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

             Summary: Query history statistics API
                 Key: IGNITE-10754
                 URL: https://issues.apache.org/jira/browse/IGNITE-10754
             Project: Ignite
          Issue Type: Task
          Components: sql
            Reporter: Yury Gerzhedovich
            Assignee: Yury Gerzhedovich


As of now we have query statistics (*_org.apache.ignite.IgniteCache#queryMetrics_*) , but
have few issues.
1) Duration execution it just time between start execution and return cursor to client and
doesn't include all life time of query.
2) It doesn't know about multistatement queries. Such queries participate in statistics as
single query without splitting.
3) API to access the statistics expose as depend on cache, however query don't have such dependency.
 
Need to create parallel similar realization as we already have.
Use new infrastructure of tracking running queries developed under IGNITE-10621 and update
statistics on unregister phase.
Expose API on upper level then it placed now. Right place will be written later.
 
Old API will be marked as deprecated.
