New features:
- Added 'podVolumeClaimTemplate' and 'logVolumeClaimTemplate' in order to map data and logs separately. Old syntax is deprecated but supported.
- Sidecar clickhouse-logs container to view logs if persistent volume is used
- Significantly cleaned up templates model and 'useTemplates' extension
- new system_replicas_is_session_expired monitoring metric (#187 by @teralype)
Bug fixes:
- Fixed bug with installation name being truncated to 15 chars. The current limit is 60 chars. Cluster name is limited to 15.
- General stability improvements and fixes for corner cases
Upgrade notes:
- There were changes in ClickHouseInstallation CRD, so it is recommended to remove and re-install the operator. Existing ClickHouse clusters will be picked up automatically.
- IMPORTANT: If you upgrade operator from 0.6.0 or earlier to 0.7.0 please make sure your ClickHouseInstallation name is shorter than 15 symbols. Otherwise DO NOT UPGRADE an operator.
