Valentin Kulichenko updated IGNITE-6575:
----------------------------------------
Issue Type: Improvement (was: Bug)
> IgniteCache#get can return stale value when executed on backup
> --------------------------------------------------------------
>
> Key: IGNITE-6575
> URL: https://issues.apache.org/jira/browse/IGNITE-6575
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: 2.2
> Reporter: Valentin Kulichenko
>
> If write sync mode is {{PRIMARY_SYNC}} and {{readFromBackup=true}} (both
> values are defaults), calling {{get}} right after {{put}} for the same key in
> the same thread can return stale value. This happens because even local
> backup is updated asynchronously.
> This is very confusing behavior for a user, would be good to make sure to
> update local backup synchronously even in {{PRIMARY_SYNC}} mode.
> More details here:
