How sparse histograms can improve efficiency, precision, and mergeability in Prometheus TSDB
Grafana Labs recently hosted its first company-wide hackathon, and we joined forces with Björn “Beorn” Rabenstein to bring sparse high-resolution histograms in Prometheus TSDB into a working prototype. The Prometheus TSDB has gained experimental support to store and retrieve these new sparse high-resolution histograms. At PromCon 2021, we presented our exciting, fresh-off-the-presses results from the ongoing project.
