Hi Looking at the production readiness <https://ci.apache.org/projects/flink/flink-docs-stable/ops/production_ready.html#set-maximum-parallelism-for-operators-explicitly> checklist - is there any rule of thumb to determine the maximum parallelism ? we have a stateful pipeline with high throughput (4k requests/sec) running on google cloud (yarn) . I understood that if we are not setting it the default setting is 128 but it can change in the future but if we set it, it cannot be change later - correct ?
Is there any way to get info on state (RocksDB) e.g number of keys , or list of keys ? Regards Avi
