Hi again,

thanks for trying to make it work. Apologies that our Java experts are currently on vacation, but please don’t fret – we’ll see what we can do for you.

May we ask if you are strictly bound to use Kafka for relaying that data from MongoDB? Is there a chance you could directly tap into it? As you can see at [Using CrateDB Toolkit to sync MongoDB with CrateDB](https://community.cratedb.com/t/using-cratedb-toolkit-to-sync-mongodb-with-cratedb/2062), it is much more likely to make a difference faster on such teething problems.

Please let us know if using different technologies could be an option for you.

With kind regards,  
Andreas.
