Elliott Clark commented on HBASE-14983:
---------------------------------------
bq.Trailers do not go into block cache, so probably we don't need it.
My thought is to see what is being read so that figuring out what needs to go
in the block cache should be better.
bq.Should Data and EncodedData be only a single metric?
Probably, let me get that.
> Create metrics for per block type hit/miss ratios
