Guozhang Wang commented on KAFKA-6629:
--------------------------------------
Hello Jagadesh,
In SegmentedCacheFunctionTest.java, WindowKeySchema is used to generate the
bytes format for cached key etc; this effectively is testing the time window
serdes (you can look into WindowKeySchema's internal implementation). However
this test code does not use SessionKeySchema which is effectively using session
window serdes.
The goal is to make this test a parameterized one (Junit supports that), to
have a schema that can be configured to be both WindowKeySchema and
SessionKeySchema, and run all the test cases for both of them.
> SegmentedCacheFunctionTest does not cover session window serdes

> The SegmentedCacheFunctionTest.java only covers time window serdes, but not
> session window serdes. We should fill in this coverage gap.
