Giedrius Statkevičius	3a48adc54f	tsdb: add enable overlapping compaction This functionality is needed in downstream projects because they have a separate component that does compaction.

Giedrius Statkevičius	61b4080a14	tsdb/{index,compact}: allow using custom postings encoding format (#13242 ) * tsdb/{index,compact}: allow using custom postings encoding format We would like to experiment with a different postings encoding format in Thanos so in this change I am proposing adding another argument to `NewWriter` which would allow users to change the format if needed. Also, wire the leveled compactor so that it would be possible to change the format there too.

George Krajcsovits	7d7b9eacff	Fix int32 overflow issues (#12978 ) On a 32 bit architecture the size of int is 32 bits. Thus converting from int64, uint64 can overflow it and flip the sign. Try for yourself in playground: package main import "fmt" func main() { x := int64(0x1F0000001) y := int64(1) z := int32(x - y) // numerically this is 0x1F0000000 fmt.Printf("%v\n", z) } Prints -268435456 as if x was smaller.

Oleg Zaytsev	344c630857	Fix context.Canceled wrapping in compaction We need to make sure that `tsdb_errors.NewMulti` handles the errors.Is() calls properly, like it's done in grafana/dskit. Also we need to check that `errors.Is(err, context.Canceled)`, not that `err == context.Canceled`. Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	2 years ago
Bryan Boreham	3c7de69059	storage: allow re-use of iterators Patterned after `Chunk.Iterator()`: pass the old iterator in so it can be re-used to avoid allocating a new object. (This commit does not do any re-use; it is just changing all the method signatures so re-use is possible in later commits.) Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago

Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536 ) * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.

Goutham Veeramachaneni	e572e77d90	Increase the buckets for compaction duration (#8342 ) We're seeing compactions that are taking hours in Cortex which this is missing. I know while it is not common in Prometheus, I am pretty sure there are setups where compaction takes longer than 512s. On our own Prometheus the average compaction duration is 566s.

Bartlomiej Plotka	d5c33877f9	storage: Added Chunks{Queryable/Querier/SeriesSet/Series/Iteratable. Added generic Merge{SeriesSet/Querier} implementation. (#7005 ) * storage: Added Chunks{Queryable/Querier/SeriesSet/Series/Iteratable. Added generic Merge{SeriesSet/Querier} implementation. ## Rationales: In many places (e.g. chunk Remote read, Thanos Receive fetching chunk from TSDB), we operate on encoded chunks not samples. This means that we unnecessary decode/encode, wasting CPU, time and memory. This PR adds chunk iterator interfaces and makes the merge code to be reused between both seriesSets I will make the use of it in following PR inside tsdb itself. For now fanout implements it and mergers. All merges now also allows passing series mergers. This opens doors for custom deduplications other than TSDB vertical ones (e.g. offline one we have in Thanos). ## Changes * Added Chunk versions of all iterating methods. It all starts in Querier/ChunkQuerier. The plan is that Storage will implement both chunked and samples. * Added Seek to chunks.Iterator interface for iterating over chunks. * NewMergeChunkQuerier was added; Both this and NewMergeQuerier are now using generigMergeQuerier to share the code. Generic code was added. * Improved tests. * Added some TODO for further simplifications in next PRs. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com> * Addressed Brian's comments.

Bartlomiej Plotka	34426766d8	Unify Iterator interfaces. All point to storage now. This is part of https://github.com/prometheus/prometheus/pull/5882 that can be done to simplify things. All todos I added will be fixed in follow up PRs. * querier.Querier, querier.Appender, querier.SeriesSet, and querier.Series interfaces merged with storage interface.go. All imports that. * querier.SeriesIterator replaced by chunkenc.Iterator * Added chunkenc.Iterator.Seek method and tests for xor implementation (?) * Since we properly handle SelectParams for Select methods I adjusted min max based on that. This should help in terms of performance for queries with functions like offset. * added Seek to deletedIterator and test. * storage/tsdb was removed as it was only a unnecessary glue with incompatible structs. No logic was changed, only different source of abstractions, so no need for benchmarks. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>	5 years ago

