Replicator
Replicator is a toolkit for consuming a variety of logical replication feeds and inserting the data into a destination CockroachDB cluster.
This is a prototype and is not supported by Cockroach Labs except by prior arrangement.
Use of this tool is entirely at your own risk and Cockroach Labs makes no guarantees or warranties about its operation.
