Hi Kushagra, Thanks for replying!
Yes, we are depending on oplog. We are saving it in our memory and reusing it incase of crashing to start fetching from the time where it was left. The issue got resolved after creating new that key and restarting the service.
We didn’t have any changes in the recent times. But all of sudden it started failing. We are using this as a producer to replicate the data and it will be used by the consumers via kafka. The data modification happens only in the consumer’s side but not at the producer.
Please check and let me understand on the issue.
Thanks,
Bala
