Check the offsets of the records for each partition are not "much older" than the records that we have seen thus far for the partition.
Check the offsets of the records for each partition are not "much older" than the records that we have seen thus far for the partition. Records/partitions that appear to have rewound to a much earlier time (as defined by the configured threshold) are dropped and the consumer is seeked back to the last safe offset for that partition - the last committed offset for the partition. Records that are newer - or within the rewind threshold - are passed through.
