* feat(tsdb/chunkenc): add float chunk format with start timestamp support Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * optimize code path and layout Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * make new format usable in head Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * fix issue with seeking to last sample again Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * fix iterator benchmark for chunks not supporting ST Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * reduce footprint of the xoroptst chunk iterator object It was 80 bytes with a lot of padding compared to the 56 bytes of the original xor chunk iterator. Made it 64 bytes, tightly packed. Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * Fix benchmark expectations on ST in interator Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * add inclusive delta test case Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * make testcases independent of order Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * drop unused code Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * Drop commented out line Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * documentation Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * Small simplification in the doc Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * Add delta st inclusive test case for random vt Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * Switch to delta of difference of st to prev t from delta of delta of st. Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * Write ST after T and V so we can write a single bit on the second sample Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * verify chunk sample len function Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * Reduce size of first st stored a little Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * test the case where st equals the t Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * add st equal t to bechmarks Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * test(chunkenc): test that appender can contonue chunks Test that initializing a chunk appender from an existing chunk works correctly. Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * fix(chunkenc): bug in initializing appender on existing chunk Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * Add cases with jitter in the start time as well Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * tsdb: ST-in-WAL: Counter implementation and benchmarks (#17671) Initial implementation of https://github.com/prometheus/prometheus/issues/17790. Only implements ST-per-sample for Counters. Tests and benchmarks updated. Note: This increases the size of the RefSample object for all users, whether st-per-sample is turned on or not. Signed-off-by: Owen Williams <owen.williams@grafana.com> * refactor: sed enableStStorage/enableSTStorage Signed-off-by: bwplotka <bwplotka@gmail.com> * feat[scrape]: add ST parsing support to scrape AppenderV2 flow (#18103) Signed-off-by: bwplotka <bwplotka@gmail.com> * feat(tsdb): change head opt EnableSTStorage to atomic (#18107) In downstream projects this needs to be set dynamically per tenant. Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * Merge pull request #18108 from prometheus/bwplotka/fix scrape: add tests for ST appending; add warnings for ST feature flag users around _created drop * refact(tsdb): trivial rename (#18109) Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * fix(tsdb): missing passing head option to wal/wbl write (#18113) Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * feat(tsdb): allow using ST capable XOR chunks - retain format on read (#18013) * feat(tsdb): allow appending to ST capable XOR chunk optionally Only for float samples as of now. Supports for in-order and out-of-order samples. Make sure that on readout the ST capable chunks are returned automatically. When the chunks are returned as is, this is trivially true. When a chunk needs to be re-coded due to deletion (tombstone) markers, we take the encoding of the original chunk. When a chunk needs to be created from overlapping chunks, we observe whether ST is zero or not and create the new chunk based on that.
