@embedding

We’re overhauling Dgraph’s docs to make them clearer and more approachable. If you notice any issues during this transition or have suggestions, please let us know.

A Float array can be used as a vector using @embedding directive. It denotes a vector of floating point numbers, i.e an ordered array of float32.

The embeddings can be defined on one or more predicates of a type and they’re generated using suitable machine learning models.

This directive is used in conjunction with @search directive to declare the Hierarchical Navigable Small World (HNSW) index. For more information see: @search directive for vector embeddings.
