Keith Turner commented on GORA-216:
-----------------------------------
bq. return a Persistent instance whenever the row exists and return null when
the row does not exists.
So this is a change in behavior from previously released version of Gora? If
so I think its tricky for users, if they write their code expecting a certain
behavior and then the behavior changes while the interface stays the same.
Also, its more expensive to do this. In the case of Accumulo the table scan
returns nothing because it was filtered on a nonexistant column. So every time
I get nothing back for a scan I would need to do a second scan with no column
filtering to see if the row exist. Or I always do the first scan w/ no column
filtering. Is it the same w/ HBase?
