Upgrade

Don't skip minor versions when upgrading or downgrading

Skipping versions when upgrading or downgrading Hydrolix can result in database schema inconsistencies and cluster instability. Always upgrade or downgrade sequentially through each minor version.

Example:
Upgrade from 5.7.9 → 5.8.6 → 5.9.5, not 5.7.9 → 5.9.5.

Changelog

Bug fixes

Config API

• Fixed the Config API to allow primary columns to be marked as virtual: true. Earlier, the API silently set virtual: false on all primary columns and rejected explicit virtual: true on them.

Cluster operations

• Added the prometheus_extra_args operator tunable, which passes additional CLI flags to the Prometheus binary. Set it to a list of strings such as --storage.tsdb.max-block-duration=2h. Flags that conflict with Prometheus's built-in defaults (such as --config.file and --storage.tsdb.path) override those defaults rather than duplicating them.

Core

• Added tunable json_datatype_enabled with default setting off for production environments. Enable this tunable to experiment with the beta JSON column data type. This isn't recommended for production environments.
