Regular expressions not working

[MaartenMol]

When running a query in Grafana with expressions like name=~"test|123", no data is shown.

I don't know if this is normal or a bug?

Hi @MaartenMol, can you please provide more insights for this request? I.e. what CrateDB version and setup, which Prometheus and grafana versions and setup you are using? What is the data you ingest from Prometheus and what is the schema in CrateDB you want to query?

Dear Maarten,

apologies for replying so late. The whole ecosystem has advanced since you've created this issue, so I am assuming this is not an issue anymore, and it will be safe to close this. Please let me know how to reproduce the error otherwise, and I will be happy to look into it.

With kind regards,
Andreas.

Dear Maarten,

hi again about this topic, and a happy new year. Even if you might no longer be interested (please tell us), we wanted to tell you that version 0.5.0 has been released today, and we are just now looking at your report again.

On this matter, we can only discover a225ebb and GH-27 making changes to the relevant code. By implementing prompb.LabelMatcher_RE and prompb.LabelMatcher_NRE, we think regular expressions should work in general.

Maybe it is specific to your expression, which includes the OR operator in form of the pipe symbol |?

With kind regards,
Andreas.

Hi again,

we added corresponding integration tests to verify a few variants of query expressions, and haven't been able to observe any problems so far.

• Tests: Integration tests to verify query expressions end-to-end #115

Thus, I am closing this. Please feel free to re-open if you think the flaw is still there.

With kind regards,
Andreas.
