> Currently datastream JDBC sink supports outputting data only to one table - 
> by having to provide SQL template, from which SimpleBatchStatementExecutor 
> creates PreparedStatement. Creating multiple sinks, each of which writes data 
> to one table is impractical for moderate to large number of tables - 
> relational databases don't usually tolerate large number of connections.
> I propose adding DynamicBatchStatementExecutor, which will additionally 
> require
> 1) provided mechanism to create SQL statements based on given object
> 2) cache for prepared statements
> 3) mechanism for determining which statement should be used for given object
