* `timeout` (default = 10s): The Cassandra server connection timeout
* `keyspace` (default = otel): The keyspace name.
* `trace_table` (default = otel\_spans): The table name for traces.
* `replication` (default = class: SimpleStrategy, replication\_factor: 1): The strategy of
  replication. [https://cassandra.apache.org/doc/4.1/cassandra/architecture/dynamo.html#replication-strategy](https://cassandra.apache.org/doc/4.1/cassandra/architecture/dynamo.html#replication-strategy)
