Andrew Wang commented on HDFS-5851:
-----------------------------------
bq. Does CCM support block-level caching or is it just cache all blocks in a
file?
Right now, the user APIs are all in terms of files, but the backend could do
single blocks pretty easily. We didn't add block-level cache directives because
we feel automatic cache eviction is a better solution (and could operate at the
block or subblock level).
Looking forward to the design doc! Feel free to ping us even with preliminary
usecases/ideas.
