First release. Currently all features are experimental, and may change by future versions; do not use them if you will unable to handle that. In particular, the schema containing the experimental features will be dropped and recreated in the upgrade script, so do not create any objects (views, continuous aggregates, tables, functions, etc.) that rely on features in the experimental schema unless you are ok with said objects being dropped on upgrade.

There are no stable features added in this release.

Notable experimental features in this release include:

  • Hyperloglog – An approximate COUNT DISTINCT based on hashing that provides reasonable accuracy in constant space.
  • T-Digest – A quantile estimate sketch optimized to provide more accurate estimates near the tails (i.e. 0.001 or 0.995) than conventional approaches.
  • UddSketch – A quantile estimate sketch which provides a guaranteed maximum relative error.
  • Time-weighted average – A time-weighted averaging function to determine the value of things proportionate to the time they are set.
