[infinispan-dev] OGM, Hot Rod and Grouping API

[Emmanuel Bernard]

We expect the same semantic as a RDBMS in READ_COMMITTED. getGroup() would be equivalent to a select * from ASSOC_TABLE where owner_id = 2. Phantom reads would be acceptable.

Does that answer your question? Because I’m not sure what you mean by the key being attached to the Tx.
