dracarys09 opened a new pull request, #86:
URL: https://github.com/apache/cassandra-easy-stress/pull/86
Summary of the changes
- Add VectorSearch workload for benchmarking Cassandra 5.0+ vector search
(ANN) capabilities
- Support both synthetic random vectors and realistic datasets via HDF5
files (SIFT, GloVe, etc.)
- Implement recall@K calculation with ground truth comparison for
measuring search quality
- Add configurable similarity functions (COSINE, EUCLIDEAN, DOT_PRODUCT)
and vector dimensions
Testing
- Run ./gradlew test --tests
"org.apache.cassandra.easystress.workloads.VectorSearchTest"
- Verify workload runs against a Cassandra 5.0+ cluster with random vectors
- Test with an HDF5 dataset (e.g., sift-128-euclidean.hdf5) and verify
recall metrics are logged
- Confirm ktlint passes: ./gradlew ktlintCheck
