- Variant Functions 11403
- This section describes functions that operate on the VARIANT type . New Most variant_* functions were introduced in DuckDB 2.0. The variant_extract , variant_normalize and variant_typeof functions were already available in DuckDB 1.5. Name

- Vector Similarity Search Extension 9598
- The vss extension is an experimental extension for DuckDB that adds indexing support to accelerate vector similarity search queries using DuckDB's new fixed-size ARRAY type. See the announcement blog post and the “What's New in the Vector S

- JSON Processing Functions 6882
- JSON Extraction Functions There are two extraction functions, which have their respective operators. The operators can only be used if the string is stored as the JSON logical type. These functions support the same two location notations as

If path is a LIST , the result will be LIST of array lengths. json_contains(json_haystack, json_needle) Returns true if json_needle is contained in json_haystack . Both parameters are of JSON type, but json_needl... - https://man.mtool.work/duckdb/2.0/data/json/json_functions.html
