No more documents in tailed cursor #14

Closed gdevdeiv closed 7 years ago

After a clean installation of momy, and having to set the "timestamp" field of the "mongo_to_mysql" table to something else than 0, I'm stuck getting this error.

ubuntu:~$ momy

Fixed it. My problem was the mongod setup, as I couldn't get the ReplicaSet to work with the given information at README.md.

As a suggestion, it might be a great idea, mostly for beginners, to add more information about how to setup the MongoDB server.
