Stefania commented on CASSANDRA-12014:
--------------------------------------
Right, we don't need to scan the entire memtable, the first 50 keys should be
enough for an estimate. The alternative is to keep track of the total size of
keys with an atomic long but I thought that was a bit of an overkill.
> IndexSummary > 2G causes an assertion error
