VictoriaMetrics calculates `increase(m[d])` at timestamp `t` as `vLast - vPrev` where `vLast` is the last raw sample value on the time range `(t-d ... t]` and `vPrev` is the last...

@jelmd , could you export the raw data in [JSON line format](https://docs.victoriametrics.com/#how-to-export-data-in-json-line-format) instead of CSV, since [CSV format](https://docs.victoriametrics.com/#how-to-export-csv-data) may miss some important labels and millisecond precision for the timestamps stored...

> I guess the rfa.timestamps and rfa.values were produced with a wrong sample rate `rfa.timestamps` and `rfa.values` contain **raw** samples stored in VictoriaMetrics on the time range `(t-d ... t]`...

The bugfix for `rate()` with short lookbehind window in square brackets has been included in [v1.85.3 release](https://github.com/VictoriaMetrics/VictoriaMetrics/releases). Closing the issue as fixed.

`vmstorage` drops some in-memory caches when it rotates `indexdb` partitions, since these caches must contain data related to the current `indexdb` partition, which becomes empty after the rotation. The `indexdb`...

The commit 8e9822bc7f0f0591555be4faa76dd5af431e2000 optimizes the hostspot at `TSID.Less()` function. @petanne , could you try building `vmstorage` from this commit according to [these instructions](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#building-from-sources) and verifying whether the `TSID.Less()` call is...

@petanne , could you try building `vmstorage` from the commit fbeebe4869892a9dd3c684da5fbaa0a6c511a651 and verify whether this helps resolving the issue? See [build instructions](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html#building-from-sources). It is safe running `vmstorage` from this commit...

> Where can I learn partition and block? What happens during a search request in vmstorage? Please take a look at https://docs.victoriametrics.com/#storage and https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3268#issuecomment-1291249751
