Detailed requirement

Bug fix requirements

The current implementation suffers from a bug that when the processor is brought down for some time, messages received during that time won’t be processed when the processor is restarted.

The consumer commits the offset to zookeeper but when the processor starts it picks the latest offset instead of the committed offset.

This needs to be fixed in all the processors mentioned in the code access section.

 

Feel free to ask on the challenge forum!
