What version of Cassandra are you using?

4.1.3 or 5.0

What version of Gocql are you using?

1.6.0

What version of Go are you using?

1.21.1

What did you do?

• I start local cassandra in docker with docker run --rm --name=cassandra -p 9042:9042 cassandra:4.1.3
• I run this program - https://github.com/isopov/gocqltest/blob/main/main.go

What did you expect to see?

I expect the program to finish successfully.

What did you see instead?

I see errors

gocql: no hosts available in the pool
gocql: no streams available on connection
gocql: no hosts available in the pool
gocql: no streams available on connection
gocql: no hosts available in the pool
gocql: no hosts available in the pool

or

gocql: no hosts available in the pool
gocql: no hosts available in the pool

Note: changing workers const to 50_000 allows the program to finish gracefully (increasing queries const is possible also - program will work minutes instead of seconds but still will finish gracefully with 50_000 workers)
