[jira] [Created] (IGNITE-19558) Sql. Use statistics snapshot per sql request.

Evgeny Stanilovsky created IGNITE-19558:
-------------------------------------------

             Summary: Sql. Use statistics snapshot per sql request.
                 Key: IGNITE-19558
                 URL: https://issues.apache.org/jira/browse/IGNITE-19558
             Project: Ignite
          Issue Type: Bug
          Components: sql
    Affects Versions: 3.0.0-beta1
            Reporter: Evgeny Stanilovsky


Now possible situation when in scope of one sql request planning it`s possible to obtain different table row count, check: StatisticsImpl#getRowCount, this can lead to erroneous or not optimal plan. Seems we need smth. like statistics snapshot for such a case.

starting points:

{noformat}
IgniteTableImpl.StatisticsImpl
{noformat}
