Work Description: script3r commented on issue #5112: [BEAM-4049] Improve
CassandraIO write throughput by performing async queries
URL: https://github.com/apache/beam/pull/5112#issuecomment-427648485
Yeah, I can confirm that the issue is persists and that it is unrelated to
version mismatch.
I also rolled back to 2.3.0 and it works. I suspect the issue is associated
with this commit removing listenable future from guava during packaging.
I’ll take a stab at fixing this issue within this week if the committer
doesn’t get to it by then.

> The CassandraIO currently uses the mapper to perform writes in a synchronous
> fashion.
> This implies that writes are serialized and is a very suboptimal way of
> writing to Cassandra.
> The IO should use the saveAsync() method instead of save() and should wait
> for completion each time 100 queries are in flight, in order to avoid
> overwhelming clusters.
