Bryan Boreham	ac4f8a5e23	[ENHANCEMENT] TSDB: Improve calculation of space used by labels (#13880 ) * [ENHANCEMENT] TSDB: Improve calculation of space used by labels The labels for each series in the Head take up some some space in the Postings index, but far more space in the `memSeries` structure. Instead of having the Postings index calculate this overhead, which is a layering violation, have the caller pass in a function to do it. Provide three implementations of this function for the three Labels versions. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago

TJ Hoplock	6ebfbd2d54	chore!: adopt log/slog, remove go-kit/log For: #14355 This commit updates Prometheus to adopt stdlib's log/slog package in favor of go-kit/log. As part of converting to use slog, several other related changes are required to get prometheus working, including: - removed unused logging util func `RateLimit()` - forward ported the util/logging/Deduper logging by implementing a small custom slog.Handler that does the deduping before chaining log calls to the underlying real slog.Logger - move some of the json file logging functionality to use prom/common package functionality - refactored some of the new json file logging for scraping - changes to promql.QueryLogger interface to swap out logging methods for relevant slog sugar wrappers - updated lots of tests that used/replicated custom logging functionality, attempting to keep the logical goal of the tests consistent after the transition - added a healthy amount of `if logger == nil { $makeLogger }` type conditional checks amongst various functions where none were provided -- old code that used the go-kit/log.Logger interface had several places where there were nil references when trying to use functions like `With()` to add keyvals on the new *slog.Logger type Signed-off-by: TJ Hoplock <t.hoplock@gmail.com>	1 year ago
György Krajcsovits	44ebbb8458	Fix missing histogram copy in sampleRing The specialized version of sample add to the ring: func addH(s hSample, buf []hSample, r sampleRing) []hSample func addFH(s fhSample, buf []fhSample, r sampleRing) []fhSample already correctly copy histogram samples from the reused hReader, fhReader buffers, but the generic version does not. This means that the data is overwritten on the next read if the sample ring has seen histogram and float samples at the same time and switched to generic mode. The `genericAdd` function (which was commented anyway) is by now quite different from the specialized functions so that this commit deletes it.

Nick Pillitteri	481f14e1c0	TSDB: Don't rely on integer overflow in head compaction check (#13755 ) * TSDB: Don't compact the head block when empty Don't compact the Head block if there have not yet been any samples appended. Previously, the logic for determining if the head should be compacted relied on the default values for min and max time and integer overflow when they were checked in `Head.compactable()`. The check in `Head.compactable()` effectively did `math.MinInt64 - math.MaxInt64` which overflowed and wrapped to `1`. Since `1` is less than `1.5` times the chunk range, compaction did not happen. This was the correct behavior but relying on overflow wrapping is surprising. This change add a method for checking if the min and max time for the head is unset and uses it to short-circuit compaction in that case. It also replaces several explicit checks for the default value to determine if the head has not yet had any samples added. Signed-off-by: Nick Pillitteri <nick.pillitteri@grafana.com>	2 years ago

Marco Pracucci	501bc6419e	Add ShardedPostings() support to TSDB (#10421 ) This PR is a reference implementation of the proposal described in #10420. In addition to what described in #10420, in this PR I've introduced labels.StableHash(). The idea is to offer an hashing function which doesn't change over time, and that's used by query sharding in order to get a stable behaviour over time. The implementation of labels.StableHash() is the hashing function used by Prometheus before stringlabels, and what's used by Grafana Mimir for query sharding (because built before stringlabels was a thing). Follow up work As mentioned in #10420, if this PR is accepted I'm also open to upload another foundamental piece used by Grafana Mimir query sharding to accelerate the query execution: an optional, configurable and fast in-memory cache for the series hashes.

Justin Lei	8ef7dfdeeb	Add a chunk size limit in bytes (#12054 ) Add a chunk size limit in bytes This creates a hard cap for XOR chunks of 1024 bytes. The limit for histogram chunk is also 1024 bytes, but it is a soft limit as a histogram has a dynamic size, and even a single one could be larger than 1024 bytes. This also avoids cutting new histogram chunks if the existing chunk has fewer than 10 histograms yet. In that way, we are accepting "jumbo chunks" in order to have at least 10 histograms in a chunk, allowing compression to kick in. Signed-off-by: Justin Lei <justin.lei@grafana.com>	2 years ago

Łukasz Mierzwa	3c80963e81	Use a linked list for memSeries.headChunk (#11818 ) Currently memSeries holds a single head chunk in-memory and a slice of mmapped chunks. When append() is called on memSeries it might decide that a new headChunk is needed to use for given append() call. If that happens it will first mmap existing head chunk and only after that happens it will create a new empty headChunk and continue appending our sample to it. Since appending samples uses write lock on memSeries no other read or write can happen until any append is completed. When we have an append() that must create a new head chunk the whole memSeries is blocked until mmapping of existing head chunk finishes. Mmapping itself uses a lock as it needs to be serialised, which means that the more chunks to mmap we have the longer each chunk might wait for it to be mmapped. If there's enough chunks that require mmapping some memSeries will be locked for long enough that it will start affecting queries and scrapes. Queries might timeout, since by default they have a 2 minute timeout set. Scrapes will be blocked inside append() call, which means there will be a gap between samples. This will first affect range queries or calls using rate() and such, since the time range requested in the query might have too few samples to calculate anything. To avoid this we need to remove mmapping from append path, since mmapping is blocking. But this means that when we cut a new head chunk we need to keep the old one around, so we can mmap it later. This change makes memSeries.headChunk a linked list, memSeries.headChunk still points to the 'open' head chunk that receives new samples, while older, yet to be mmapped, chunks are linked to it. Mmapping is done on a schedule by iterating all memSeries one by one. Thanks to this we control when mmapping is done, since we trigger it manually, which reduces the risk that it will have to compete for mmap locks with other chunks.
