What is Memcached?
Memcached is a distributed memory caching system used to enhance the performance and scalability of web applications by reducing the load on databases. It stores frequently accessed data in memory, allowing for faster retrieval compared to traditional storage methods like disk-based databases. Here’s a breakdown of its role in system design:
- In-Memory Storage: Memcached stores data in RAM, which is much faster than accessing data from a disk.
- Distributed Architecture: It can run on multiple servers, distributing the cache across them to balance the load.
- Key-Value Storage: Data is stored as key-value pairs, making retrieval straightforward and efficient.
- Volatile Storage: Data in Memcached is not persistent; it gets lost if the server restarts or if the cache is full and data is evicted.
What is Memcached?
Memcached is a powerful tool used in system design to speed up web applications by storing data in memory. It works as a caching layer, reducing the time needed to access frequently requested information. This helps websites and services handle more traffic efficiently, making them faster and more responsive. Memcached is widely used in tech companies to improve performance and scalability.
