James Taylor updated PHOENIX-2909:
----------------------------------
Description:
We could potentially recognize updates to the same column in a SQL statement
and compile them into either a check and put or increment call.
For example, the following could use increment or a get/put under row lock to
perform the row update atomically
{code}
UPSERT INTO my_table(pk1, pk2, counter) SELECT pk1, pk2, counter + 1 FROM
my_table;
{code}
was:We could potentially recognize updates to the same column in a SQL
statement and compile them into either a check and put or increment call.
> Support compilation to atomic increment for non transactional tables
