Vector

Redis implementation of vector similarity search capability.

This module provides a Redis implementation of the VectorCapability protocol using RedisVL AsyncSearchIndex for vector storage and similarity search.

`RedisVectorCapability(index_name, client, em_invoker, encryption=None, default_batch_size=None)`

Redis implementation of VectorCapability protocol.

This class provides vector similarity search operations using RedisVL AsyncSearchIndex for vector storage and retrieval.

Attributes:

Name	Type	Description
`index_name`	`str`	Name of the Redis index.
`client`	`Redis`	Redis async client instance.
`em_invoker`	`BaseEMInvoker`	Embedding model for vectorization.
`index`	`Any`	RedisVL AsyncSearchIndex instance.

Initialize the Redis vector capability.

Schema will be automatically inferred from chunks when creating a new index, or auto-detected from an existing index when performing operations.

Parameters:

Name	Type	Description	Default
`index_name`	`str`	Name of the Redis index.	required
`client`	`Redis`	Redis async client instance.	required
`em_invoker`	`BaseEMInvoker`	Embedding model for vectorization.	required
`encryption`	`EncryptionCapability \| None`	Encryption capability for field-level encryption. Defaults to None.	`None`
`default_batch_size`	`int \| None`	Default batch size for create/update. Defaults to None.	`None`

Ensure Redis vector index exists, creating it if necessary.

This method is idempotent - if the index already exists, it will skip creation and return early.

Parameters:

Name	Type	Description	Default
`filterable_fields`	`list[dict[str, Any]] \| None`	List of filterable field configurations to use when creating a new index. Each field should be a dictionary with "name" and "type" keys. For example: [{"name": "metadata.category", "type": "tag"}, {"name": "metadata.score", "type": "numeric"}] If not provided and index doesn't exist, a default schema will be created with only basic fields (id, content, metadata, vector). Defaults to None.	`None`
`**kwargs`	`Any`	Additional keyword arguments (e.g. from base capability interface); Unused in this implementation.	`{}`

Raises:

Type	Description
`RuntimeError`	If index creation fails.
