When I execute this (select count(*) from userdetails

Answer 1

I'm using Cassandra 3.4 and cqlsh to get record counts. It appears that there has been a code change in 3.4. cqlsh just calls cqlsh.py. Inside of cqlsh.py there is a DEFAULT_REQUEST_TIMEOUT_SECONDS variable that defaults to 10 (seconds). I changed it to 3600 (1 hour) and now my SELECT count(*) queries work.
