Distributed in-memory cache - Velocity

Distributed in-memory cache from Microsoft at last!

Velocity is the code name for this distributed in-memory cache with the following features:

  • Distributed in-memory cache
  • A cluster of cache hosts provides fault tolerance
  • Supports optimistic as well pessimistic locking of cached objects
  • Manage the memory footprint through cache expiration (TTL) and LRU based eviction
  • Supports named caches and searchable regions
  • Client side cache using cache-aside pattern
  • ASP.NET session synchronization
  • Uses TCP/IP between the cache client and the cache cluster
  • The cache host is a Windows service running on a physical server. The host service can run on the same server as the cache client (e.g. web farm) or on a separate physical server with which the cache client (web server or other application client) can communicate with.

The above are a few aspects of Velocity as in the first CTP1 bits. The above may change during subsequent iterations of the product.
