    Description

      When there are big number of partitions in a query this will result in a huge number of locks on ZooKeeper. Since the query object contains the whole query string this might cause serious memory pressure on the ZooKeeper services.

      It would be good to have the possibility to truncate the query strings that are written into the locks
