> Key: IGNITE-2820
> URL: https://issues.apache.org/jira/browse/IGNITE-2820
> Project: Ignite
> Issue Type: Task
> Components: IGFS
> Affects Versions: 1.5.0.final
> Reporter: Vladimir Ozerov
> Priority: Critical
> Fix For: 1.7
>
>
> *Problem*
> Sometimes we have to create new entries during some operation on metadata. If
> we do not lock this ID along with other participating IDs right after TX
> start, subsequent cache operation on this ID will result in network calls to
> block this key on other nodes.
> *Solution*
> Create potentially new key before entering TX and lock it with other keys.
> This should decrease number of network calls.
