> 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.
