title: Nifi QueryDatabaseTable processor leads to data loss running as a Docker Image
body: <p>While running the querydatabase processor in NiFi some records are getting lost. </p>
  
  <p>I am try to pull the data from Oracle DB and the maximum-column-value is a created Date of the date datatype. There is no timestamp attached to that(23-JUN-18) . While triggering the job every 5 mins to achieve near-real time ingestion some records are getting lost. I am not sure whether this is happening due to time stamp not present in the table OR whether this can be a synchronization issue like while querying the DB if new records got inserted</p>
