This will create the ability to create highly available querying architecture when multiple independent VictoriaMetrics clusters with the same data are located in distinct availability zones. In this case we can use top-level vmselect instead of Promxy for simultaneous querying of all the clusters in all the AZs.	2022-06-27 14:20:41 +03:00

If the previous dial attempt was unsuccessful, then all the new dial attempts are skipped until the background goroutine determines that the given address can be successfully dialed. This reduces query latency when some of vmstorage nodes are unavailable and dialing them is slow. This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/711 This commit is based on ideas from the https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2756 The main differences are: - The check for healthy/unhealthy storage nodes is moved one level lower from app/vmselect/netstorage to lib/netutil.ConnPool. This makes possible re-using this feature everywhere lib/netutil.ConnPool is used. - The check doesn't take into account handshake errors for already established connections. Handshake errors usually mean improperly configured VictoriaMetrics cluster, so they shouldn't be ignored.	2022-06-20 17:33:54 +03:00

Roman Khavronenko	5f33445f66	lib/storage: limit max mergeConcurrency value for systems with high number of CPUs (#2673) ... Workers count for merges affects the max part size during merges. Such behaviour protects storage from running out of disk space for scenario when all workers are merging parts with the max size. This works very well for most cases. But for systems where high number of CPUs is allocated for vmstorage components this could significantly impact the max part size and result in more unmerged parts than expected. While checking multiple production highly loaded setups it was discovered that `max_over_time(vm_active_merges{type="storage/big}[1h]}"` rarely exceeds 2, and `max_over_time(vm_active_merges{type="storage/small}[1h]}"` rarely exceeds 4. The change in this commit limits the max value for concurrency accordingly. Signed-off-by: hagen1778 <roman@victoriametrics.com>	2022-06-07 15:02:55 +03:00

Roman Khavronenko	d107f86fbc	lib/index: reduce read/write load after indexDB rotation (#2177) ... * lib/index: reduce read/write load after indexDB rotation IndexDB in VM is responsible for storing TSID - ID's used for identifying time series. The index is stored on disk and used by both ingestion and read path. IndexDB is stored separately to data parts and is global for all stored data. It can't be deleted partially as VM deletes data parts. Instead, indexDB is rotated once in `retention` interval. The rotation procedure means that `current` indexDB becomes `previous`, and new freshly created indexDB struct becomes `current`. So in any time, VM holds indexDB for current and previous retention periods. When time series is ingested or queried, VM checks if its TSID is present in `current` indexDB. If it is missing, it checks the `previous` indexDB. If TSID was found, it gets copied to the `current` indexDB. In this way `current` indexDB stores only series which were active during the retention period. To improve indexDB lookups, VM uses a cache layer called `tsidCache`. Both write and read path consult `tsidCache` and on miss the relad lookup happens. When rotation happens, VM resets the `tsidCache`. This is needed for ingestion path to trigger `current` indexDB re-population. Since index re-population requires additional resources, every index rotation event may cause some extra load on CPU and disk. While it may be unnoticeable for most of the cases, for systems with very high number of unique series each rotation may lead to performance degradation for some period of time. This PR makes an attempt to smooth out resource usage after the rotation. The changes are following: 1. `tsidCache` is no longer reset after the rotation; 2. Instead, each entry in `tsidCache` gains a notion of indexDB to which they belong; 3. On ingestion path after the rotation we check if requested TSID was found in `tsidCache`. Then we have 3 branches: 3.1 Fast path. It was found, and belongs to the `current` indexDB. Return TSID. 3.2 Slow path. It wasn't found, so we generate it from scratch, add to `current` indexDB, add it to `tsidCache`. 3.3 Smooth path. It was found but does not belong to the `current` indexDB. In this case, we add it to the `current` indexDB with some probability. The probability is based on time passed since the last rotation with some threshold. The more time has passed since rotation the higher is chance to re-populate `current` indexDB. The default re-population interval in this PR is set to `1h`, during which entries from `previous` index supposed to slowly re-populate `current` index. The new metric `vm_timeseries_repopulated_total` was added to identify how many TSIDs were moved from `previous` indexDB to the `current` indexDB. This metric supposed to grow only during the first `1h` after the last rotation. https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401 Signed-off-by: hagen1778 <roman@victoriametrics.com> * wip * wip Co-authored-by: Aliaksandr Valialkin <valyala@victoriametrics.com>	2022-02-12 00:34:44 +02:00

Aliaksandr Valialkin	10476738a8	lib/blockcache: increase the lifetime for rarely accessed blocks from 2 minutes to 5 minutes ... This should improve data ingestion speed if time series samples are ingested with interval bigger than 2 minutes. The actual interval could exceed 2 minutes if the original interval between samples doesn't exceed 2 minutes in the case of slow inserts. Slow inserts may appear in the following cases: * Big number of new time series are pushed to VictoriaMetrics, so they couldn't be registered in 2 minutes. * MetricName->tsid cache reset on indexdb rotation or due to unclean shutdown. In this case VictoriaMetrics needs to load MetricName->tsid entries for all the incoming series from IndexDB. IndexDB uses the block cache for increasing lookup performance. If the cache has no the needed block, then IndexDB reads and unpacks the block from disk. This requires an extra disk read IO and CPU. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007 This also should increase performance for periodically executed queries with intervals from 2 minutes to 5 minutes. See the previous similar commit - 43103be011 It is possible that the timeout can be increased further.

Aliaksandr Valialkin	6232eaa938	lib/bytesutil: split Resize() into ResizeNoCopy() and ResizeWithCopy() functions ... Previously bytesutil.Resize() was copying the original byte slice contents to a newly allocated slice. This wasted CPU cycles and memory bandwidth in some places, where the original slice contents wasn't needed after slize resizing. Switch such places to bytesutil.ResizeNoCopy(). Rename the original bytesutil.Resize() function to bytesutil.ResizeWithCopy() for the sake of improved readability. Additionally, allocate new slice with `make()` instead of `append()`. This guarantees that the capacity of the allocated slice exactly matches the requested size. The `append()` could return a slice with bigger capacity as an optimization for further `append()` calls. This could result in excess memory usage when the returned byte slice was cached (for instance, in lib/blockcache).

Aliaksandr Valialkin	0452a8d4e8	lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice ... This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode at the cost of the increased memory usage, since now the potentially big response is kept in the lastScrape byte slice per each scrapeWork. In practice the memory usage increase shouldn't be big, since the response size is usually much smaller than the parsed metrics from this response after the relabeling, which usually adds a big pile of target-specific labels per each metric.	2021-10-15 15:26:24 +03:00

Aliaksandr Valialkin	a846febc89	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.	2021-07-06 18:26:56 +03:00
Aliaksandr Valialkin	b805a675f3	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.	2021-07-06 16:33:25 +03:00

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.

Aliaksandr Valialkin	bced9ee666	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).	2021-06-29 19:57:53 +03:00
Aliaksandr Valialkin	b7c0b3dde3	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.	2021-06-29 19:57:52 +03:00

Aliaksandr Valialkin	0efd37cec1	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 See also https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1244	2021-06-17 13:51:42 +03:00
Aliaksandr Valialkin	b133de1e37	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 .
