> Key: IGNITE-26069
> URL: https://issues.apache.org/jira/browse/IGNITE-26069
> Project: Ignite
> Issue Type: Improvement
> Components: sql ai3
> Reporter: Konstantin Orlov
> Assignee: Evgeny Stanilovsky
> Priority: Major
> Labels: ignite-3
>
> Currently, statistic manager recollects statistics on demand. This causes a
> problem when plan is prepared shortly after bulk data loading: it's prepared
> with outdated statistics and no recollection is triggered since no one is
> touching them.
> To address the issue, let's switch to recollection on data stale. To do this,
> let's collect staleness timestamp prepared in IGNITE-26067, and if staleness
> is detected, recollect statistics for related table.
