-----------------------------------
> MVCC TX: Handling transactions from multiple threads in jdbc requests handler.
> ------------------------------------------------------------------------------
>
> Key: IGNITE-9484
> URL: https://issues.apache.org/jira/browse/IGNITE-9484
> Project: Ignite
> Issue Type: Task
> Components: jdbc, mvcc
> Reporter: Roman Kondakov
> Priority: Major
>
> Currently JDBC/ODBC requests are handled in NioWorker threads; that means
> what sessions may be rebalanced between nio threads which makes impossible to
> associate a NearTransaction with caller thread.
> There are two possible solutions:
> # To process client messages like regular grid ones in separate thread pool
> in thread-per-connection basis
> # Implement Suspend/Resume functionality for pessimistic transactions like
> it was done for optimistic ones (only pessimistic transactions are supported
> by mvcc-enabled caches)
