Running CQL benchmarks

Two nosqlbench tests will be executed on each benchmarked Cloud vendor: the first focuses on throughput, the second on latency.

On the baseline setup, the benchmarks need to be manually launched.

For Kubernetes cloud providers: the benchmarks can be executed on a running Kubernetes cluster with K8ssandra previously installed, by simply running the following shared script:

./shared/run-cql-benchmarks.sh

Unfortunately, it's not possible to download the benchmark results in a vendor-agnostic way, so each vendor will have its own method for downloading them:

• EKS
• GKE
• AKS

Benchmark characteristics

Throughput benchmark characteristics:

• No rate limiting with 100M cycles and up to 300 in flight async queries, 50% writes and 50% reads at LOCAL_QUORUM, using the cql-tabular2 profile with partitions of 5k rows.

See YAML Job definition here.

Latency benchmark characteristics:

• Rate limited at 8k ops/s with 50M cycles and up to 300 in flight async queries, 50% writes and 50% reads at LOCAL_QUORUM, using the cql-tabular2 profile with partitions of 5k rows.
