Description
Gunnar Hillert opened INT-2676 and commented
Investigate the following question:
-
Should we possible do DB specific SQL queries? E.g. for MySQL and Oracle do "select ... for update" helping prevent duplicate reads.
-
Should we consider DB specific Message Store implementations? Microsoft SQL Server has "Query Notifications" (not supported for JDBC?)

Oracle has Database Change Notifications

and PostgreSQL may also have respective support.
Affects: 2.1.3
