describe_dataset

describe_dataset(**kwargs)

Gets meta data about a dataset by identity and dataset name. With Amazon Cognito Sync, each identity has access only to its own data. Thus, the credentials used to make this API call need to have access to the identity data.

This API can be called with temporary user credentials provided by Cognito Identity or with developer credentials. You should use Cognito Identity credentials to make this API call.

response = client.describe_dataset(
    IdentityPoolId='string',
    IdentityId='string',
    DatasetName='string'
)

Parameters

• IdentityPoolId (string) -- [REQUIRED] A name-spaced GUID (for example, us-east-1:23EC4050-6AEA-7089-A2DD-08002EXAMPLE) created by Amazon Cognito. GUID generation is unique within a region.
• IdentityId (string) -- [REQUIRED] A name-spaced GUID (for example, us-east-1:23EC4050-6AEA-7089-A2DD-08002EXAMPLE) created by Amazon Cognito. GUID generation is unique within a region.

Response Structure

• (dict) -- Response to a successful DescribeDataset request.
  • Dataset (dict) -- Meta data for a collection of data for an identity. An identity can have multiple datasets. A dataset can be general or associated with a particular entity in an application (like a saved game). Datasets are automatically created if they don't exist. Data is synced by dataset, and a dataset can hold up to 1MB of key-value pairs.
    • IdentityId (string) -- A name-spaced GUID (for example, us-east-1:23EC4050-6AEA-7089-A2DD-08002EXAMPLE) created by Amazon Cognito. GUID generation is unique within a region.
    • DatasetName (string) -- A string of up to 128 characters. Allowed characters are a-z, A-Z, 0-9, '_' (underscore), '-' (dash), and '.' (dot).
    • CreationDate (datetime) -- Date on which the dataset was created.
    • LastModifiedDate (datetime) -- Date when the dataset was last modified.
    • LastModifiedBy (string) -- The device that made the last change to this dataset.
    • DataStorage (integer) -- Total size in bytes of the records in this dataset.
    • NumRecords (integer) -- Number of records in this dataset.
