timescale/promscale 0.13.0

on GitHub

At a high level, this release

• Improves metric ingestion by using COPY to get better performance [#1462]
• Introduces separate connection pools for reader and writer [#1451]

Requirements

• PostgreSQL: 12.x, 13.x, 14.x.
• TimescaleDB: >= 2.6.1 single-node (multi-node is not supported in this release)
• Promscale Database Extension: 0.5.4.

Upgrade notes

• Before starting the upgrade please make sure that you have deployed version 0.5.4 of the Promscale extension. You will also need TimescaleDB extension version 2.6.1 or above available. Then stop all Promscale Connector instances, upgrade the first one and restart it. The migration will happen automatically. Once the migration is completed, upgrade the remaining Promscale instances and restart them if needed.

Improvements

• Support for glob in rule_files [#1443]

Fixes

• Refine check for existence of prom_schema_migrations table [#1452]
• Do not run rules-manager in -db.read-only mode [#1451]
• Fix underlying metric(promscale_sql_database_chunks_count) which leads to false positive firing of PromscaleCompressionLow alert [#1494]
• Fix RE2 regex support for label matching [#1441]
• Remove flaky PromscaleCacheTooSmall alert [#1498]
• db.num-writer-connections now sets the absolute number of write connections for writing metrics. [#1430]

Helm Chart Improvements

• Add ability to specify Deployment annotations and Pod annotations in helm charts [#1495]
• Allow disabling exposition of promscale port in Service object. [#1495]
• Enable prometheus annotation based scraping only when ServiceMonitor is disabled. [#1495]

Deprecations

• Deprecate openTelemetry and prometheus top-level objects in helm chart in favour of .service.openTelemetry and .service.prometheus [#1495]
