BUT... The use-case for that has pretty much evaporated since the fastest way of bulk loading data (in my opinion 🙂) is using the DataStax Bulk Loader [1]. It's the fastest because: To be clear: CQLSSTableWriter and sstableloader are the canonical way to write and bulk load SSTables, for the Apache Cassandra project. * you don't need to write code to use it * you can load any data in CSV or JSON format * you directly load to your cluster bypassing the sstableloader step completely Check it out and see if it meets your requirements. I think you'll find it will save you a lot of time in the long run. Cheers! [1] https://www.datastax.com/blog/2019/12/tools-for-apache-cassandra GOT QUESTIONS?
