Upgrade Notes & Compatibility Warnings

  • The minimum supported version of Solr has been set to Solr 8.11
  • The minimum Kubernetes version supported is now v1.22
  • Please refer to the documentation for a complete list of upgrade warnings

Improvements

  • Solr 8.11 features are now supported by default, such as maxBooleanClauses, metrics disabling, health endpoint for readinessCheck
  • Rolling Updates for SolrClouds using ephemeral storage are now safer and replicas are balanced at the end of the operation to ensure optimal resource utilization.
    • Replica balancing is only supported when Solr 9.3+ is used.

New Features

  • Managed scale up and scale down are now supported for SolrClouds.
    • By default, when scaling down a SolrCloud, replicas will be migrated off Pods before they are deleted.
    • By default, when scaling up a SolrCloud, replicas will be balanced across all Pods after the SolrCloud has been scaled up. (Only supported for Solr 9.3+)
  • Keystore/Truststore passwords can be explicitly set in the SolrCloud CRD for mountedDir SSL. This enables the use of the CertManager CSI Driver with Solr.

Bug Fixes

  • SSL bugs with Solr 9 have been fixed, and v0.8.0 will successfully support SSL for Solr 8.11 and 9.4+
