I'm trying to simulate an issue that I am encountering in production due to a Redis master/slave replication lag (delay). Is there a way to introduce artificial lag instead of bombarding the master and hence hoping for a replication lag (delay)?

You can add a delay at the packet level using the tc command to configure network traffic control in the Linux kernel. In the simplest implementation, you would delay all traffic from the master to slave. See https://stackoverflow.com/a/615757/11146001 for a related use case.

  • Thanks for the note. I was never thinking of causing delay at a network level - but it is worth trying. Will keep you posted. – user22648 Mar 05 '19 at 02:31
