The following commit(s) were added to refs/heads/main by this push:
new 08ff54f5fb Add auto commit property to QueryDatabaseTable and
QueryDatabaseTable processors to allow disabling auto commit so PostgreSQL
Fetch Size will work
08ff54f5fb is described below
commit 08ff54f5fb712d01f372fd25a2d904d605e271ba
Author: Jim Steinebrey <jrsteineb...@gmail.com>
AuthorDate: Tue Mar 19 11:54:38 2024 -0400
Add auto commit property to QueryDatabaseTable and QueryDatabaseTable
processors to allow disabling auto commit so PostgreSQL Fetch Size will work
NIFI-1931 Add proper default value for auto commit (false) to
PostgreSQLDatabaseAdapter to allow FETCH_SIZE to be honored on reads.
NIFI-1931 Added customValidate code to check the auto commit property
setting against the db adapter's required auto commit setting and give
validation error message if they do not match.
NIFI-1931 Added automated test to check the Auto Commit customValidate
error message.
NIFI-1931 remove clearDefaultValue() because it is not needed since
required = false a;ready defaults it to null.
This closes #8534
