Cassandra devs,
I have a question about the implementation of
PartitionUpdate.singleRowUpdate(), in particular the choice to use
EncodingStats.NO_STATS when building the resulting PartitionUpdate. Is
there a functional reason for that -- i.e., is it safe to modify it to
use an EncodingStats built

Cassandra devs,
We use workflows in some of our clusters (running 3.0.15) that involve
"SELECT DISTINCT key FROM..."-style queries. For some tables, we
observed extremely poor performance under light load (i.e., a small
number of rows per second and frequent timeouts), which we eventually
traced

Hi folks,
I have a question about a design choice on how expiring cells are
reconciled with tombstones. For two cells with the same timestamp, if
one is expiring and one is a tombstone, Cassandra *always* prefers the
tombstone. This matches its behavior for normal/non-expiring cells, but
