[jira] [Created] (IGNITE-17732) Avoid locking indexes in transaction

Vladislav Pyatkov created IGNITE-17732:
------------------------------------------

             Summary: Avoid locking indexes in transaction
                 Key: IGNITE-17732
                 URL: https://issues.apache.org/jira/browse/IGNITE-17732
             Project: Ignite
          Issue Type: Improvement
            Reporter: Vladislav Pyatkov


The transaction protocol requires lock all indexes (now it is a pk) in the same manner as it happens for data (locks on {_}RowIds{_}). But lock manager cannot resolve all problems in his case (in particular, waiter for _RowId_ does not create when the lock on index have not got).

As a temporary workaround for this disadvantage, supposed:
 # Create a NAL (Not a lock) lock mode, which is compatible for all another mode
 # All lock modes on PK should convert to NAL
