We have a open JIRA in Flink to start a "streaming only" mode, which starts
up Flink in an streaming optimized mode.
For now, you can set the following configuration values in the
conf/flink-conf.yaml to achieve a similar effect:
- `taskmanager.memory.fraction`: This fraction describes the division
between managed and unmanaged heap space. Flink batch is using managed memory
for its operations, flink streaming uses unmanaged memory only. By default the
value is set to 0.7, which leaves not much memory for streaming. I would
recommend setting the value to `0.001` ;)
- `taskmanager.heap.mb`: Thats an integer specifying the task manager's
heap size. By default its set to 512. I suspect your machine has more memory.
