Hi,
I'd like to raise a proposal to add Connector Upgrade Drain and Flow
Definition Persistence to the projects evolving connector framework.
The goal is to increase safety and reliability when connectors are
upgraded from one version to the next. This proposal includes creating
a persisted version of the connector's active flow to allow it to
operate prior to the upgrade. The proposal also adds a hook that allows
the connector developer to take specific actions prior to changing the
connector's flow during an upgrade. I've included details in a JIRA [1]
for review by the community. As a committer I am request a PMC member
to sponsor this and raise a vote. Thank you for your consideration!
Sincerely,
Bob Paulin
