Batch Processing

While most services provide synchronous APIs, requiring you to make a request and then wait for a response, BatchJobService provides a way to perform batches of operations on multiple services without synchronously waiting for the operations to complete.

Unlike service-specific mutate operations, a single job in BatchJobService can operate against a mixed collection of campaigns, ad groups, ads, criteria, labels, and feed items. Submitted jobs run in parallel, and BatchJobService automatically retries operations that fail due to transient errors such as rate limit errors. The Google Ads API still counts each operation towards your daily operation limit following the API operations counting instructions.

In addition, BatchJobService lets you use temporary IDs within your requests so you can submit dependent operations in a single job.

Note: Use of BatchJobService can reduce the number of requests sent but its use must be evaluated to see if it's a good fit for your needs. The main reasons for using batch processing are to minimize the number of API requests and retry operations that fail due to transient errors. This doesn't guarantee improved performance resulting in higher throughput or quicker job completion. You need to experiment with different combinations of batch and non-batch processing to determine the optimal solution for your circumstances.

Operations

BatchJobService supports all of the operations listed in MutateOperation, with a few important exceptions.

Since the Google Ads API executes all operations in a job with partial failure enabled, if a job is cancelled or individual operations fail, operations that succeeded will not be rolled back.

The following operations in MutateOperation must be atomic, and thus, don't support partial failure and are not supported within batch jobs. Avoid adding them to your jobs, set partial_failure to false in your requests, and use the mutate method in GoogleAdsService instead.
