> Project: Sentry
> Issue Type: Sub-task
> Components: Sentry
> Affects Versions: 2.0.0
> Reporter: Alexander Kolbasov
> Assignee: Na Li
> Fix For: 2.0.0

>
> Looking at the latest stress runs, we noticed that some of the transactions
> could fail to commit to the database (with Duplicate key exception) after
> exhausting all the retries.
> This problem has become more evident if we have more number of clients
> connecting to Sentry to issue the permission updates. Was able to reproduce
> consistently with 15 clients doing 100 operations each.
> In the past we introduced exponential backoff (SENTRY-1821) so as part of
> test run increased the defaults to 750ms sleep and 20 retries. But even after
> this, the cluster still shows up the transaction failures. This change also
> increases the latency of every transaction in sentry.
> We need to revisit this and come up with a better way to solve this problem.
