lib/{storage,mergeset}: tune the threshold for assisted merge
...
The https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3425#issuecomment-1359117221
reveals that CPU usage for incoming queries may significantly increase when the number
of in-memory parts becomes too big.
This commit reduces the maximum number of in-memory parts before starting the assisted merge
during data ingestion. This should reduce CPU usage for incoming queries,
since they need to inspect lower number of in-memory parts.
This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3425

actions supported by VictoriaMetrics since June 2020 - see 2a39ba639d

lib/{mergeset,storage}: do not block small merges by pending big merges - assist with small merges instead

Blocked small merges may result into big number of small parts, which, in turn,

lib/bytesutil: cache results for all the input strings, which were passed during the last 5 minutes from FastStringMatcher.Match(), FastStringTransformer.Transform() and InternString()
...
Previously only up to 100K results were cached.
This could result in sub-optimal performance when more than 100K unique strings were actually used.
For example, when the relabeling rule was applied to a million of unique Graphite metric names
like in the https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3466
This commit should reduce the long-term CPU usage for https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3466
after all the unique Graphite metrics are registered in the FastStringMatcher.Transform() cache.
It is expected that the number of unique strings, which are passed to FastStringMatcher.Match(),
FastStringTransformer.Transform() and to InternString() during the last 5 minutes,
is limited, so the function results fit memory. Otherwise OOM crash can occur.
This should be the case for typical production workloads.

7d5c64eb7a
all: add -inmemoryDataFlushInterval command-line flag for controlling the frequency of saving in-memory data to disk
...
The main purpose of this command-line flag is to increase the lifetime of low-end flash storage
with the limited number of write operations it can perform. Such flash storage is usually
installed on Raspberry PI or similar appliances.
For example, `-inmemoryDataFlushInterval=1h` reduces the frequency of disk write operations
to up to once per hour if the ingested one-hour worth of data fits the limit for in-memory data.
The in-memory data is searchable in the same way as the data stored on disk.
VictoriaMetrics automatically flushes the in-memory data to disk on graceful shutdown via SIGINT signal.
The in-memory data is lost on unclean shutdown (hardware power loss, OOM crash, SIGKILL).

lib/workingsetcache: tune cache miss threshold for resetting the previous cache from 5% to 1%
...
It has been appeared that some production workloads could suffer for some time
after every reset of the previous cache when it gets less than 5% of requests
after the needed item isn't found in the current cache. This could result
in reduced cache hit rates, which, in turn, could increase CPU, disk IO and RAM
usage needed for reading, unpacking and caching the missed data from disk.
This commit reduces the cache miss threshold for resetting the previous cache from 5% to 1%.
This should reduce the possible negative impact after each cache reset by at least 5x,
while reducing the total memory used by caches.

lib/promscrape: properly add exported_ prefix to labels, which clash with target labels if honor_labels: true option isn't set.
...
The issue was in the `labels := dst[offset:]` line in the beginning of appendExtraLabels() function.
The `dst` may be re-allocated when adding extra labels to it. In this case the addition of `exported_`
prefix to labels inside `labels` slice become invisible in the returned `dst` labels.
While at it, properly handle some corner cases:
- Add additional `exported_` prefix to clashing metric labels with already existing `exported_` prefix.
- Store scraped metric names in `exported___name__` label if scrape target contains `__name__` label.

lib/storage: subsitute searchTSIDs functions with more lightweight searchMetricIDs function
...
The searchTSIDs function was searching for metricIDs matching the the given tag filters
and then was locating the corresponding TSID entries for the found metricIDs.
The TSID entries aren't needed when searching for time series names (aka MetricName),
so this commit removes the uneeded TSID search from the implementation of /api/v1/series API.
This improves perfromance of /api/v1/series calls.
This commit also improves performance a bit for /api/v1/query and /api/v1/query_range calls,
since now these calls cache small metricIDs instead of big TSID entries
in the indexdb/tagFilters cache (now this cache is named indexdb/tagFiltersToMetricIDs)
without the need to compress the saved entries in order to save cache space.
This commit also removes concurrency limiter during searching for matching time series,
