minds of SharePoint end users.

Tenet #2: Social computing and enterprise metadata are game changers.

As we started to design out the DM feature set for this release, we quickly realized the power of metadata – both structured taxonomies as well as lightweight folksonomies (keywords) – as transformative forces in the document management space. A SharePoint 2010 document repository would need to take full advantage of both concepts.

There are two key principles that enable SharePoint 2010 users to take advantage of metadata. First is on the tagging side: it’s easy for a site to use enterprise wide content types and taxonomies and it’s also simple for a user to tag with them.

SharePoint 2010 offers consistent management of metadata that any SharePoint site can hook in to with virtually no effort. This allows the entire enterprise to be talking the same language. Tangibly, you can do things such as define the list of products you sell once and have that data available in any SharePoint site.

Note how the type-ahead functionality makes it easy for a user to pick a value from this folksonomy. Also note how the West Coast tag was automatically filled out for the user because it was set as the default value for all documents in this library.

The second key principle is how SharePoint takes advantage of these tags. For instance, a SharePoint 2010 document library can be configured to use metadata as a primary navigation pivot. You can think of metadata based navigation as a virtual folder structure that can be used to filter the items in the library:

Instead of navigating by traditional folders, a user filtered the library to the virtual folder that contains just sales materials about Contoso’s tent products.

It’s a virtuous cycle here: Easy metadata entry allows items to be tagged, which can drive navigation. And because users need the metadata to navigate the repository, this incentivizes them to tag the items!

Tenant #3: The browser as a powerful document management application.

SharePoint has always been used for many scenarios, but perhaps it’s known best for two things:

· A best of breed tool for creating web pages and sites

· A place to store, manage, and collaborate on documents

SharePoint 2010 makes a big bet that creating a knowledge management repository requires the merger of both of these worlds. The browser is increasingly becoming the key technology for information workers – both inside the corporate firewall and on the consumer front. Sure, people will always want to download documents to take with them – but they also want to use the browser to interact with the document and see a wealth of context about the document (e.g. metadata, related documents, wiki pages about the document’s topic).

It’s time for the industry to expect any document management system to also be great at creating pages or wikis that add context to the documents’ content. And any system that doesn’t is going to start looking antiquated.

SharePoint 2010 delivers on this vision in a few different ways. First, if you’ve installed the Office Web Apps (licensed as part of the Office 2010 suite), the default click for a document library can be configured to load Office documents in the browser:

Without ever leaving the browser, users can quickly view Office documents stored in SharePoint.

Second, we spent a lot of time this release thinking about how the web content management features can be used in document repositories. For instance, the ever popular Content Query web part can be used to roll up all the documents related to a particular topic:

A content steward might create a page about a particular topic (e.g. a new product). This page includes text about the product, marketing pictures, as well as roll ups of all the documents tagged with the product.

This vision allows you to combine two very powerful aspects of SharePoint into one solution to your organization’s knowledge discovery problem. It’s a merger of an enterprise wiki and a traditional enterprise document repository.

Wrapping up: A lot more to come!

I hope this post gives some context on where we are going with document management in SharePoint 2010 and beyond. Feature wise, we really only hit a few of the many DM features that make up SharePoint 2010 – stay tuned for future posts as we deep dive into a lot more! And feel free to leave comments about what you’d like us to blog about (especially if you’ve downloaded the Beta and given SharePoint 2010 a test drive already!)

Thanks for reading.
