Unique: Implements columnar attribute storage with in-memory indexing for O(1) filtering and sorting, supporting range queries and faceted search without decompressing inverted indexes. Attributes can be imported from other document types via reference fields for efficient joins.

vs others: Faster than Elasticsearch for numeric filtering because attributes are stored in dense columnar format and loaded into memory, enabling sub-millisecond range queries without inverted index decompression.
