> 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.
