Bartlomiej Plotka	e6d7cc5fa4	tsdb: Added ChunkQueryable implementations to db; unified MergeSeriesSets and vertical to single struct. (#7069 ) * tsdb: Added ChunkQueryable implementations to db; unified compactor, querier and fanout block iterating. Chained to https://github.com/prometheus/prometheus/pull/7059 * NewMerge(Chunk)Querier now takies multiple primaries allowing tsdb DB code to use it. * Added single SeriesEntry / ChunkEntry for all series implementations. * Unified all vertical, and non vertical for compact and querying to single merge series / chunk sets by reusing VerticalSeriesMergeFunc for overlapping algorithm (same logic as before) * Added block (Base/Chunk/)Querier for block querying. We then use populateAndTomb(Base/Chunk/) to iterate over chunks or samples. * Refactored endpoint tests and querier tests to include subtests.

Chris Marchbanks	b299aba6cf	Fix panic when updating a remote write queue (#7452 ) Right now Queue Manager metrics are registered when the metrics struct is created, which happens before a changed queue is shutdown and the old metrics are unregistered. In the case of named queues or updates to external labels the apply config will panic due to duplicate metrics. Instead, register the metrics as part of starting the queue as we always guarantee that Stop will be called before a new Start. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	4 years ago

Bartlomiej Plotka	b788986717	storage: Adjusted fully storage layer support for chunk iterators: Remote read client, readyStorage, fanout. (#7059 ) * Fixed nits introduced by https://github.com/prometheus/prometheus/pull/7334 * Added ChunkQueryable implementation to fanout and readyStorage. * Added more comments. * Changed NewVerticalChunkSeriesMerger to CompactingChunkSeriesMerger, removed tiny interface by reusing VerticalSeriesMergeFunc for overlapping algorithm for both chunks and series, for both querying and compacting (!) + made sure duplicates are merged. * Added ErrChunkSeriesSet * Added Samples interface for seamless []promb.Sample to []tsdbutil.Sample conversion. * Deprecating non chunks serieset based StreamChunkedReadResponses, added chunk one. * Improved tests. * Split remote client into Write (old storage) and read. * Queryable client is now SampleAndChunkQueryable. Since we cannot use nice QueryableFunc I moved all config based options to sampleAndChunkQueryableClient to aboid boilerplate. In next commit: Changes for TSDB.

Chris Marchbanks	dfad1da296	Remove duplicate metrics in QueueManager Right now any new metrics added for remote write need to be added to both the QueueManager struct, and the queueManagerMetrics struct. Instead, use the queueManagerMetrics struct directly from QueueManager. The newQueueManagerMetrics constructor will now create the metrics for a specific queue with name and endpoint pre-populated, and a new copy of the struct will be created specifically for each queue. This also fixes a bug where prometheus_remote_storage_sent_bytes_total is not being unregistered after a queue is changed. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	5 years ago

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.

beorn7	526cff39b9	Fix tests that were broken by #7009 Signed-off-by: beorn7 <beorn@grafana.com>	5 years ago
Bartlomiej Plotka	c4eefd1b3a	storage: Removed SelectSorted method; Simplified interface; Added requirement for remote read to sort response. This is technically BREAKING CHANGE, but it was like this from the beginning: I just notice that we rely in Prometheus on remote read being sorted. This is because we use selected data from remote reads in MergeSeriesSet which rely on sorting. I found during work on https://github.com/prometheus/prometheus/pull/5882 that we do so many repetitions because of this, for not good reason. I think I found a good balance between convenience and readability with just one method. Smaller the interface = better. Also I don't know what TestSelectSorted was testing, but now it's testing sorting. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>	5 years ago
Callum Styan	f802f1e8ca	Fix bug with WAL watcher and Live Reader metrics usage. (#6998 ) * Fix bug with WAL watcher and Live Reader metrics usage. Calling NewXMetrics when creating a Watcher or LiveReader results in a registration error, which we're ignoring, and as a result other than the first Watcher/Reader created, we had no metrics for either. So we would only have metrics like Watcher Records Read for the first remote write config in a users config file. Signed-off-by: Callum Styan <callumstyan@gmail.com>	5 years ago
Chris Marchbanks	3128875ff4	Fix panic when a remote read store errors (#6975 ) Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	5 years ago
beorn7	f6f4fd6556	tsdb: Do a full rollback upon commit error I think the previous behavior is problematic as it will leave `memSeries` around that still have `pendingCommit` set to `true`. The only case where this can happen in this code path is a failure to write to the WAL, in which case we are probably in trouble anyway. I believe, however, we should still try to do the right thing and do the full rollback. This will implicitly try to write to the WAL again, but this time without samples, which may even succeed. (But we propagate the previous error in any case.) This also adds `a.head.putSeriesBuffer(a.sampleSeries)` to Rollback, which was previously missing.
