Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If engineers manually select indexing algorithms using their expertise, then the system can achieve optimized performance, but the process requires significant human input and guesswork
Solution Approach 1:
The system automatically selects indexing algorithms by performing benchmarking tests itself, without requiring engineers to manually choose algorithms based on their expertise. The system generates algorithm scores through automated testing and selects the optimal algorithm based on these scores, making the selection process self-service rather than dependent on human intervention.
2Adaptability or versatility
If engineers manually select indexing algorithms, then customization to specific use cases is possible, but the process is improper for many use cases due to lack of domain expertise
Solution Approach 1:
The system performs preliminary benchmarking tests on multiple candidate indexing algorithms before deployment to determine which algorithm is most suitable for the specific use case. By pre-testing algorithms with representative data and workloads, the system identifies the optimal algorithm for each specific application scenario, ensuring both adaptability and reliability.
3Ease of manufacture
If traditional embedding databases are used without automated algorithm selection, then implementation is simpler, but lookup efficiency and accuracy are suboptimal
Solution Approach 1:
The system changes the parameter of algorithm selection from manual engineer choice to automated benchmarking-based selection. By implementing automated testing that evaluates multiple indexing algorithms under specific workload conditions, the system transforms the database setup process while significantly improving lookup efficiency and accuracy through data-driven algorithm selection.

AI summary
An online system uses benchmarking tests to identify indexing algorithms for an embedding database. To perform these benchmarking tests, the online system receives a set of parameters for configuring an embedding database. For example, the parameters may include a performance parameter and a latency parameter. The online system generates algorithm scores for a set of candidate indexing algorithms based on the parameters. Specifically, the online system tests each of the candidate indexing algorithms by generating a testing database based on a subset of the entries for the full database and by performing benchmarking tests on the testing database. The online system uses these tests to compute performance metrics for each candidate indexing algorithm and uses those performance metrics to compute an algorithm score for each indexing algorithm. The online system uses the computed algorithm scores to select an indexing algorithm for the embedding database.
