WhatsApp is one of the most popular messaging applications used worldwide. It can be used to send and receive messages, photos, videos, audio recordings and other documents.
It has become a part of our daily lives as it helps us stay connected with our friends and family. But what many people don’t know is which database WhatsApp uses to store all this data.
WhatsApp primarily uses SQLite. SQLite is an open source, self-contained, serverless, zero-configuration and transactional SQL database engine.
It is well known for its small footprint and efficient data storage. SQLite is suitable for use in mobile applications as it takes up very little disk space and uses minimal CPU power.
SQLite does not require a server or any configuration like other databases such as MySQL or PostgreSQL do. This makes it ideal for mobile applications as it can be run on the same device without any additional setup. SQLite also supports ACID transactions which provide reliable data consistency when multiple users are accessing the same data simultaneously.
WhatsApp also makes use of Redis. Redis is an open source in-memory data structure store used for caching data in order to improve the performance of applications. Redis stores the most frequently accessed data in memory so that it can be quickly retrieved without having to query the database every time.
In conclusion, WhatsApp uses two different databases – SQLite, an open source, self-contained, serverless, zero-configuration and transactional SQL database engine; and Redis, an open source in-memory data structure store used for caching data – to efficiently store its user’s messages, photos, videos, audio recordings and other documents. Both databases are well suited for mobile applications due to their low resource requirements and fast performance.
