DynamoDBSessionManager

Overview

The DynamoDBSessionManager class represents a session manager that stores session data in the DynamoDB NoSQL database.

Sessions are stored out-of-process and are able to survive a service restart. Session data can be shared between several services of the same type thus allowing to implement load balancing mechanisms like Round Robin etc.

There are two things one should consider before using the DynamoDBSessionManager component to store session data:

  1. For obvoius reasons, session access performance is considerably lower for the DynamoDBSessionManager compared to the In-Memory Session Manager, because accessing data stored in the DynamoDB takes much more time than accessing a session object stored in memory.

  2. Not all data types can be stored in a DynamoDB session. Supported types are:

  3. Primitive values:
    • Binary ** Boolean ** Byte ** Currency ** DateTime ** Decimal ** Double ** Guid ** Int8 ** Int16 ** Int32 ** Int64 ** String
  4. Classes inherited from the ComplexType class. In this case methods ComplexType and ComplexType are used to serialize/deserialize data
  5. All .NET classes marked with the Serializable attribute. In this case .NET serialization facility will be used
  6. Arrays of types listed above

The DynamoDBSessionManager class requires an active Amazon Web Services subscription. While it is possible to use the DynamoDBSessionManager session manager with local DynamoDB emulator it is strongly not recommended for production use (as the DynamoDB Local Test Tool is a development tool, not a production-use database).

The DynamoDBSessionManager class supports 2 different ways of setting up the DynamoDB access:

Via providing AWS access key and AWS secret key via properties of the DynamoDBSessionManager instance.

Via providing AWS access key and AWS secret key via application configuration file:

<?xml version="1.0" encoding="utf-8" ?>

Also either RegionName or ServiceURL properties should be set.

To store session data DynamoDBSessionManager class uses DynamoDB table Sessions where should be defined HASH key of type String. Check the CreateStorageIfNeeded property definition to find out how to let the DynamoDBSessionManager instance to automatically create the session storage table if needed.

Note: The Initialize method should be called once the properties of the session manager instance are set. This method establishes connection to the DynamoDB services and recrreates the session storage table if needed.
