A low-level client representing Amazon Cognito Sync
Amazon Cognito Sync provides an AWS service and client library that enable cross-device syncing of application-related user data. High-level client libraries are available for both iOS and Android. You can use these libraries to persist data locally so that it’s available even if the device is offline. Developer credentials don’t need to be stored on the mobile device to access the service. You can use Amazon Cognito to obtain a normalized user ID and credentials. User data is persisted in a dataset that can store up to 1 MB of key-value pairs, and you can have up to 20 datasets per user identity.
With Amazon Cognito Sync, the data stored for each identity is accessible only to credentials assigned to that identity. In order to use the Cognito Sync service, you need to make API calls using credentials retrieved with Amazon Cognito Identity service .
If you want to use Cognito Sync in an Android or iOS application, you will probably want to make API calls via the AWS Mobile SDK. To learn more, see the Developer Guide for Android and the Developer Guide for iOS .
client = session.create_client('cognito-sync')
These are the available methods:
Initiates a bulk publish of all existing datasets for an Identity Pool to the configured stream. Customers are limited to one successful bulk publish per 24 hours. Bulk publish is an asynchronous request, customers can see the status of the request via the GetBulkPublishDetails operation.
This API can only be called with developer credentials. You cannot call this API with the temporary user credentials provided by Cognito Identity.

as the method name on the client. For example, if the

operation can be paginated, you can use the
call client.get_paginator("create_foo")
.

False
otherwise.
Closes underlying endpoint connections.
Deletes the specific dataset. The dataset will be deleted permanently, and the action can’t be undone. Datasets that this dataset was merged with will no longer report the merge. Any subsequent operation on this dataset will result in a ResourceNotFoundException.

Exceptions
Posts updates to records and adds and deletes records for a dataset and user.
The sync count in the record patch is your last known sync count for that record. The server will reject an UpdateRecords request with a ResourceConflictException if you try to patch a record with a new value but a stale sync count.
For example, if the sync count on the server is 5 for a key called highScore and you try and submit a new highScore with sync count of 4, the request will be rejected. To obtain the current sync count for a record, call ListRecords. On a successful update of the record, the response returns the new sync count for that record. You should present that sync count the next time you try to update that same record. When the record does not exist, specify the sync count as 0.
This API can be called with temporary user credentials provided by Cognito Identity or with developer credentials.
