Summary: External Materialization MySQL can't swap primary and stage table in xa transaction
Key: TEIID-4579
URL: https://issues.jboss.org/browse/TEIID-4579
Project: Teiid
Issue Type: Bug
Components: Server
Affects Versions: 8.12.7.6_3
Reporter: Jan Stastny
Assignee: Steven Hawkins
When using MySQL 5.5 as materialization target (primary and stage table are placed there) and on server side the mysql datasource is configured as xa-datasource, problem with transaction scope and status appears.
The cause of this issue is, that in my "teiid_rel:MATVIEW_AFTER_LOAD_SCRIPT" I try to swap primary and stage materialization tables by using third swap table:
{code:sql}
exec Source.native(''ALTER TABLE DV_MATVIEWS_MAT_VIEW_STAGE RENAME TO DV_MATVIEWS_MAT_VIEW_TEMP'');
exec Source.native(''ALTER TABLE DV_MATVIEWS_MAT_VIEW RENAME TO DV_MATVIEWS_MAT_VIEW_STAGE'');
exec Source.native(''ALTER TABLE DV_MATVIEWS_MAT_VIEW_TEMP RENAME TO DV_MATVIEWS_MAT_VIEW'');
{code}
but there is a limitation of ALTER TABLE commands which results in implicit commit:
https://dev.mysql.com/doc/refman/5.5/en/implicit-commit.html
Eventually the first of the three ALTER commands succeeds, but the second fails, thus I end up with no DV_MATVIEWS_MAT_VIEW_STAGE table, as it was previously renamed to DV_MATVIEWS_MAT_VIEW_TEMP. This particular problem could be resolved by TEIID-4240 I believe.
The stacktrace of the issue:
