klion26 commented on issue #6558: [FLINK-9116] Introduce getAll and removeAll
for MapState
URL: https://github.com/apache/flink/pull/6558#issuecomment-414117596
Hi, @StefanRRichter If I use a field to store the user map in Heap backend,
I will override the `AbstractHeapState#clear` to update the field, so I'll
change `public final void clear()` in AbstractHeapState to `public void
clear()` , and change the `getUserMap` in Heap backend such as `if (userMaps ==
null) {
userMaps = stateTable.get(currentNamespace);
} else if (stateTable.keyContext.getCurrentKey() != currentKey)
{
userMaps = stateTable.get(currentNamespace);
currentKey = stateTable.keyContext.getCurrentKey();
}
return userMaps;` is this ok?
