---------------------------------
Summary: AbstractDatabaseFetchProcessor Timestamp Precision can
causes perpetual reads
Key: NIFI-2518
URL: https://issues.apache.org/jira/browse/NIFI-2518
Project: Apache NiFi
Issue Type: Bug
Reporter: Jeremy Dyer
Assignee: Jeremy Dyer
Fix For: 1.0.0, 0.7.0
The AbstractDatabaseFetchProcessor.java component has a toString method in the
return of input database timestamps. In that, if the precision is stored lower
than milliseconds, it can cause fetch issues. So, in the QueryDatabaseTable
processor for example, the incremental fetch when the precision is at
TimeStamp(6) versus TimeStamp(3) will lead to perpetual reads. A potential work
around is for the source database to either refrain from using precision beyond
TS(3) or to leverage a view for NiFi to consume from.
