c93cee8de8 lib/{mergeset,storage}: reduce the maximum lifetime for cached indexdb and data blocks from 2 minutes to a minute
This should reduce memory usage on a system with high number of active time series and a high churn rate.
One minute is enough for caching the blocks needed for repeated queries (e.g. alerting rules, recording rules and dashboard refreshes).

fc12484734 lib/mergeset: switch from sync.Pool to a channel for a pool for inmemoryBlock structs
This should reduce memory usage for the pool on systems with big number of CPU cores.

The sync.Pool maintains per-CPU pools, so the total number of objects in the pool
is proportional to the number of available CPU cores. The channel limits the number
of pooled objects by its own capacity. This means smaller number of pooled objects on average.

c22114c6f0 lib/storage: tune tag filters search logic
Tune the logic according to the logs provided at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-864293624

The previous logic had a race when multiple concurrent queries execute the same tag filter without prior stats.
This could result in incorrectly stored stats for such tag filter, which then could result in non-optimal sorting of tag filters
for further queries.

aa9b56a046 lib/{mergeset,storage}: reduce the number of fsync calls on data ingestion path on systems with many cpu cores
VictoriaMetrics maintains a buffer per CPU core for the ingested data. These buffers are flushed to disk every second.
These buffers are flushed to disk in parallel starting from the commit 56b6b893ce .
This resulted in increased write disk IO usage on systems with many cpu cores
as described at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338#issuecomment-863046999 .

This commit merges the per-CPU buffers into bigger in-memory buffers before flushing them to disk.
This should reduce the rate of fsync syscalls and, consequently, the write disk IO on systems with many CPU cores.

This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1338
