How to Reset the Offsets of a Consumer Group?

• Stop the applications running on this Consumer Group, otherwise the buttons won't be accessible. Don't worry, we clearly state that the group must be stopped before acting on it 😉.

• Click on "Change offsets" then configure the strategy to how reset the offsets:

  • which topic: a consumer group can subscribe to multiple topics

  • which partition: sometimes you know exactly which message is stuck!

  • the new offset. It's computed automatically according to a few methods:

    • Earliest: start from the beginning, reprocess everything!

    • Latest: start from the end, ignore all the existing records

    • Latest minus X: just reprocess the latest X records

    • Current offset + X: to jump over some records

    • Specific Datetime: when you know when your app started to crash

    • Current time minus X seconds: just the latest records in time

• When you change the strategy, Conduktor automatically recomputes the New Offset (right column).

• Click on CHANGE OFFSETS (X) when you're happy with the proposal

  • X is the number of changes

• Don't forget to restart your application! 💪
