Batch

Each HTTP connection that your application makes results in a certain amount of overhead.
This library supports batching, to allow your application to put several API calls into a single HTTP request.
Examples of situations when you might want to use batching:

You have many small requests to make and would like to minimize HTTP request overhead.

A user made changes to data while your application was offline, so your application needs to synchronize its local data with the server by sending a lot of updates and deletes.

Note: You're limited to 1000 calls in a single batch request. Many APIs enforce stricter quotas in addition to that limit.
If you need to make more calls than an API allows, use multiple batch requests.

Details

Create batch requests by calling the batch method and supply a block. All calls made within the block are batched together.

In the following code snippet, two API requests are batched to a single HTTP request, and each API request is supplied a callback:

zoo = Google::Apis::ZooV1::ZooService.new
zoo.batch do |zoo|
zoo.get_animal('elephant') do |animal, err|
# do something with the elephant
end
zoo.list_animals() do |animals, err|
# do something with the list of animals
end
end

Note that when calling methods in batch a block must be supplied to handle the result and potential
error. You can also supply a single callback that gets called for each response:
