Description

While running a job, without fault tolerance, producing data to Kafka, the job failed due to "Batch Expired exception". I tried to increase the "request.timeout.ms" and "max.block.ms" to 60000 instead of 30000 but still the same problem. The only way to ride on this problem is using snapshotting.
