molt replicator

Continuous change-data-capture (CDC) replication from source databases to CockroachDB. Run after molt fetch completes the initial bulk load.

Important: replicator is a separate binary from molt. It is not invoked by molt fetch. The data-load-and-replication mode in molt fetch is deprecated — use replicator directly instead.

Replicator reads changes from the source, buffers them in a staging schema on the target CRDB cluster, and applies them to the target tables.
