> 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.
