Development with AWS Services
A Lambda function consumes a Kinesis data stream that has 4 shards. Iterator age keeps growing, and each record takes a long time to process. The developer wants more concurrent processing without resharding, while keeping order for each partition key. What should the developer change?
Increase the stream's retention period to 7 days.
Increase the ParallelizationFactor on the event source mapping.
Decrease the event source mapping's batch size to 1.
Enable enhanced fan-out for an additional stream consumer.
B
ParallelizationFactor (1 to 10) lets Lambda process up to 10 batches from each shard at the same time, while records with the same partition key are still processed in order. Longer retention only keeps data longer, a batch size of 1 adds overhead without adding concurrency, and enhanced fan-out improves read throughput rather than invocations per shard.
