Setting up SuperDuperDB as a change-data-capture daemon

info

This functionality is currently for MongoDB only

Setting-up SuperDuperDB as a change-data-capture daemon, is a simple call:

db.cdc.listen()

... or

superduperdb cdc

When superduperdb is configured in this way, this daemon handles all inserts to SuperDuperDB, therefore, if superduperdb is run in another process or service, it's important to configure the existence of the daemon:

from superduperdb import CFG

CFG.cluster.cdc = True

Now that the daemon is running, even when data is inserted using a different client, such as the native pymongo.MongoClient client, then Listener outputs are still created on those inputs.
