----------------------------------
Thanks for your response [~jlowe].
{quote}Having a tidy ID to reference a set of ACLs would eliminate this
concern, but it would add some necessary indirection lookups on the reader
side.

Yes, doing a lookup in two tables at read time (regular entity table and
'domain' or 'ACLs' table) would be very slow in HBase. Hence we wanted to
denormalize it and store per entity.
But I understand the point about it being too cumbersome while creating each
entity. I will think over this a bit more and also discuss with
[~rohithsharma]and [~varun_saxena] and get back on this.
