Re: [DISCUSS] CEP-28: Reading and Writing Cassandra Data with Spark Bulk Analytics

Hi folks, Great stuff thanks for sharing. The performance numbers I've seen so far are for the sidecar streaming sstables (seems like this is just network bound?). What kind of perf are you seeing at the Spark executors (at the per task level)? --Seb On Mon, May 1, 2023 at 3:50 PM Dinesh Joshi
