Methods:

save() -> None Saves the metadata schema to the backend if it has been modified.

​
save

def save() -> None

Saves the metadata schema to the backend if changes have been made.

​
add_embedding

def add_embedding(k: str, *, size: int) -> None

Adds a new embedding to the metadata schema.

Arguments:

k : str The key under which the embedding will be stored in the schema. size : int The size of the embedding.

Raises:

MetadataSchemaError If the key k is already defined in the schema.

​
add_enum

def add_enum(k: str, *, values: Sequence[str]) -> None

Adds a new enum to the metadata schema.

Arguments:

k : str The key under which the embedding will be stored in the schema. values : Sequence[str] The set of values for the enum (min 1, max 256).

Raises:

MetadataSchemaError If the key k is already defined in the schema.

​
add_enum_options

def add_enum_options(k: str, *, values: Sequence[str]) -> None

Adds extra valid enum values to an existing enum schema.

Arguments:

k : str The key referencing the enum. values : Sequence[str] The set of new values to add to the enum (min 1, max 256).

Raises:

MetadataSchemaError If the key k is not defined in the schema or is not an enum.

​
add_scalar

def add_scalar(
    k: str, *, data_type: Literal["boolean", "datetime", "number", "uuid",
                                  "text", "varchar", "string", "long_string"]
) -> None

Sets a simple metadata type for a given key in the schema.

Arguments:

k : str The key for which the metadata type is being set. schema : Literal[ “boolean”, “datetime”, “number”, “uuid”, “text”, “varchar”, “string”, “long_string” ] The type of metadata to be associated with the key. Must be a valid identifier. “string” is an alias of “varchar” “long_string” is an alias of “text”

Raises:

MetadataSchemaError If the key k is already defined in the schema with a conflicting type.

​
delete_key

def delete_key(k: str) -> None

Delete a metadata key from the schema, this cannot be undone.

Arguments:

k : str The key for which the metadata type is being deleted.

Raises:

MetadataSchemaError If the key k is already deleted or not present in the schema

​
keys

def keys() -> Sequence[str]

Returns a sequence of all keys defined in the metadata schema.

Returns:

Sequence[str] A list of keys present in the metadata schema.

​
has_key

def has_key(k: str) -> bool

Check if any definition exists for a key.

Arguments:

k : str The key for which the metadata type is to be retrieved.

​
is_key_deleted

def is_key_deleted(k: str) -> bool

Check if the key is defined as deleted. (Tombstone type)

Arguments:

k : str The key for which the metadata type is to be retrieved.

​
get_key_type

def get_key_type(
    k: str
) -> Union[Literal["boolean", "datetime", "uuid", "number", "varchar", "text",
                   "embedding", "enum"], None]

Retrieves the metadata type associated with a given key.

Arguments:

k : str The key for which the metadata type is to be retrieved.

Returns:

Literal[“boolean”, “datetime”, “uuid”, “number”, “varchar”, “text”, “embedding”, “enum”] The metadata type associated with the key k.

Raises:

MetadataSchemaError If the key k is not supported by the current SDK.

​
get_embedding_size

def get_embedding_size(k: str) -> int

Retrieves size associated with a given embedding.

Arguments:

k : str The key for which the metadata type is to be retrieved.

Returns:

int The size of the embedding

Raises:

MetadataSchemaError If the key k is not defined in the schema or is not an embedding

​
get_enum_options

def get_enum_options(k: str) -> Sequence[str]

Retrieves all values associated with a given enum.

Arguments:

k : str The key for which the metadata type is to be retrieved.

Returns:

Sequence[str] The list of all values associated with an enum type

Raises:

MetadataSchemaError If the key k is not defined in the schema or is not an enum
