> Better fail-over on commit/begin
> --------------------------------
>
> Key: SEQUOIA-228
> URL: https://forge.continuent.org/jira/browse/SEQUOIA-228
> Project: Sequoia
> Type: Improvement
> Components: JDBC Driver, Core
> Versions: Sequoia 2.1, Version 2.2, Sequoia 2.3, Sequoia 2.4
> Reporter: Olivier Fambon
> Fix For: Sequoia 2.4
>
> Original Estimate: 2 days
> Remaining: 2 days
>
> In JDBC, connection.commit() performs both commit and begin.
> In the situation where the controller that handles the connection/transaction
> goes down just after the commit but before the begin, the commit suceedes
> but an error is reported to the user, and no begin is performed (?).
> This can be improved by:
> - splitting the 'commit' protocol message in two parts: 1/ commit, 2/ begin
> - handling the potential failure of the second message by failing-over to
> another controller
