Hello. For unit test purposes, I have a single node Cassandra cluster. I need to drop and re-create several keyspaces between each test iteration. This process takes approximately 10 seconds for a single node installation.
Can you recommend any tricks or recipes to reduce the time required for such operations and/or for "Waiting for schema agreement" to complete? regards, - Joe N. $ time ./setupDB.sh Deleteing cassandra keyspaces Connected to: "Foo" on 127.0.0.1/9160 ed9c7fc0-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster ee8c36f0-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster eeb14b20-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster Insert data Creating cassandra keyspaces Connected to: "Foo" on 127.0.0.1/9160 ef1a6d30-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster Authenticated to keyspace: Bars ef4af310-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster ef9bab20-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster efbceec0-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster f00e4310-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster f0589280-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster f0821380-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster f0c44ca0-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster Authenticated to keyspace: Baz f121d5f0-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster f1619e10-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster f18b4620-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster Authenticated to keyspace: Buz f1debd50-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster f20690a0-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster f25043d0-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster f29a1e10-ee91-11e0-0000-534d24a6e7f7 Waiting for schema agreement... ... schemas agree across the cluster Inserting data in cassandra Connected to: "Foo" on 127.0.0.1/9160 Authenticated to keyspace: Boo Value inserted.
