Enis Soztutar commented on HBASE-14983:
---------------------------------------
Trailers do not go into block cache, so probably we don't need it. Not sure
FileInfo blocks are put to block cache or not.
Should Data and EncodedData be only a single metric? Most of the users will
look at the combined values I think.
Otherwise looks good. Are we gonna add percentages as well? What about caching
vs non-caching reads?
> Create metrics for per block type hit/miss ratios
