Enis Soztutar commented on HBASE-15879:
---------------------------------------
bq. The initial intention was to have this Key as an optimization for cells
with contiguous key but may be we should see if we can conceptualize this
inside a Cell itself.
Allright. One other idea we can pursue is to keep {{Cell}} as it is, so that we
keep the interface simple for the application/client side. And introduce
something like {{InternalCell}} which contains all advanced and implementation
level stuff we want the Cell interface to have optionally.

> Introduce an interface called Key and allow Cell implementations to implement
> this Key interface for cases like KeyValue, OffheapKeyValue and DBE cells
> (Except prefix tree) so that we can avoid copies when we deal with only Cells
> in case of block index creations (like ROOT, Bloom etc). Helps in reduction
> of garbage also.
