Properties

Filter

public string Filter { get; set; }

Filter specifying the boolean condition for the Contexts to satisfy in order to be part of the result set. The syntax to define filter query is based on https://google.aip.dev/160. Following are the supported set of filters:

  • Attribute filtering: For example: display_name = "test". Supported fields include: name, display_name, schema_title, create_time, and update_time. Time fields, such as create_time and update_time, require values specified in RFC-3339 format. For example: create_time = "2020-11-19T11:30:00-04:00".
  • Metadata field: To filter on metadata fields use traversal operation as follows: metadata.<field_name>.<type_value>. For example: metadata.field_1.number_value = 10.0. In case the field name contains special characters (such as colon), one can embed it inside double quote. For example: metadata."field:1".number_value = 10.0

  • Parent Child filtering: To filter Contexts based on parent-child relationship use the HAS operator as follows:

    parent_contexts:
"projects/<project_number>/locations/<location>/metadataStores/<metadatastore_name>/contexts/<context_id>"
child_contexts:
"projects/<project_number>/locations/<location>/metadataStores/<metadatastore_name>/contexts/<context_id>"

Each of the above supported filters can be combined together using logical operators (AND & OR). Maximum nested expression depth allowed is 5.

For example: display_name = "test" AND metadata.field1.bool_value = true.

string

OrderBy

public string OrderBy { get; set; }

How the list of messages is ordered. Specify the values to order by and an ordering operation. The default sorting order is ascending. To specify descending order for a field, users append a " desc" suffix; for example: "foo desc, bar". Subfields are specified with a . character, such as foo.bar. see https://google.aip.dev/132#ordering for more details.

Property Value
Type Description
string

PageSize

public int PageSize { get; set; }

The maximum number of Contexts to return. The service may return fewer. Must be in range 1-1000, inclusive. Defaults to 100.

Property Value
Type Description
int

PageToken

public string PageToken { get; set; }

A page token, received from a previous [MetadataService.ListContexts][google.cloud.aiplatform.v1.MetadataService.ListContexts] call. Provide this to retrieve the subsequent page.

When paginating, all other provided parameters must match the call that provided the page token. (Otherwise the request will fail with INVALID_ARGUMENT error.)
