---------------------------------
Summary: Renaming the time interval window for better understanding
Key: KAFKA-13145
URL: https://issues.apache.org/jira/browse/KAFKA-13145
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: Luke Chen
Assignee: Luke Chen
I have another thought, which is to rename the time interval related windows.
Currently, we have 3 types of time interval window:
{{TimeWindow}} -> to have {{[start,end)}} time interval
{{SessionWindow}} -> to have {{[start,end]}} time interval
{{UnlimitedWindow}} -> to have {{[start, MAX_VALUE)}} time interval
I think the name {{SessionWindow}} is definitely not good here, especially we
want to use it in {{SlidingWindows}} now, although it is only used for
{{SessionWindows}} before. We should name them with time interval meaning, not
the streaming window functions meaning. {{}}Because these 3 window types are
internal use only, it is safe to rename them.
{{TimeWindow}} --> {{InclusiveExclusiveWindow}}
{{SessionWindow}} / {{SlidingWindow}} --> {{InclusiveInclusiveWindow}}
{{UnlimitedWindow}} --> {{InclusiveUnboundedWindow}}
