krad	d755c62f92	Persistent Read Cache (5) Volatile cache tier implementation ... Summary: This provides provides an implementation of PersistentCacheTier that is specialized for RAM. This tier does not persist data though. Why do we need this tier ? This is ideal as tier 0. This tier can host data that is too hot. Why can't we use Cache variants ? Yes you can use them instead. This tier can potentially outperform BlockCache in RAW mode by virtue of compression and compressed cache in block cache doesn't seem very popular. Potentially this tier can be modified to under stand the disadvantage of the tier below and retain data that the tier below is bad at handling (for example index and bloom data that is huge in size) Test Plan: Run unit tests added Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D57069	9 years ago

krad	3070ed9021	Persistent Read Cache (4) Interface definitions ... Summary: This diff provides the basic interface definitions of persistent read cache system PersistentCacheOptions captures the persistent read cache options used to configure and control the system PersistentCacheTier provides the basic building block for constructing tiered cache PersistentTieredCache provides a logical abstraction of tiers of cache layered over one another Test Plan: Compile Reviewers: sdong Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D57051	9 years ago
