I am using Cassandra 2.1.13 which has all the latest DTCS fixes (it does STCS within the DTCS windows). It also introduced a field called MAX_WINDOW_SIZE which defaults to one day.
So in my data folders, I may see SS Tables that span beyond a day (generated through old data through repairs or commit logs), but whenever I see a message in logs "Compacted Foo" (meaning the SS Table under question was definitely a result of compaction), the "Foo" SS Table should never have data beyond a day. Is this understanding accurate ? If we have issues with repairs pulling in old data, should MAX_WINDOW_SIZE instead be set to a larger value so that we don't run the risk of too many SS Tables lying around and never getting compacted ?
