This seems to be the correct behavior. An update refreshes the TTL, as it does in memcache for example. Yet, what I do not know is whether this behavior can be changed somehow to let the initial TTL, this might be useful on some use cases.

Apparently when I update a column using CQL that already has a TTL, it resets the TTL to null, so if there was already a TTL for all columns that I inserted part of a composite column set, this specific column that I updated will not expire while the others are are getting expired. Is it how it is expected to work or it is a bug?

Thanks in advance
