Owen Diehl dbbadafca2 Tsdb/v3 (#9070) ... brief: adds page support for chunks within a series. This lets us do a few optimizations, most notably skipping chunk ranges that don't overlap with our query bounds. It also allows us to use aggregated stats for pages when computing `Stats` calls that completely overlap all chunks in a page. teaser: ``` pkg: github.com/grafana/loki/pkg/storage/stores/tsdb/index BenchmarkChunkStats/version_2/2_chunks-10 10121240 109.4 ns/op 24 B/op 1 allocs/op BenchmarkChunkStats/version_3/2_chunks-10 27591069 43.51 ns/op 0 B/op 0 allocs/op BenchmarkChunkStats/version_2/4_chunks-10 9410245 128.7 ns/op 24 B/op 1 allocs/op BenchmarkChunkStats/version_3/4_chunks-10 21808070 54.44 ns/op 0 B/op 0 allocs/op BenchmarkChunkStats/version_2/10_chunks-10 6048235 201.3 ns/op 24 B/op 1 allocs/op BenchmarkChunkStats/version_3/10_chunks-10 9517605 125.1 ns/op 0 B/op 0 allocs/op BenchmarkChunkStats/version_2/100_chunks-10 1000000 1081 ns/op 24 B/op 1 allocs/op BenchmarkChunkStats/version_3/100_chunks-10 1669972 715.4 ns/op 528 B/op 3 allocs/op BenchmarkChunkStats/version_2/1000_chunks-10 118125 10165 ns/op 24 B/op 1 allocs/op BenchmarkChunkStats/version_3/1000_chunks-10 570576 2125 ns/op 4816 B/op 6 allocs/op BenchmarkChunkStats/version_2/10000_chunks-10 10000 117447 ns/op 123014 B/op 3 allocs/op BenchmarkChunkStats/version_3/10000_chunks-10 74524 16225 ns/op 48601 B/op 9 allocs/op BenchmarkChunkStats/version_2/100000_chunks-10 842 1240380 ns/op 3211679 B/op 13 allocs/op BenchmarkChunkStats/version_3/100000_chunks-10 8494 141169 ns/op 516530 B/op 13 allocs/op ``` ``` pkg: github.com/grafana/loki/pkg/storage/stores/tsdb/index BenchmarkReadChunks/version_2/2_chunks-10 13673050 80.52 ns/op 172 B/op 0 allocs/op BenchmarkReadChunks/version_3/2_chunks-10 25713412 64.06 ns/op 201 B/op 0 allocs/op BenchmarkReadChunks/version_2/4_chunks-10 12302040 96.56 ns/op 373 B/op 0 allocs/op BenchmarkReadChunks/version_3/4_chunks-10 20512030 84.93 ns/op 346 B/op 0 allocs/op BenchmarkReadChunks/version_2/10_chunks-10 6974947 168.7 ns/op 490 B/op 0 allocs/op BenchmarkReadChunks/version_3/10_chunks-10 7436360 161.0 ns/op 632 B/op 0 allocs/op BenchmarkReadChunks/version_2/50_chunks-10 2038724 599.3 ns/op 2034 B/op 0 allocs/op BenchmarkReadChunks/version_3/50_chunks-10 2251822 619.8 ns/op 1926 B/op 0 allocs/op BenchmarkReadChunks/version_2/100_chunks-10 946430 1092 ns/op 4132 B/op 0 allocs/op BenchmarkReadChunks/version_3/100_chunks-10 1467297 1000 ns/op 3308 B/op 1 allocs/op BenchmarkReadChunks/version_2/150_chunks-10 674575 1721 ns/op 5767 B/op 0 allocs/op BenchmarkReadChunks/version_3/150_chunks-10 1000000 1373 ns/op 6171 B/op 1 allocs/op BenchmarkReadChunks/version_2/1000_chunks-10 109153 10554 ns/op 33063 B/op 0 allocs/op BenchmarkReadChunks/version_3/1000_chunks-10 158086 6963 ns/op 32829 B/op 1 allocs/op BenchmarkReadChunks/version_2/10000_chunks-10 9043 114121 ns/op 345258 B/op 0 allocs/op BenchmarkReadChunks/version_3/10000_chunks-10 22083 79896 ns/op 435493 B/op 1 allocs/op BenchmarkReadChunks/version_2/100000_chunks-10 1039 1103621 ns/op 3479873 B/op 0 allocs/op BenchmarkReadChunks/version_3/100000_chunks-10 2101 1155419 ns/op 4680266 B/op 1 allocs/op ``` --------- Signed-off-by: Owen Diehl <ow.diehl@gmail.com>		2 years ago
