## Features

* **Data clone**: Transfer existing data from a source MongoDB to a target MongoDB deployment.
* **Real-time replication**: {{pcsm.full_name}} uses MongoDB [change streams :octicons-link-external-16:](https://mongodb.com/docs/manual/changeStreams/) to track changes in your source cluster and replicate them to target in real time.
* **Namespace filtering**: Specify which databases and collections to include or exclude.
* **Automatic index management**: Ensure necessary indexes are created on the target.
* **HTTP API**: Start, finalize, pause, resume, and check replication status via HTTP endpoints.
