Module vector_data 

VectorData value encoding/decoding.

Stores all data for a single vector: external ID, embedding vector, and metadata.

Storage Design

Vectors are stored individually (one record per vector) rather than batched together. This enables:

• Efficient point lookups: Load a single vector without reading neighbors
• Partial loading: During filtered search, only load vectors that pass filters
• Independent updates: Upsert/delete individual vectors without rewriting batches

Unified Storage

Vector data, metadata, and external ID are stored together in a single record. The vector is stored as a special field with tag 0xff (255) alongside metadata fields.

Dimensionality

The vector length is not stored in the value—it’s obtained from CollectionMeta. All vectors in a collection must have the same dimensionality.

Structs

Field

A metadata field with name and value.

VectorDataValue

VectorData value storing the external ID, embedding vector, and metadata.
