filter str

Optional. Lists the Features that match the filter expression. The following filters are supported: - value_type: Supports = and != comparisons. - create_time: Supports =, !=, <, >, >=, and <= comparisons. Values must be in RFC 3339 format. - update_time: Supports =, !=, <, >, >=, and <= comparisons. Values must be in RFC 3339 format. - labels: Supports key-value equality as well as key presence. Examples: - value_type = DOUBLE --> Features whose type is DOUBLE. - create_time > "2020-01-31T15:30:00.000000Z" OR update_time > "2020-01-31T15:30:00.000000Z" --> EntityTypes created or updated after 2020-01-31T15:30:00.000000Z. - labels.active = yes AND labels.env = prod --> Features having both (active: yes) and (env: prod) labels. - labels.env: * --> Any Feature which has a label with 'env' as the key.

order_by str

Optional. A comma-separated list of fields to order by, sorted in ascending order. Use "desc" after a field name for descending. Supported fields: - feature_id - value_type - create_time - update_time

project str

Optional. Project to list features in. If not set, project set in aiplatform.init will be used.

location str

Optional. Location to list features in. If not set, location set in aiplatform.init will be used.

credentials auth_credentials.Credentials

search(
    query: Optional[str] = None,
    page_size: Optional[int] = None,
    project: Optional[str] = None,
    location: Optional[str] = None,
    credentials: Optional[google.auth.credentials.Credentials] = None,
)

Searches existing managed Feature resources.

Example Usage:

my_features = aiplatform.Feature.search()
Parameters
NameDescription
query str

Optional. Query string that is a conjunction of field-restricted queries and/or field-restricted filters. Field-restricted queries and filters can be combined using AND to form a conjunction. A field query is in the form FIELD:QUERY. This implicitly checks if QUERY exists as a substring within Feature's FIELD. The QUERY and the FIELD are converted to a sequence of words (i.e. tokens) for comparison. This is done by: - Removing leading/trailing whitespace and tokenizing the search value. Characters that are not one of alphanumeric [a-zA-Z0-9], underscore _, or asterisk * are treated as delimiters for tokens. * is treated as a wildcard that matches characters within a token. - Ignoring case. - Prepending an asterisk to the first and appending an asterisk to the last token in QUERY. A QUERY must be either a singular token or a phrase. A phrase is one or multiple words enclosed in double quotation marks ("). With phrases, the order of the words is important. Words in the phrase must be matching in order and consecutively. Supported FIELDs for field-restricted queries: - feature_id - description - entity_type_id Examples: - feature_id: foo --> Matches a Feature with ID containing the substring foo (eg. foo, foofeature, barfoo). - feature_id: foo*feature --> Matches a Feature with ID containing the substring foo*feature (eg. foobarfeature). - feature_id: foo AND description: bar --> Matches a Feature with ID containing the substring foo and description containing the substring bar. Besides field queries, the following exact-match filters are supported. The exact-match filters do not support wildcards. Unlike field-restricted queries, exact-match filters are case-sensitive. - feature_id: Supports = comparisons. - description: Supports = comparisons. Multi-token filters should be enclosed in quotes. - entity_type_id: Supports = comparisons. - value_type: Supports = and != comparisons. - labels: Supports key-value equality as well as key presence. - featurestore_id: Supports = comparisons. Examples: - description = "foo bar" --> Any Feature with description exactly equal to foo bar - value_type = DOUBLE --> Features whose type is DOUBLE. - labels.active = yes AND labels.env = prod --> Features having both (active: yes) and (env: prod) labels. - labels.env: * --> Any Feature which has a label with env as the key. This corresponds to the query field on the request instance; if request is provided, this should not be set.

page_size int

Optional. The maximum number of Features to return. The service may return fewer than this value. If unspecified, at most 100 Features will be returned. The maximum value is 100; any value greater than 100 will be coerced to 100.

project str

Optional. Project to list features in. If not set, project set in aiplatform.init will be used.

location str

Optional. Location to list features in. If not set, location set in aiplatform.init will be used.

credentials auth_credentials.Credentials

Optional. Custom credentials to use to list features. Overrides credentials set in aiplatform.init.
