On a high-level this release:
- Adds the ability to install this software without database superuser privileges
- Adds an optional postgres extension called timescale-prometheus-extra to improve performance.
- Adds prom_reader and prom_writer roles for easy granting of read and write permission
- Simplifies the naming and usage of public functions (see docs)
- Adds informational views (see docs)
- Exposes connector metrics to Prometheus
- Improve performance by partitioning the series table
- Misc Improvements to docs and tests
Moving from alpha.2 notes
- It is suggested that you now use a database installation with the timescale-prometheus-extra extension
- Helm will do this automatically, if using the standard database image
- For docker we suggest using the
timescaledev/timescaledb-ha:pg12image - All other installation need to install from source (see readme)
- Some public function names have changed, see commit 91bd00f
- Check our new informational views (see docs)
- The service name for the connector in the helm chart has changed (a '-connector' suffix was added)
