display_name str

Required. The display name of the Index. The name can be up to 128 characters long and can be consist of any UTF-8 characters.
contents_delta_uri str

Required. Allows inserting, updating or deleting the contents of the Matching Engine Index. The string must be a valid Google Cloud Storage directory path. If this field is set when calling IndexService.UpdateIndex, then no other Index field can be also updated as part of the same call.

description str

Optional. The description of the Index.
labels Dict[str, str]

Optional. The labels with user-defined metadata to organize your Index. Label keys and values can be no longer than 64 characters (Unicode codepoints), can only contain lowercase letters, numeric characters, underscores and dashes. International characters are allowed. See https://goo.gl/xmQnxf for more information on and examples of labels. No more than 64 user labels can be associated with one Index(System labels are excluded)." System reserved label keys are prefixed with "aiplatform.googleapis.com/" and are immutable.
project str

sync bool

Optional. Whether to execute this creation synchronously. If False, this method will be executed in concurrent Future and any downstream object will be immediately returned and synced when the Future has completed.
encryption_spec str

Optional. Customer-managed encryption key spec for data storage. If set, both of the online and offline data storage will be secured by this key.
