Brian Brazil 2b653ee230 Write label indices based on the posting offset table. ... This avoids having to build it up in RAM, and means that all variable memory usage for compactions is now 0.25 bytes per symbol plus a few O(labelnames) structures. So in practice, pretty close to constant memory for compactions. benchmark old ns/op new ns/op delta BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 662974828 667162981 +0.63% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 2459590377 2131168138 -13.35% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 3808280548 3919290378 +2.91% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 8513884311 8738099339 +2.63% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 1898843003 1944131966 +2.39% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 5601478437 6031391658 +7.67% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 11225096097 11359624463 +1.20% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 23994637282 23919583343 -0.31% BenchmarkCompactionFromHead/labelnames=1,labelvalues=100000-4 891042098 826898358 -7.20% BenchmarkCompactionFromHead/labelnames=10,labelvalues=10000-4 915949138 902555676 -1.46% BenchmarkCompactionFromHead/labelnames=100,labelvalues=1000-4 955138431 879067946 -7.96% BenchmarkCompactionFromHead/labelnames=1000,labelvalues=100-4 991447640 958785968 -3.29% BenchmarkCompactionFromHead/labelnames=10000,labelvalues=10-4 1068729356 980249080 -8.28% benchmark old allocs new allocs delta BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 470778 470556 -0.05% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 791429 791225 -0.03% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 1111514 1111257 -0.02% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 2111498 2111369 -0.01% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 841433 841220 -0.03% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 1911469 1911202 -0.01% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 3041558 3041328 -0.01% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 6741534 6741382 -0.00% BenchmarkCompactionFromHead/labelnames=1,labelvalues=100000-4 824856 820873 -0.48% BenchmarkCompactionFromHead/labelnames=10,labelvalues=10000-4 887220 885180 -0.23% BenchmarkCompactionFromHead/labelnames=100,labelvalues=1000-4 905253 901539 -0.41% BenchmarkCompactionFromHead/labelnames=1000,labelvalues=100-4 925148 913632 -1.24% BenchmarkCompactionFromHead/labelnames=10000,labelvalues=10-4 1019141 978727 -3.97% benchmark old bytes new bytes delta BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 35694744 41523836 +16.33% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 53405264 59499056 +11.41% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 74160320 78151568 +5.38% BenchmarkCompaction/type=normal,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 120878480 135364672 +11.98% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=101-4 203832448 209925504 +2.99% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=1001-4 341029208 346551064 +1.62% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=2001-4 580217176 582345224 +0.37% BenchmarkCompaction/type=vertical,blocks=4,series=10000,samplesPerSeriesPerBlock=5001-4 1356872288 1363495368 +0.49% BenchmarkCompactionFromHead/labelnames=1,labelvalues=100000-4 119535672 94815920 -20.68% BenchmarkCompactionFromHead/labelnames=10,labelvalues=10000-4 115352280 95980776 -16.79% BenchmarkCompactionFromHead/labelnames=100,labelvalues=1000-4 119472320 98724460 -17.37% BenchmarkCompactionFromHead/labelnames=1000,labelvalues=100-4 111979312 94325456 -15.77% BenchmarkCompactionFromHead/labelnames=10000,labelvalues=10-4 116628584 98566344 -15.49% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>		2019-12-18 12:05:42 +00:00
