Matthieu MOREL	0906f2eafa	refactor (promql): move from github.com/pkg/errors to 'errors' and 'fmt' (#10817 ) Signed-off-by: Matthieu MOREL <mmorel-35@users.noreply.github.com> Co-authored-by: Matthieu MOREL <mmorel-35@users.noreply.github.com>	3 years ago
beorn7	d16b314b72	Histogram: Do not render empty buckets in JSON output While empty buckets can make sense in the internal representation (by joining spans that would otherwise need more overhead for separate representation), there are no spans in the JSON rendering. Therefore, the JSON should not contain any empty buckets, since any buckets not included in the output counts as empty anyway. This changes both the inefficient MarshalJSON implementation as well as the jsoniter implementation. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
beorn7	37bbc07118	Histogram: Add jsoniter marshaling This now even enables jsoniter marshaling of Points in an instant query (which previously used the traditional JSON marshaling). Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
beorn7	99894f6afa	Histogram: Implement inefficient JSON rendering Format is according to example 4 in https://docs.google.com/document/d/1Efu0LX-fgNWix6ehfeCR0FzeWtHvftWFNoy7cYW9nqU/edit# This is inefficient as it doesn't use jsoniter. It actually prevents it for regular Points (with a conventional float Value), too. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

Björn Rabenstein	7e42acd3b1	tsdb: Rework iterators (#9877 ) - Pick At... method via return value of Next/Seek. - Do not clobber returned buckets. - Add partial FloatHistogram suppert. Note that the promql package is now _only_ dealing with FloatHistograms, following the idea that PromQL only knows float values. As a byproduct, I have removed the histogramSeries metric. In my understanding, series can have both float and histogram samples, so that metric doesn't make sense anymore. As another byproduct, I have converged the sampleBuf and the histogramSampleBuf in memSeries into one. The sample type stored in the sampleBuf has been extended to also contain histograms even before this commit. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
beorn7	9672ade191	Promql: Add clarifying note to Point.MarshalJSON Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
Ganesh Vernekar	2a3d62ac84	Revert "promql: Remove unused Point.MarshalJSON method (#9860 )" (#9864 ) This reverts commit `427425cc9f`. Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com>	3 years ago
Björn Rabenstein	427425cc9f	promql: Remove unused Point.MarshalJSON method (#9860 ) JSON marshaling is only needed for the HTTP API. Since Point is such a frequently marshaled type, it gets an optimized treatment directly in web/api/v1/api.go. The MarshalJSON method still provided in the promql package is therefore unused and its existence is confusing. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

beorn7	4c28d9fac7	Move to histogram.Histogram pointers This is to avoid copying the many fields of a histogram.Histogram all the time. This also fixes a bunch of formerly broken tests. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

beorn7	7a8bb8222c	Style cleanup of all the changes in sparsehistogram so far A lot of this code was hacked together, literally during a hackathon. This commit intends not to change the code substantially, but just make the code obey the usual style practices. A (possibly incomplete) list of areas: * Generally address linter warnings. * The `pgk` directory is deprecated as per dev-summit. No new packages should be added to it. I moved the new `pkg/histogram` package to `model` anticipating what's proposed in #9478. * Make the naming of the Sparse Histogram more consistent. Including abbreviations, there were just too many names for it: SparseHistogram, Histogram, Histo, hist, his, shs, h. The idea is to call it "Histogram" in general. Only add "Sparse" if it is needed to avoid confusion with conventional Histograms (which is rare because the TSDB really has no notion of conventional Histograms). Use abbreviations only in local scope, and then really abbreviate (not just removing three out of seven letters like in "Histo"). This is in the spirit of https://github.com/golang/go/wiki/CodeReviewComments#variable-names * Several other minor name changes. * A lot of formatting of doc comments. For one, following https://github.com/golang/go/wiki/CodeReviewComments#comment-sentences , but also layout question, anticipating how things will look like when rendered by `godoc` (even where `godoc` doesn't render them right now because they are for unexported types or not a doc comment at all but just a normal code comment - consistency is queen!). * Re-enabled `TestQueryLog` and `TestEndopints` (they pass now, leaving them disabled was presumably an oversight). * Bucket iterator for histogram.Histogram is now created with a method. * HistogramChunk.iterator now allows iterator recycling. (I think @dieterbe only commented it out because he was confused by the question in the comment.) * HistogramAppender.Append panics now because we decided to treat staleness marker differently.

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
