@je-ik `maxParallelism` beyond the number of partitions in Kafka, you're basically giving workers extra splits that they don't need for that Kafka topic. This means each worker ends up using more threads than necessary. And when you've got a bunch of KafkaIO pipelines doing this, it eats up more memory and makes the checkpoints bigger. Bigger checkpoints can slow down how often you can do them, which isn't great for keeping things running smoothly. Is there any benefit to set bigger than partition count ? -- This is an automated message from the Apache Git Service.
