DataStax Enterprise 6.0 has a new bulk loader tool. DSE is a commercial product, but maybe your needs are worth the investigation.

Although it can be run in parallel on different nodes I don’t believe it to be as fault tolerant. If you have to do it continuously I would even think about leveraging Kafka as the transport layer and using Kafka Connect. It brings other tooling to get data into Cassandra from a variety of sources.

We want that data to be transferred to cassandra tables. What are some of the high performance ETL options for transferring data between hive or presto into cassandra? Also does anybody have any performance numbers comparing - loading data from S3 to cassandra using SStableloader - and loading data from S3 to cassandra using other means (like spark-api)?
