Required: Yes

createdTime

The date and time that the feature is created.

Type: Timestamp

Required: Yes

evaluationStrategy

If this value is ALL_RULES, the traffic allocation specified by any ongoing launches or experiments is being used. If this is DEFAULT_VARIATION, the default variation is being served to all users.

Type: String

Valid Values: ALL_RULES | DEFAULT_VARIATION

Required: Yes

lastUpdatedTime

The date and time that the feature was most recently updated.

Type: Timestamp

Required: Yes

name

The name of the feature.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 127.

Pattern: ^[-a-zA-Z0-9._]*$

Required: Yes

status

The current state of the feature.

Type: String

Valid Values: AVAILABLE | UPDATING

Required: Yes

valueType

Defines the type of value used to define the different feature variations. For more information, see Variation types

Type: String

Valid Values: STRING | LONG | DOUBLE | BOOLEAN

Required: Yes

variations

An array of structures that contain the configuration of the feature's different variations.

Type: Array of Variation objects

Required: Yes

defaultVariation

The name of the variation that is used as the default variation. The default variation is served to users who are not allocated to any ongoing launches or experiments of this feature.

This variation must also be listed in the variations structure.

If you omit defaultVariation, the first variation listed in the variations structure is used as the default variation.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 127.

Pattern: ^[-a-zA-Z0-9._]*$

Required: No

description

The description of the feature.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 160.

Pattern: .*

Required: No

entityOverrides

A set of key-value pairs that specify users who should always be served a specific variation of a feature. Each key specifies a user using their user ID, account ID, or some other identifier. The value specifies the name of the variation that the user is to be served.

For the override to be successful, the value of the key must match the entityId used in the EvaluateFeature operation.

Key Pattern: .*

Value Length Constraints: Minimum length of 1. Maximum length of 127.

Value Pattern: ^[-a-zA-Z0-9._]*$

Required: No

evaluationRules

An array of structures that define the evaluation rules for the feature.

Type: Array of EvaluationRule objects

Required: No

project

The name or ARN of the project that contains the feature.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 2048.
