Cloud Storage client
Some of the workloads on Google Cloud Storage client that are expanding the fastest are data-intensive apps like analytics and AI/ML, but maintaining high throughput for these workloads can be difficult. By giving important client libraries the ability to parallelize uploads and downloads, Google Cloud Storage client library transfer manager increases throughput for your workloads.
To increase throughput, the new transfer manager module makes advantage of many workers in threads or processes. Although Cloud Storage command-line interfaces automatically parallelize downloads and uploads when appropriate, until recently, Google Cloud Storage client libraries did not offer fully controlled parallelism.
The Go transfer manager module is currently in preview and is usually accessible for Java, Node.js, and Python. More language support is being developed. We’ll provide some instances in this post of how Google Cloud Storage client library transfer manager features can significantly increase media operations performance over a sequential model.

How the client library does actions in parallel
Rather than looping over each file one at a time, the transfer manager in the Google Cloud Storage client library can perform concurrent actions on numerous files at once. The transfer manager has methods that accept file-blob pairs as well as ones that make it easy to upload or download entire directories at once. For further information, see the documentation found in the “Getting Started” section below.
The transfer manager offers a “divide-and-conquer” method for tasks involving huge files, which fragments the data in a file and transfers all the shards at once. Ranged reads are used to implement sharding downloads. Upload operations use either the XML multipart upload a API or the gRPC compose API, depending on which client library you choose.
Performance advantages Cloud Storage client
Transfer manager’s performance consequences are contingent upon various operating environments and workloads, which can be accommodated by configuring parallelism accordingly. Depending on the programming language, parallelism may use co-routines, threads, or processes.
When a large amount of data needs to be moved at once, switching from regular transfers to transfers handled by the transfer manager will have the biggest effect on your application. Your application will profit more the more there is to transfer, either in terms of quantity of objects, size of objects, or both.
For instance, on a c3-highcpu-8 Compute Engine instance, the Python library transfer manager module produced a 50x throughput boost over a single-worker solution when downloading a large number of files in less than 16Kbs employing 64 workers! Experiments revealed that very little files benefit most from having a big number of workers. Even though this example uses a disproportionately large number of workers for a small instance, using fewer workers still results in a notable increase in performance.
In the same case, the Google Cloud Storage client library transfer manager enhanced the throughput by 4.5x from a significantly higher beginning baseline when moving larger files of 64MB utilising only 8 workers. Similar performance was seen for sharded uploads and downloads with chunk sizes between 32 and 64 MB.
The best configuration for increasing throughput on a particular application depends on several parameters, such as memory, CPU type, and networking latency. Compute Engine instances, for instance, differ in terms of CPU and memory capacity as well as networking configurations. Similarly, using Cloud Storage from a location other than Compute Engine has very different limits on round-trip time and network throughput.
Client libraries explained
Using client libraries to access Google Cloud APIs from a supported language is simpler. Although you can utilise Google Cloud APIs directly by sending the server raw requests, client libraries simplify the process and cut down on the amount of code you have to write.
The various client libraries for Cloud APIs that Google offers are described in this paper. The documentation for your preferred product or language can also tell you more about the libraries that are available for it.
Libraries for Cloud Clients
When it comes to programmatically accessing Cloud APIs, Cloud Client Libraries are the suggested choice. Utilising the most recent client library concept, cloud client libraries also
- To make Cloud APIs easy to use, provide idiomatic code in each language.
- To make interacting with various Cloud services easier, provide all client libraries a uniform look and feel.
- Take care of every little aspect involved in communicating with the server, such as establishing a Google account.
- Is installable with well-known package management programmes like npm and pip.
- Give you performance advantages in some situations by utilising gRPC. Refer to the gRPC APIs for additional details.
On the Client Libraries page for the Cloud APIs you’re using, you can discover installation guidelines and documentation for the Cloud Client Library. On the Cloud Client Libraries page, you will discover links to the reference material and an introduction to the Cloud Client Libraries.
Client Libraries for Google APIs
Not all languages have Cloud Client Libraries available for all Google Cloud APIs. You can still use the older type of client library, known as Google API Client Libraries, if you want to utilise one of these APIs and there isn’t a Cloud Client Library available for your favourite language. If you’re updating a project that already makes use of these libraries, you might also utilise them. These repositories:
- Grant access to the REST interface of the API alone; gRPC is not accommodated.
- Contain interface code written automatically, which may not be as intuitive as that of the Cloud Client Libraries.
- Take care of every little aspect involved in communicating with the server, such as establishing a Google account.
- Is installable with well-known package management programmes like npm and pip.
- The Client Libraries page for the applicable Cloud APIs has links to these libraries.
Making use of the Firebase mobile app
The Google-wide method for creating mobile applications is called Firebase. It provides an SDK with client code that enables you to use iOS, Android, and Web apps to access Cloud APIs relevant to mobile devices. See the Firebase documentation for details on the available Cloud APIs and how to get started.
