> Project: Apache Lens
> Issue Type: Improvement
> Components: driver-jdbc
> Affects Versions: 2.0
> Reporter: Amareshwari Sriramadasu

> Priority: Critical
> Fix For: 2.1

>
> Right now, ColumnarSQLRewriter.rewrite is synchronized because rewriter is
> cached in JDBCDriver and it uses all class level variables to keep query
> rewriting state.
> Having this synchronized will make other queries wait for rewrite. We should
> have separate rewriter created for each query or move the state out of
> ColumnarSQLRewriter sothat it need not be synchronized.
