Implementing List Governance With Performance Consideration In SharePoint 2010 – Part 2

Managed Metadata – With Managed metadata you will have a new set of features that add information to the architecture of the SharePoint Server. The managed metadata will offer a shared service known as the managed metadata service. This can be used for storing term sets and it can also be used to deploy the SharePoint environment. Elements of this feature include terms that can support both deep and flat hierarchies, managing metadata column type, and term sets that are open or restricted.

The use of managed metadata columns and terms that are set for organizing content allow you to use the features of content querying. Both metadata and the Content Query Web Part navigation help a user to find content. With managed metadata there is also the regular search queries available. This allows for keywords to be added to classified documents. It also allows for managed metadata to be used in the search panel.

Limits and Throttles – Through SharePoint Server 2010 there are various limits that can be configured for farm performance to be maintained. The Web application level is configured with limits and throttles. They were added to offer more operations for individual users or processes. However, they don’t affect the overall farm performance. The list view threshold is a limit that stops queries from affecting a given number of list items.

Compound Index – One of the important elements of large lists is the use of indexes. With SharePoint Server you will be able to create a compound index. These are useful for queries that will be performed on two columns versus just one. When you only have one, it may not be selective enough. A compound index allows for utilization of various views but they can still be accessed with metadata navigation. A throttle condition will occur when they metadata attempts to retry and then indexing is based on the various filters that apply.

Developer Dashboard – With the developer dashboard display there is a diagnostic detail for each page that loads. The default can be left on if you like. The developer will allow you to get information about load times, errors, and database queries. The metadata navigation is visible in the developer dashboard.

This means that large lists and throttle conditions are for the list of indexes. They are used to retry and for partial results that can appear in the operation tree. This is on the left side. The SQL Server queries are found on the right side. The developer dashboard allows for debugging the custom Web Parts and queries.

Content Iterator – The content Iterator is developed for API and it simplifies the writing code for large lists. This is important when there is a new list view limit. The content iterator offers a way for retrieving content and performing operations on small sets. This is different than performing operations on the entire set as before. The result is that you don’t have to worry about exceeding the threshold for a give list view.

Remote BLOB Storage – The SharePoint default results in files stored as Binary Large Objects (BLOB). This is in the SQL Server database. There is a large amount of content found in the database. BLOB storage also allows for more to be stored outside of the SQL Server. This allows for less cost to be involved with storing the options. At the same time this reduces the content database size. Remote BLOB storage is a library API set for the add on pack with the SQL Server 2008. There can be a 3rd party remote BLOB storage provider required for the remote BLOB storage API.
