> Often DataFlows contain many processors which deal with database - select,
> update or delete different data in different tables.
> Yet database is same and connection pooling helps to speed up connecting to
> database (open connection is fairly expensive). Also configuration must be
> done only in one place.
> Database Connection Pooling Controller Service helps to solve this in
> consistent way.
