DBClient Engine: Vector
Covered Testers and Aliases
| Engine | Tester | Aliases |
|---|
| Milvus | MilvusTester.java | milvus |
| Qdrant | QdrantTester.java | qdrant |
Key Dependencies (build.gradle)
// Milvus
implementation 'io.milvus:milvus-sdk-java:2.5.9'
implementation 'io.perfmark:perfmark-api:0.26.0'
// Qdrant
implementation 'io.qdrant:client:1.12.0'
implementation 'org.apache.httpcomponents:httpclient:4.5.13'
implementation 'com.fasterxml.jackson.core:jackson-databind:2.13.0'
Key Concerns
- Vector databases use concepts such as dimension, collection, and distance metric; the
query parameter format is not SQL.
VectorGenerator (src/main/java/com/apecloud/dbtester/commons/VectorGenerator.java) is used to generate test vectors.- Qdrant result formatting has a special branch in
TestExecutor.formatQueryResult().
Maintenance Notes
- Vector SDKs evolve quickly; ensure server and client version compatibility.
- When adding a new vector engine, check whether
VectorGenerator needs to be extended.
