Well, that's a long story. In general, there are 2 steps.
1. *Which operators are deployed in the same slot?* Operators are first
*chained*[1] together, then a *slot sharing strategy*[2] is applied by
default.
2. *Which task managers are slots allocated from?*
1. For active deplo
Thanks.
When the program starts, how is each operator allocated in taskmanager?
For example, if I have 2 taskmanagers and 10 operators, 9 operators are
allocated to tm-A and the remaining one is placed in tm-B, the utilization
of resources will be very low.

Hi,
For a complex streaming job, is there any way to tilt the memory towards
> stateful operators?
If streaming jobs are interested, the quick answer is no. Memory is fetched
on demand for all operators.
Currently, only managed memory for batch jobs are pre-planned for each
operator.
Thank you~
