TSDB: 1 Year In

Speaker: Ganesh Vernekar

Since a major revamp of the Prometheus storage engine as part of the Prometheus 2.0 release, there have been a lot of enhancements and feature additions in TSDB.

In this talk I will speak about all that has gone into TSDB since 2.0 was released, some of the notable ones include:

  • Backfilling
  • Disk size based retention
  • WAL compression and read optimizations
  • Postings compression and lifting the 64 GiB index size limit to be practically unlimited
  • Allocation and memory optimization for compaction
  • Various optimization for the queries
  • Read Only mode
  • Isolation

I will also talk about how each of these developments impacted Prometheus and how devs embedding them in their own apps can leverage them.
