Andrew Kyle Purtell commented on HBASE-25187:
---------------------------------------------
Moved out of 2.4.
There are about 60 hours remaining before the 2.4.0RC0 is unblocked, if you
want to get this in before then.
> Improve SizeCachedKV variants initialization

> Currently in SizeCachedKV we get the rowlength and Key length from the
> buffers. This can be optimized because we can pass the keylen and row len
> while actually creating the cell while reading the cell from the block. Some
> times we see that the SizeCachedKV takes the max width in a flame graph -
> considering the fact we also do a sanity check on the created KV.
