George Krajcsovits	4eab18abd6	[nhcb branch] Use single bit to differentiate between optimized bounds and floats (#13828 ) * Use single bit to differentiate between optimized bounds and floats Use one bit to decide what kind of data to read/write. This reduces storage need of floats from 72 bits to 65 bits and makes the integers store in 5 to 32 bits instead of 16.

zenador	4acbb7dea6	Add custom buckets to native histogram chunks encoding (#13706 ) * add custom bounds to chunks encoding * change custom buckets schema number * rename custom bounds to custom values Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	8 months ago
beorn7	57c18420ab	histograms: General readability tweaks - Adjust doc comments to go1.19 style. - Break down some overly long lines. - Minor doc comment tweaks and fixes. - Some renaming. Some rationales for the last point: I have renamed “interjections” into “inserts”, mostly because it is shorter, and the word shows up a lot by now (and the concept is cryptic enough to not obfuscate it even more with abbreviations). I have also tried to find more descriptive naming for the “compare spans” functions. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
Ganesh Vernekar	8ad0d2d5d7	tsdb: Find union of two sets of histogram spans Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com>	2 years ago
Ganesh Vernekar	d7f5129042	tsdb: Add logic to determine appendable gauge float histograms This is to check if a gauge histogram can be appended to the given chunk. If not, it tells what changes to make to the chunk and the histogram if possible. Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com>	2 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.
