Modules

Modules can be chained together to create various storage workflows / setups.

Module	Description
ArtificialLatency	Adds a fixed latency to reads / writes for testing/benchmarking.
Cache	This contains a source, and a store of what data is contained in the cache. If the data is not in the cache for a read, a cache miss error is returned.
FilterRedundantWrites	This can filter out any redundant writes (Write data is same as source data), and can also cut large writes into smaller writes which only contains changed data.
Lockable	This can lock a source for some period.
Metrics	General metrics module to track read/write ops,bytes and latency
Nothing	Empty module - /dev/null
ReadDirtyTracker	Similar to a DirtyTracker, but only starts tracking writes to a block after it's been read ONCE.
ShardedStorage	This shards storage into multiple storage, which for example allows concurrent writes across shards.
Splitter	This allows the insertion of cache type sources. Any cache hit reads return immediately, whilst misses result in a read from the source, which then also gets written to any of the cache type sources.
CopyOnWrite	This allows a read-only source, and a cache. The cache is lazily filled as blocks are written.
