Tri Nguyen created CASSANDRA-16747: -------------------------------------- Summary: Block creating keyspace with RF > Cassandra node count Key: CASSANDRA-16747 URL: https://issues.apache.org/jira/browse/CASSANDRA-16747 Project: Cassandra Issue Type: Improvement Components: Cluster/Schema Reporter: Tri Nguyen
Using Cassandra 3.11.10, 3 nodes cluster Cassandra allows to create a keyspace having `replication_factor` greater than the number of available nodes. {code:java} -- successfully created Keyspace with RF = 3 > node count = 3 CREATE KEYSPACE mykeyspace WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 5 }; {code} >From [this >discussion|https://community.datastax.com/questions/11623/create-keyspace-with-rf-physical-cassandra-node-co.html] > on community.datastax.com. It appears that this would lead to serious >operational problems. Would it be OK to improve the `CREATE KEYSPACE` to block (or display warning) when attempting to set `replication_factor` > node count? -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
