Hi all:
When I broadcast the big config stream,every parallel instance should store
the data, cause waste of the momery and time. Is there some method to make the
slots to share the big data structure within the taskmanager？
Here is the doc:
By adjusting the number of task slots, users can define how subtasks are
isolated from each other. Having one slot per TaskManager means each task group
runs in a separate JVM (which can be started in a separate container, for
example). Having multiple slots means more subtasks share the same JVM. Tasks
in the same JVM share TCP connections (via multiplexing) and heartbeat
messages. They may also share data sets and data structures, thus reducing the
per-task overhead.
