operator chaining?
Hi,
No, I think you are right, I forgot about the broadcasting requirement.

Hi,
Broadcasting will brake an operator chain. However my best guess is that Kafka
source will be still a performance bottleneck

source will be still a performance bottleneck in your job. Also Network
exchanges add some measurable overhead only if your records are very
lightweight and easy to process (for example if you are using RocksDB
Hi all,
My flink job has dynamic schema of data, so I want to consume a schema kafka

For example, the two streams just like this:
