[jira] [Created] (IGNITE-14651) Node with persistence starts up slowly if configured with significant archive (on a slow disk)

----------------------------------------

             Summary: Node with persistence starts up slowly if configured with significant archive (on a slow disk)
                 Key: IGNITE-14651
                 URL: https://issues.apache.org/jira/browse/IGNITE-14651
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.10
            Reporter: Sergey Chugunov


Improvement implemented in IGNITE-13052 moved calculating GroupStates (needed for historical rebalancing) to startup phase for optimization purposes.

This lead to significant increase of startup time for some set ups with significant WAL archive configured on a slow disk.

We need to consider options to optimize calculating rebalancing data structures further, e.g. by processing CP history in parallel or by calculating structures asynchronously and waiting for it when it really needed (instead of synchronously awaiting on startup).
