stack commented on HBASE-20894:
-------------------------------
Added a suggestion (See
[^0001-Write-the-CacheableDeserializerIdManager-index-into-.patch] ). It is
incomplete. Missing is some serialization juggling (TODO). Patch removes an
indirection that we have in naming BucketEntry deserializers. If we are
breaking serialization -- i.e. moving from one serialization type to another --
this is an opportunity for simplifying this bit of cryptic code. Perhaps
integrate this patch? I'll finish it up if wanted (This suggestion comes of an
innocent [~mdrob] question asking what is UniqueIndexMap for?).
