-----------------------------------
Summary: Streams integration tests should not use commit interval
of 1
Key: KAFKA-4359
URL: https://issues.apache.org/jira/browse/KAFKA-4359
Project: Kafka
Issue Type: Improvement
Components: streams
Affects Versions: 0.10.1.1
Reporter: Eno Thereska
Assignee: Eno Thereska
Fix For: 0.10.1.1
Several streams integration tests use two cache sizes, 0 and 10MB. However,
when they use 10MB, they still use a very small commit interval (1ms). That
leads to two problems:1) a small commit interval often has the same effect as
having the cache size be 0, and 2) a small commit interval is not exactly the
same as the cache size being 0 and in some cases there is deduplication. This
leads to the tests failing, since they don't expect deduplication.
To solve this issue, look at KStreamAggregationDedupIntegrationTest and
KStreamAggregationIntegrationTest. If you want to test dedup, it would be
necessary to create another file.
Several tests need this cleanup.
