Hi all. Is it possible to set up init script when we start Flink SQL Gateway? https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/sql-gateway/rest/#rest-api. I see that we can do that with Flink sql client, but not sure about Flink SQL Gateway. My goal is to init and create kafka topic for testing so that people does not need to do that everytime.
