If a query returns an unexpected result or takes longer than expected to process, this page will help you troubleshoot the issue.
Correctness Issues
If your queries return unexpected results, there are several possibilities:
- You’ve encountered a known limitation, UX surprise or other problem with SQL semantics. Feel free to leave a comment on the existing issue indicating that you’ve encountered a problem as well.
- Your application has a bug. It's always worthwhile to check and double-check your application’s logic before filing an issue. That said, you can always reach out for support.
- CockroachDB has a bug. Please file an issue.
Performance Issues
If queries are taking longer than expected to process, there are a few things you can check into:
Review your deployment's monitoring. General network latency or partitioning events can affect query response times.
If you're still unable to determine why the query executes slowly, please file an issue.
bad connection & closed Responses
If you receive a response of bad connection or closed, this normally indicates that the node you connected to died. You can check this by connecting to another node in the cluster and running cockroach node status.
Once you find the downed node, you can check its logs (stored in cockroach-data/logs by default).
Because this kind of behavior is entirely unexpected, you should file an issue.
