----------------------------------
Summary: DB Fetch processors do not support Expression Language
for Initial Max Value
Key: NIFI-5349
URL: https://issues.apache.org/jira/browse/NIFI-5349
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Reporter: Matt Burgess
As part of NIFI-2881, support for expression language was introduced for
many/most fields in the DB Fetch processors (GenerateTableFetch,
QueryDatabaseTable). However for the Initial Max Value properties (user-defined
properties of the form initial.maxvalue.<column>), the documentation is
inconsistent as to whether it supports EL, and if EL is present it is not
evaluated.
The DB Fetch processors should be updated to fully support (and correctly
document) the Initial Max Value capability. Note that the scope of EL
evaluation may differ between GenerateTableFetch and QueryDatabaseTable, as the
former accepts incoming flow files (via NIFI-2881) but the latter does not.
