This adds some testing tools for verifying vector recall and latency directly without having to spin up an entire ES node and running a rally track. Its pretty barebones and takes inspiration from lucene-util, but I wanted access to our own formats and tooling to make our lives easier. Here is an example config file. This will build the initial index, run queries at num_candidates: 50, then again at num_candidates 100 (without reindexing, and re-using the cached nearest neighbors). ``` [{ "doc_vectors" : "path", "query_vectors" : "path", "num_docs" : 10000, "num_queries" : 10, "index_type" : "hnsw", "num_candidates" : 50, "k" : 10, "hnsw_m" : 16, "hnsw_ef_construction" : 200, "index_threads" : 4, "reindex" : true, "force_merge" : false, "vector_space" : "maximum_inner_product", "dimensions" : 768 }, { "doc_vectors" : "path", "query_vectors" : "path", "num_docs" : 10000, "num_queries" : 10, "index_type" : "hnsw", "num_candidates" : 100, "k" : 10, "hnsw_m" : 16, "hnsw_ef_construction" : 200, "vector_space" : "maximum_inner_product", "dimensions" : 768 } ] ``` To execute: ``` ./gradlew :qa:vector:checkVec --args="/Path/to/knn_tester_config.json" ``` Calling `./gradlew :qa:vector:checkVecHelp` gives some guidance on how to use it, additionally providing a way to run it via java directly (useful to bypass gradlew guff). |
