[jira] [Created] (IGNITE-26488) Introduce configuration to override CREATE TABLE defaults for data staleness configuration

Konstantin Orlov created IGNITE-26488:
-----------------------------------------

             Summary: Introduce configuration to override CREATE TABLE defaults for data staleness configuration
                 Key: IGNITE-26488
                 URL: https://issues.apache.org/jira/browse/IGNITE-26488
             Project: Ignite
          Issue Type: Improvement
          Components: sql ai3
            Reporter: Konstantin Orlov


To improve UX, it's proposed to introduce two more distributed configuration properties, so user can specify cluster-wide defaults for introduced staleness configuration attributes:

{code}
sql.createTable.defaultStaleRowsFraction = 0.2 (default) // fraction of table partition required to be modified to trigger statistics recollection, i.e. currentSize * staleRowsFraction to compute actual number of rows required

sql.createTable.defaultMinStaleRowsCount = 500 (default) // minimal number of updates to a table partition required to trigger statistics recollection
{code}
