Since firefly, ceph can support cache tiering.
Cache tiering: support for creating ‘cache pools’ that store hot, recently
accessed objects with automatic demotion of colder data to a base tier.
Typically the cache pool is backed by faster storage devices like SSDs.
I'm testing cache tiering, and everything goes well.
But rados -h shows that:
CACHE POOLS: (for testing/development only)
cache-flush <obj-name> flush cache pool object (blocking)
cache-try-flush <obj-name> flush cache pool object (non-blocking)
cache-evict <obj-name> evict cache pool object
cache-flush-evict-all flush+evict all objects
cache-try-flush-evict-all try-flush+evict all objects
ceph version 0.80.7 (6c0127fcb58008793d3c8b62d925bc91963672a3)
Is cache tiering production ready?
Thanks a lot!
