             Summary: SQL: Statement cache can cause memory leak
                 Key: IGNITE-4578
                 URL: https://issues.apache.org/jira/browse/IGNITE-4578
             Project: Ignite
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.8
            Reporter: Andrew Mashenkov


We have prepared statement cache in IgniteH2Indexing declared as Map<Thread, 
StatementCache>.
This can cause memory leak if threads will die unexpetedly.

We should declare StatementCache as ThreadLocal field along with separate 
thread pool for SQL queries, see IGNITE-4105.
