v2.0.0 release

V2.0 Updates:

• ⚠️ Breaking Change - CosmosDB partition-related parameters are ignored. All containers use /id as the partition path now. Using an existing container with a different partition key path will result in exceptions. partitionKeyPath and partitionNumUsedByProvider are now ignored.

  The original design around partition use in the CosmosDB provider was influenced by experience with the older SQL partition paradigms. There was an effort to enable them for scalability, but keep them reasonable for managability. In reality, CosmosDB encourages the use of as many "logical" partitions as can be used so long as they make sense. The complexity of managing and scaling is all handled magically by CosmosDB.

  The most logical partition field for session state is the session ID. The CosmosDB provider has been updated to alway use "/id" as the partition key path with the full session ID as the partition value. Pre-existing containers that use a different partition key path (which is any that opted into using partitions previously) will need to migrate to a container that uses "/id" as the partition key path. The data is all still good - although, the old partition key path can be dropped when migrating. There is unfortunately no way to simply update the partition key path on an existing container right now. This blog post is a guide for migrating to a new container with the correct partition key path.

• ⚠️ Potential Breaking Change - Added managedHandler precondition to module configuration. The old in-box session module used this and it is a reasonable default for avoiding traffic jams. It can be removed from web.config if session is required for non-managed handlers as well.

• ⚠️ Action Required Sql provider repositoryType - This new setting provides a little more flexibility for repository configuration beyond a single boolean for in-memory optimized tables. Possible values are SqlServer|InMemory|InMemoryDurable|FrameworkCompat. Read about what each configuration is at our SqlSessionStateProviderAsync doc page.

  The mechanics of nuget package upgrade results in removing old elements and re-adding the boiler-plate elements in configuration. To restore In-Memory functionality, set 'repositoryType' to InMemory. To continue using an existing non-memory-optimized table without stored procedures, set 'RespositoryType' to FrameworkCompat. The recommendation is to update to the new table schema and use stored procedures with SqlServer, but this will ignore existing sessions in previously existing tables.

• Moved to use Microsoft.Data.SqlClient instead of old System.Data.SqlClient. This allows for more modern features such as Token Authorization.

• Added skipKeepAliveWhenUnused to all providers. This setting will skip the call to update expiration time on requests that did not read or write session state. This is setting is used at the module level, and is thus exists on all providers. The default is "false" to maintain compatibility. But certain applications (like MVC) where there can be an abundance of requests processed that never even look at session state could benefit from setting this to "true" to reduce the use of and contention within the session state store. Setting this to "true" does mean that a session needs to be used (not necessarily updated, but at least requested/queried) to stay alive.

• The Sql provider's useInMemoryTable is deprecated. It will continue to be respected in the absence of repositoryType, but is overridden by that setting if given.

• Sql provider sessionTableName - A new setting that allows users to target a specific table in their database rather than being forced to use the default table names.

• CosmosDB collectionId is now containerId in keeping with the updated terminology from the CosmosDB offering. Please use the updated parameter name when configuring your provider. (The old name will continue to work just the same.)

• Added CosmosDB consistencyLevel to allow using a different Consistency Level with the CosmosClient.

• CosmosDB connectionProtocol is obsolete. It will not cause errors to have it in configuration, but it is ignored. The current CosmosDB SDK chooses the protocol based on connection mode.

v1.1.0 CosmosDB release
