This release contains official support for TimescaleDB 2.0 (single-node) as well as various bug fixes and code cleanup.
Please note that multinode support is still in alpha and automatic upgrades of multinode deployments to future versions is not yet guaranteed (we hope to support this starting with the next release). Please only use multinode deployments for testing only.
Notes for people upgrading from 0.1.3:
- The dropChunk property in the Promscale Helm chart is renamed to maintenance. The drop-chunks CRON job is now renamed to maintenance, you will need to replace the dropChunk.schedule value with maintenance.schedule.
- If using TimescaleDB 2.0: You should manually execute:
SELECT delete_job(job_id) FROM timescaledb_information.jobs WHERE proc_schema = '_prom_catalog' AND proc_name = 'compression_job'SELETC config_maintenance_jobs(2, '30 min')
Notes for people upgrading timescaleDB 1.x -> 2.x
- You should run
SELECT remove_compression_policy(format('prom_data.%I', table_name), if_exists=>true) FROM _prom_catalog.metric;after the upgrade. This cleans up the old way of running compression jobs, compression will still work (just in the new way).
Notes for multinode deployments
- This should only be used for testing, not production deployments
- In particular, we are not guaranteeing upgrades from 0.1.4 to future versions in multinode deployments.
- All nodes have to be added to the cluster before starting Promscale; adding nodes afterwards is not yet supported.
