Request syntax​

wait_for_index_building_complete(
    collection_name: str,
    index_name: str = "",
    timeout: float | None,
    using: str = "default",
)

PARAMETERS:

  • collection_name (str) -

    [REQUIRED]

    The name of an existing collection.

    Setting this to a non-existing collection leads to a CollectionNotExistException.

  • index_name (str) -

    The name of the target index of this operation.

    If left unspecified, the default index applies. If the collection has multiple indexes, this parameter is mandatory.

    Setting this to a non-existing index leads to an IndexNotExistException.

  • using (str) -

    The alias of the employed connection.

    The default value is default, indicating that this operation employs the default connection.

  • timeout (float | None)

    The timeout duration for this operation. Setting this to None indicates that this operation times out when any response arrives or any error occurs.

RETURN TYPE:

NoneType

RETURNS:

None

EXCEPTIONS:

  • CollectionNotExistException

    This exception will be raised if the specified collection does not exist.

  • IndexNotExistException

    This exception will be raised if the specified index does not exist.

  • AmbiguousIndexName

    This exception will be raised if multiple indexes exist but the index name is left unspecified.
