0.14.0

At a high-level, this release contains

• Support for native Jaeger gRPC interface to ingest traces. Now you can send traces from Jaeger collector/agent/SDK by configuring the endpoint as http://promscale:9202
• Improvements to querying (PromQL and Traces)

Requirements

PostgreSQL: 12.x, 13.x, 14.x
TimescaleDB: >= 2.7.0 single-node (multi-node is not supported in this release)
Promscale Database Extension: >=0.6

Upgrade notes

• Before starting the upgrade please make sure that you have deployed version 0.6 of the Promscale extension. You will also need TimescaleDB extension version 2.7.0 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.

• Implement Jaeger gRPC remote storage writer interface [#1543]
• Batching for traces to improve ingest performance along with CLI flags for better control [#1554]
• Helm chart now ships a JSON Schema for imposing a structure of the values.yaml file [#1551]

Changes

• Helm chart code was migrated to https://github.com/timescale/helm-charts [#1562]

Deprecations

Fixes

• Reset inverted labels cache on epoch change [#1561]
• Error column "exemplar_label_values" does not exist (SQLSTATE 42703) on ingesting exemplars [#1574]
• /api/v1/labels & /api/v1/label/{name}/values to respond with labels of authorized tenants only [#1577]
