Hello, can you please answer my question: is it possible to delete keyed state by key?

i think this will answer your question https://nightlies.apache.org/flink/flink-docs-release-1.13/docs/dev/datastream/fault-tolerance/state/#:~:text=All%20types%20of%20state%20also%20have%20a%20method%20clear()%20that%20clears%20the%20state%20for%20the%20currently%20active%20key%2C%20i.e.%20the%20key%20of%20the%20input%20element.

thanks)

for ValueState & ListState -> clear() and update() MapState -> clear() and remove()
