>             Project: Ignite
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.8

> 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. This along with separate thread pool for SQL queries (see IGNITE-4105) should resolve the issue..
