Hi:
I am working on a project and need to save MapState in a process function and
register a timer to check for updates. I wanted to find out if it is safe to
access and modify the state in the processElement function as well as the time
onTimer methods.
The example
https://ci.apache.org/projects/flink/flink-docs-release-1.3/dev/stream/process_function.html
use ValueState and does not use synchronization. Is it because processElement
and onTimer are executed in the same thread and so are thread safe ?
Also, I could not find any thread safety documentation about MapState.
Thanks.
