Internal improvements and prep work for 1.0

0.2.0 Cloud Edition

Version 0.2.0 with more permissive permissions to work correctly when provided by a managed environment. Use the regular version of the release, unless you have specific reason to use this one.

0.2.0

This release contains more experimental
features, along with additional functionality for prior features.

New Experimental features:

• ASAP Smoothing – A graph smoothing algorithm that
  highlights changes.
• Counter Aggregates – Tools to ease working
  with reset-able counters.
• Largest Triangle Three Buckets – A downsampling
  algorithm that tries to preserve visual similarity.
• Time Bucket Range – A version of time_bucket() that outputs the [start, end) times of the bucket.

In addition, we've updated UddSketch with an
aggregate that merges multiple UddSketchs and various internal improvements.

0.1.0

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.

0.1.0-beta

Test release for Forge integration, if this works, it will be promoted to a real release.
