-------------------------------------
Assignee: (was: Alexey Goncharuk)
> Optimize transaction prepare step when store is enabled
> -------------------------------------------------------
>
> Key: IGNITE-1553
> URL: https://issues.apache.org/jira/browse/IGNITE-1553
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: ignite-1.4
> Reporter: Alexey Goncharuk
> Labels: important
>
> Currently entries are enlisted in a database transaction after grid
> transaction is in PREPARED state. We can do this in parallel in the following
> fashion (pseudo-code):
> {code}
> fut = tx.prepareAsync();
> db.write(tx.writes());
> fut.get();
> try {
> db.commit();
>
> tx.commit();
> }
> catch (Exception e) {
> tx.rollback();
> }
> {code}
> If this approach is applied, we should be able to reduce latency for
> transactions when write-through is enabled.
