For example, if your job\n contains operations to add campaigns, ad groups, and ad group criteria,\n order the operations in your upload so that all of the [campaign\n operations](/google-ads/api/reference/rpc/v21/CampaignOperation) are first, followed by all of\n the [ad group operations](/google-ads/api/reference/rpc/v21/AdGroupOperation), and finally all\n [ad group criterion operations](/google-ads/api/reference/rpc/v21/AdGroupCriterionOperation).\n\n- Within operations of the same type, it can improve performance to group them\n by parent resource. For example, if you have a series of\n `AdGroupCriterionOperation` objects, it can be more efficient to group\n operations by ad group, rather than intermixing operations that affect ad\n group criteria in different ad groups.\n\nAvoid concurrency issues\n------------------------\n\n- When submitting multiple concurrent jobs for the same account, try to reduce\n the likelihood of jobs operating on the same objects at the same time, while\n maintaining large job sizes. Many unfinished jobs, which have the status of\n [`RUNNING`](/google-ads/api/reference/rpc/v21/BatchJobStatusEnum.BatchJobStatus#running),\n try to mutate the same set of objects, which can lead to deadlock-like\n conditions resulting in severe slow-down and even job failures.\n\n- Don't submit multiple operations that mutate the same object in the same\n job, as the result can be unpredictable.\n\nRetrieve results optimally\n--------------------------\n\n- Don't poll the job status too frequently or you risk hitting rate limit\n errors.\n\n- Don't retrieve more than 1,000 results per page. The server could return\n fewer than that due to load or other factors.\n\n- The results order will be the same as the upload order.\n\nAdditional usage guidance\n-------------------------\n\n- You can set an upper bound for how long a batch job is allowed to run before\n being cancelled. When creating a new batch job, set the\n [`metadata.execution_limit_seconds`](/google-ads/api/reference/rpc/v21/BatchJob.BatchJobMetadata#execution_limit_seconds)\n field to your preferred time limit, in seconds. There is no default time\n limit if `metadata.execution_limit_seconds` is not set.\n\n- It is recommended to add no more than 1,000 operations per\n [`AddBatchJobOperationsRequest`](/google-ads/api/reference/rpc/v21/BatchJobService/AddBatchJobOperations)\n and use the\n [`sequence_token`](/google-ads/api/reference/rpc/v21/AddBatchJobOperationsRequest#sequence_token)\n to upload the rest of the operations to the same job. Depending on the\n content of the operations, too many operations in a single\n `AddBatchJobOperationsRequest` could cause a [`REQUEST_TOO_LARGE`](/google-ads/api/reference/rpc/v21/DatabaseErrorEnum.DatabaseError#request_too_large) error. You\n can handle this error by reducing the number of operations and retrying the\n `AddBatchJobOperationsRequest`.\n\nLimitations\n-----------\n\n- Each [`BatchJob`](/google-ads/api/reference/rpc/v21/BatchJob) supports up to one million\n operations.\n\n- Each account can have up to 100 active or pending jobs at the same time.\n\n- Pending jobs older than 7 days are automatically removed.\n\n- Each [`AddBatchJobOperationsRequest`](/google-ads/api/reference/rpc/v21/BatchJobService/AddBatchJobOperations)\n has a maximum size of 10,484,504 bytes. If you exceed this, you will receive\n an `INTERNAL_ERROR`. You can determine the size of the request before\n submitting and take appropriate action if it is too large.\n\n ### Java\n\n\n static final int MAX_REQUEST_BYTES = 10_484_504;\n\n ...
