Percona Operator for MongoDB 1.23.0 introduces three major features: ClusterSync (PCSM), vector search, and PVC snapshot backups. ClusterSync enables live migration from hosted MongoDB services like Atlas by cloning data and tracking change streams, allowing short cutover windows instead of long maintenance outages. Vector search (tech preview) integrates semantic querying directly into Percona Server for MongoDB via a managed mongot process, eliminating the need for a separate search engine. PVC snapshot backups use the Kubernetes VolumeSnapshot API to take storage-layer snapshots that complete in seconds regardless of database size. The release also adds RKE2 support and full ARM64 images. Both vector search and PVC snapshot backups are tech previews not yet recommended for production.
