MariaDB innovation: vector index performance

Automated excerpt

Last year I shared many posts documenting MariaDB performance for vector search using ann-benchmarks. Performance was great in MariaDB 11 and this blog post explains that it is even better in MariaDB 12. For Postgres tests were run with and without halfvec (float16). I had ps and vmstat running during the benchmark and confirmed there weren't storage reads as the table and index were cached by MariaDB and Postgres. The command lines to run the benchmark using my helper scripts are: bash rall. batch. sh v1 dbpedia-openai-100k-angular c32r128 bash rall. batch. sh v1 dbpedia-openai-500k-angular c32r128 bash rall. batch.
