Please do a bit of background reading first before asking questions on the list. Big general questions such as yours are usually already answered multiple times over. See our refguide: http://hbase.apache.org/book.html For constraints, see http://hbase.apache.org/book.html#constraints Our limited ACID is also explained therein (The book points to this page: http://hbase.apache.org/acid-semantics.html). If you search the list for 'referential integrity', you will find the question was answered a few days ago already (none). Thanks, St.Ack