Brian Brazil	d782387f81	Stream symbols during compaction. (#6468 ) Rather than buffer up symbols in RAM, do it one by one during compaction. Then use the reader's symbol handling for symbol lookups during the rest of the index write. There is some slowdown in compaction, due to having to look through a file rather than a hash lookup. This is noise to the overall cost of compacting series with thousands of samples though. benchmark old ns/op new ns/op delta BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 539917175 675341565 +25.08% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 2441815993 2477453524 +1.46% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 3978543559 3922909687 -1.40% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 8430219716 8586610007 +1.86% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 1786424591 1909552782 +6.89% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 5328998202 6020839950 +12.98% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 10085059958 11085278690 +9.92% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 25497010155 27018079806 +5.97% BenchmarkCompactionFromHead/labelnames=1,labelvalues=100000-4 2427391406 2817217987 +16.06% BenchmarkCompactionFromHead/labelnames=10,labelvalues=10000-4 2592965497 2538805050 -2.09% BenchmarkCompactionFromHead/labelnames=100,labelvalues=1000-4 2437388343 2668012858 +9.46% BenchmarkCompactionFromHead/labelnames=1000,labelvalues=100-4 2317095324 2787423966 +20.30% BenchmarkCompactionFromHead/labelnames=10000,labelvalues=10-4 2600239857 2096973860 -19.35% benchmark old allocs new allocs delta BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 500851 470794 -6.00% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 821527 791451 -3.66% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 1141562 1111508 -2.63% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 2141576 2111504 -1.40% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 871466 841424 -3.45% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 1941428 1911415 -1.55% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 3071573 3041510 -0.98% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 6771648 6741509 -0.45% BenchmarkCompactionFromHead/labelnames=1,labelvalues=100000-4 731493 824888 +12.77% BenchmarkCompactionFromHead/labelnames=10,labelvalues=10000-4 793918 887311 +11.76% BenchmarkCompactionFromHead/labelnames=100,labelvalues=1000-4 811842 905204 +11.50% BenchmarkCompactionFromHead/labelnames=1000,labelvalues=100-4 832244 925081 +11.16% BenchmarkCompactionFromHead/labelnames=10000,labelvalues=10-4 921553 1019162 +10.59% benchmark old bytes new bytes delta BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 40532648 35698276 -11.93% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 60340216 53409568 -11.49% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 81087336 72065552 -11.13% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 142485576 120878544 -15.16% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 208661368 203831136 -2.31% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 347345904 340484696 -1.98% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 585185856 576244648 -1.53% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 1357641792 1358966528 +0.10% BenchmarkCompactionFromHead/labelnames=1,labelvalues=100000-4 126486664 119666744 -5.39% BenchmarkCompactionFromHead/labelnames=10,labelvalues=10000-4 122323192 115117224 -5.89% BenchmarkCompactionFromHead/labelnames=100,labelvalues=1000-4 126404504 119469864 -5.49% BenchmarkCompactionFromHead/labelnames=1000,labelvalues=100-4 119047832 112230408 -5.73% BenchmarkCompactionFromHead/labelnames=10000,labelvalues=10-4 136576016 116634800 -14.60% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	5 years ago
Brian Brazil	0482d93fe6	Add contexts to index writer to fix test races. With recent speed improvements to populate block, the cancellation test now fails regularly on CI. Use contexts to get the index writer to shut down much faster, and that allows us to make the cancellation test faster too. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	5 years ago
Brian Brazil	373a1fdfbf	Reread index series rather than storing in memory. Rather than building up a 2nd copy of all the posting tables, construct it from the data we've already written to disk. This takes more time, but saves memory. Current benchmark numbers have this as slightly faster, but that's likely due to the synthetic data not having many label names. Memory usage is roughly halved for the relevant bits. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	5 years ago
