8ca2799478 lib/storage: properly determine when the deduplication is needed in needsDedup
Previously needsDedup() could return true if the de-duplication wasn't needed for the following case:

         d < interval
           /     \
   |        v | v        |
     interval   interval

Now it properly returns false for this case

a7694092b8 Revert "lib/uint64set: allow reusing bucket16 structs inside uint64set.Set via uint64set.Release method"
This reverts commit 7c6d3981bf.

Reason for revert: high contention at bucket16Pool on systems with big number of CPU cores.
This slows down query processing significantly.

8aa9bba9bd lib/{mergeset,storage}: switch from sync.Pool to chan-based pool for inmemoryPart objects
This should reduce memory usage on systems with big number of CPU cores,
since every inmemoryPart object occupies at least 64KB of memory and sync.Pool maintains
a separate pool inmemoryPart objects per each CPU core.

Though the new scheme for the pool worsens per-cpu cache locality, this should be amortized
by big sizes of inmemoryPart objects.

78c9174682 lib/mergeset: increase pool capacity for inmemoryBlock according to collected profiles from production workload

0020b9f904 lib/workingsetcache: properly update stats for requests and cache misses
Previously the stats for cache misses could be improperly counted, because it had inflated cache misses
if the entry was missing in the curr cache, but was existing in the prev cache.

The same applies to cache requests - they were inflated if the entry was missing in the curr cache.

8f973e34fb lib/workingsetcache: properly switch to whole mode
Previously the switch from `split` to `whole` mode had been performed too early,
e.g. when the current cache size became bigger than 1/4 of the allowed cache size.

Now it is performed when the current cache size becomes bigger than 1/2 of the allowed cache size.

This change can reduce memory usage for data ingestion path when big number of active time series are ingested.

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

84fb59b0ba lib/storage: move deletedMetricIDs set from indexDB to Storage
This makes consitent the list of deleted metricIDs when it is used from both the current indexDB and the previous indexDB (aka extDB).
This should fix the issue, which could lead to storing new samples under deleted metricIDs after indexDB rotation.
See more details at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1347#issuecomment-861232136 .

Thanks to @tangqipengleoo for the initial analysis and the pull request - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

This commit resolves the issue in more generic way compared to https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

The downside of the commit is the deletedMetricIDs set isn't cleaned from the metricIDs outside the retention. It needs app restart.
This should be OK in most cases.

2233d6ed8a lib/uint64set: store pointers to bucket16 instead of bucket16 objects in bucket32
This speeds up bucket32.addBucketAtPos() when bucket32.buckets contains big number of items,

e05dd475f0 lib/fs: concurrently remove up to 1024 blocked NFS directories
Previously the blocked directories were removed sequentially by a single goroutine.
This can be not enough for highly loaded VictoriaMetrics that accepts millions of sample per second,
when big number of LSM parts are created and removed at high rate.

8e2985b53d lib/fs: wait for a while before giving up on NFS file removal if the removal queue is full
This should reduce the probability of the panic on a highly loaded VictoriaMetrics
accepting millions of samples per second.
