This reverts the following commits: -e0e16a2d36-2ce02a7fe6The reason for revert: the updated logic breaks assumptions made when fixing https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2698 . For example, if a time series stop receiving new samples during the first day after the indexdb rotation, there are chances that the time series won't be registered in the new indexdb. This is OK until the next indexdb rotation, since the time series is registered in the previous indexdb, so it can be found during queries. But the time series will become invisible for search after the next indexdb rotation, while its data is still there. There is also incompletely solved issue with the increased CPU and disk IO resource usage just after the indexdb rotation. There was an attempt to fix it, but it didn't fix it in full, while introducing the issue mentioned above. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401 TODO: to find out the solution, which simultaneously solves the following issues: - increased memory usage for setups high churn rate and long retention (e.g. what the reverted commit does) - increased CPU and disk IO usage during indexdb rotation ( https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401 ) - https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2698 Possible solution - to create the new indexdb in one hour before the indexdb rotation and to gradually pre-populate it with the needed index data during the last hour before indexdb rotation. Then the new indexdb will contain all the needed data just after the rotation, so it won't trigger increased CPU and disk IO.
