----------------------------------

             Summary: QueryDatabaseTable processor; setFetchSize not working 
for postgres driver causing out of memory
                 Key: NIFI-1931
                 URL: https://issues.apache.org/jira/browse/NIFI-1931
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 0.6.1
            Reporter: Paul Bormans


With NIFI-1691 the ability to specify the fetch size is added. However for 
postgres driver (or at least for postgresql-9.4.1208.jre6.jar) this seems not 
to be working since after some time out of memory is reported in the logs.

See https://jdbc.postgresql.org/documentation/head/query.html also for some 
constraints; like auto commit needs to be set to False.
