Percona ClusterSync for MongoDB (PCSM) is a tool designed to replicate data from one MongoDB cluster to another with minimal downtime. It supports both initial data cloning and continuous change replication using MongoDB change streams, making it ideal for migrations, upgrades, and cross‑cluster synchronization. PCSM allows selective replication of databases and collections, automatically manages indexes on the target cluster, and simplifies complex data‑movement workflows. This category is dedicated to discussions, troubleshooting, and best practices for using PCSM in real environments. We invite you to try the tool, share your experiences, and ask any questions as you explore its capabilities.
