See the announcement blog post and the “What's New in the Vector S ... imilarity Search Extension?” post . Usage To create a new HNSW (Hierarchical Navigable Small Worlds) index on a table with an ARRAY column, use the CREATE INDEX statement with the USING ... HNSW clause. For example: INSTALL AND LOAD vss; CREATE TABLE my_vector_table (vec FLOAT[3]); INSERT INTO my_vector_table SELECT ... array_value(a, b, c) FROM range(1, 10) ra(a), range(1, 10) rb(b), range(1, 10) rc(c); CREATE INDEX my_hnsw_index ON my_vector_table USING HNSW (vec); The index will then be used to accelerate queries that use an ORDER BY clause e ...; https://man.mtool.work/duckdb/2.0/core_extensions/vss.html
