Flink jobs scale from 4k+ buckets and tiny per-bucket streams to single-bucket batch loads of 150M+ messages by replacing the default sink with a two-phase S3 sink that removes a 3s per-message existence check, keeps in-flight data in state with a size threshold, switches renames to an AWS S3 client and parallelizes commits to restore throughput and exactly-once. Job completion for 12-hour batches is signaled only after checkpoint-confirmed commits via a secondary stats flow. Testing uses a message firehose, local Kafka and a performance-evaluator subproject.
