Frequently asked questions

Is Meltano's MongoDB support real CDC?

Yes — tap-mongodb supports log-based replication via MongoDB's Change Streams API, a genuine capability, not just polling.

Why choose a managed tool like NoSQLSync instead?

If you don't want to operate the pipeline yourself — sizing, monitoring, schema evolution, error handling — NoSQLSync is the managed alternative to assembling and running Meltano's taps and targets yourself.
