Andrew Purtell commented on HBASE-7662:
---------------------------------------
Although we are prototyping this as an alternate implementation to HBASE-7661,
I think we will want to build this on HBASE-7661, so both inline and
out-of-line ACL storage options are available. (And which seems better for a
basket of common use cases as the default.)

> We can improve the performance of per-cell authorization if the read of the
> cell ACL, if any, is combined with the sequential read of the cell data
> already in progress. When tags are inlined with KVs in block encoding (see
> HBASE-7448, and more generally HBASE-7233), we can use them to carry cell
> ACLs instead of using out-of-line storage (HBASE-7661) for that purpose.
