Postgresql is a popular database, and it has been used for a long time in the Golang ecosystem. It is a powerful and versatile data storage system that offers many benefits. For example, it supports multi-threading, improves performance, and enables ssl mode.
Saves 700 LOC of trivial and repetitive code
The database/PostgreSQL in Golang makes it easy to use Postgresql. However, it is not a replacement for SQL. It is merely an abstraction for using SQL. There is no guarantee that it will always perform better.
Supports multi-threading
Multi-threading is a programming concept in which a program divides its code into smaller units to execute in parallel. Multithreading is an excellent way to improve your program’s performance, as it allows multiple processes to share the same resources, including memory. In this way, your program is able to handle more requests and better interact with your users. Using this technique can save you both time and energy.
While multi-threading makes your application faster, it also has its drawbacks. Because threads share memory, they can cause data corruption. In addition, concurrent operations are prone to deadlocking, which results in the failure of a program. You can detect deadlocks using a tool such as FusionReactor.
Improves performance
One way to improve the performance of PostgreSQL in Go is by using the PostgreSQL server’s in-memory database cache, Redis. By using Redis to store database objects, you will avoid unnecessary roundtrips to the server and improve user experience. It can also help you reduce database costs by only caching data that is unlikely to change.
The database/sql library for Go includes some basic support for PostgreSQL, but is not a specialist library. Specialist libraries have nice features and can improve the performance of applications connecting to PostgreSQL. One such library is jackc/pgx, which is similar to database/sql, but uses Go modules to simplify the library and improve performance.
Supports ssl mode
The postgresql package in Golang now supports SSL mode. This option is disabled by default, but you can switch to it by setting sslmode=require in your Go project. The following example shows how to connect to a PostgreSQL server in Go.
Enabling SSL mode can help protect your data. It is also a good way to improve performance. There are two modes available for using SSL: full and verify-ca. Both modes have different benefits and drawbacks. Full mode allows you to connect to servers that are registered with a CA. However, it’s not as secure as verify-ca.
By default, most Postgresql clients do not support SSL, but you can enable it by choosing “allow” or “disable” under advanced configuration options. You can also use the “sslmode” parameter to specify the path for which to try encryption. If SSL fails, most Postgresql servers will fall back to an unencrypted connection, which exposes your data.
Increases concurrency
Postgresql is one of the most widely used database systems and it is a powerful database management system that helps database administrators manage data efficiently. In addition, the Postgres database engine is able to support large numbers of concurrent connections. This makes Postgres an excellent choice for building databases for high-performance applications. However, the Postgres database engine has some drawbacks. Let’s take a look at some of them.
Postgres is a relational database that stores data in tuples, or tables. Its tables store information in a consistent, valid state. The database is very flexible, with the ability to add or remove user-defined functions and dynamically-load code changes. Its flexibility and extensibility are essential in certain industries and lines of business.
