I’m running a lagom service on Kubernetes. In the Kubernetes Cluster i have 3 Pods of Cassandra up and running.
Here is how i configured Cassandra in my lagom service:
cassandra-journal.keyspace=authenticationservice
cassandra-snapshot-store.keyspace=authenticationservice
lagom.persistence.read-side.cassandra.keyspace=authenticationservice
lagom.persistence.read-side.cassandra.replication-factor=3
lagom.persistence.read-side.cassandra.write-consistency=“ONE”
lagom.persistence.read-side.cassandra.read-consistency=“ONE”
lagom.persistence.read-side.cassandra.log-queries=true
lagom.persistence.read-side.cassandra.max-result-size=1000
Somehow this configuration doesn’t seem to be correct. Today Morning after one of the cassandra pod restarted, my lagom service what not able to connect to cassandra anymore, i started getting following error:
Caused by: com.datastax.driver.core.exceptions.UnavailableException: Not enough replicas available for query at consistency ONE (1 required but only 0 alive)

Can someone please help me to find the right way to configure Cassandra in my service, what are the configuration i have to properly configure?
Thank you
