Hi,
Over the last few days I have worked on a number of problems when is
sql_dbpool_enable is set a True. After a ton of debugging today I
referred to the Nova implementation (where it was originally taken from)
and discovered the following:
https://github.com/openstack/oslo-incubator/commit/02c12aade7a0c28c66cb45b54786c90c0ae8fb09
The problems that I was looking at were as follows:
1. When starting with a clean database and the various agents are
already running, multiple agent entries are created in the database
2. Once the entries are sorted an update of a agent entry causes an
exception [1]
I think that either we should drop the Grizzly support or mark it as
experimental. Any ideas or comments?
I the coming days I will try and update our H version to make use of the
common database interface.
Thanks
Gary
