Golang is a relatively young but popular language and is used by companies like IBM and Google. In this article, we discover what makes Golang so special.
1. Prometheus
Prometheus is a very popular open source monitoring tool for recording time series metrics. It works on PromQL and monitors real-time metrics in different formats.
2. Badoo
Badoo is a popular dating app that uses bitmap indexes to search and validate profiles. Since bitmap indexes are difficult to implement in regular databases, it uses Golang for middleware application design. Bitmap indexes are mapped into a mapping tool called Pilosa, which uses a Boolean array to create and optimize queries.
3. SendGrid
SendGrid is a cloud email service that uses Golang to analyze and process millions of messages daily. Golang also handles other engineering aspects such as message acknowledgments, message passing, and scheduling.
Is there any way for a developer to optimize Golang performance?
Although Golang was built for optimization and scaling, there are some things you can do to further optimize your Golang application.
Managing Goroutines
Goroutines are an inexpensive way to handle concurrency in Golang applications. However, they can consume a significant amount of memory if not managed properly. Poor routine management can also lead to performance degradation.
Therefore, you must manage the number of Goroutines in your application architecture. You can use different cores to manage goroutines or use a single thread.
Parallel processing
You can optimize system performance by making I/O operation asynchronous. This can be done by utilizing multiple cores for I/O operations and using variables like sync.WaitGroup for synchronization.
You can also reduce timeout and latency issues for your I/O operations by configuring timing parameters for your tasks and network requests. Avoid locking heavy objects with read and write locks. If locks are unavoidable, use a read-only lock.
Variable Creation
Whenever new variables are created, they take up memory and CPU cycles. A large number of unused variables can cause system latency and make garbage collection difficult for the CPU.
To avoid these problems, you can use predefined variables for your code. You can also use a sync pool for your variable declaration. A synchronization pool is a built-in object pooling tool that caches temporary objects to avoid memory consumption.
Map Optimization
If you are using maps, it is advisable to use integers instead of strings for map keys. This is because integer keys are easier to search for and work with. You can also use binary format for your PostgreSQL scripts.
When should you use Golang?
Golang is a very versatile and promising programming language. Many companies use it to optimize the performance of their products and improve their efficiency. Furthermore, due to its goroutines that handle concurrency issues, it is the perfect language to avoid scalability bottlenecks.
Golang allows developers to create high-performance, lightweight applications that are optimized for performance. Golang applications are easy to maintain and vastly outperform Node.js/Java based applications in terms of performance. For microservices and performance-focused enterprise cloud projects, Golang is a great option.
