Series() will fetch all the metadata for a series, even if it's going to be filtered later due to time ranges. For 1M series we save ~1.1s if you only needed some of the data, but take an extra ~.2s if you did want everything. benchmark old ns/op new ns/op delta BenchmarkHeadSeries/1of1000000-4 1443715987 131553480 -90.89% BenchmarkHeadSeries/10of1000000-4 1433394040 130730596 -90.88% BenchmarkHeadSeries/100of1000000-4 1437444672 131360813 -90.86% BenchmarkHeadSeries/1000of1000000-4 1438958659 132573137 -90.79% BenchmarkHeadSeries/10000of1000000-4 1438061766 145742377 -89.87% BenchmarkHeadSeries/100000of1000000-4 1455060948 281659416 -80.64% BenchmarkHeadSeries/1000000of1000000-4 1633524504 1803550153 +10.41% benchmark old allocs new allocs delta BenchmarkHeadSeries/1of1000000-4 4000055 28 -100.00% BenchmarkHeadSeries/10of1000000-4 4000073 87 -100.00% BenchmarkHeadSeries/100of1000000-4 4000253 630 -99.98% BenchmarkHeadSeries/1000of1000000-4 4002053 6036 -99.85% BenchmarkHeadSeries/10000of1000000-4 4020053 60054 -98.51% BenchmarkHeadSeries/100000of1000000-4 4200053 600074 -85.71% BenchmarkHeadSeries/1000000of1000000-4 6000053 6000094 +0.00% benchmark old bytes new bytes delta BenchmarkHeadSeries/1of1000000-4 229192184 2488 -100.00% BenchmarkHeadSeries/10of1000000-4 229193336 5568 -100.00% BenchmarkHeadSeries/100of1000000-4 229204856 35536 -99.98% BenchmarkHeadSeries/1000of1000000-4 229320056 345104 -99.85% BenchmarkHeadSeries/10000of1000000-4 230472056 3894673 -98.31% BenchmarkHeadSeries/100000of1000000-4 241992056 40511632 -83.26% BenchmarkHeadSeries/1000000of1000000-4 357192056 402380440 +12.65% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>
