Constant recalculation of CAgg on the same date

Hi Dear TSDB Team and all other people!

It is normal for CAgg not to recalculate data for the priod that has already been refreshed. But one bucket always refreshes when I call refresh_continuous_aggregate() and this bucket refers to 2017-01-01 month. Also hypertable does not contain new data (inserted or updated). If I refresh any other period for example from 2017-02-01 to 2018-01-01 then in console outputs expected message: continuous aggregate “monthly_cagg” is already up-to-date.

How can I determine why is this happining?

Best reagards,
Denis

Hello @LuxCore :wave:

Quick question: are you seeing any errors or warnings in your postgres or server logs please?

Also @LuxCore, what version of TimescaleDB are you using?

Unfortunately I can not see server logs.
