Features of Memcached
Memcached is a powerful, distributed memory caching system with a variety of features that make it suitable for high-performance applications. Here are some key features:
- Distributed Memory Caching: Memcached distributes data across multiple nodes, enabling horizontal scaling and load balancing.
- High Performance: In-memory storage results in very low latency and high throughput for read and write operations.
- Simple Key-Value Store: Memcached uses a simple key-value store model, which makes it easy to integrate and use.
- Scalability: Memcached can scale horizontally by adding more servers, which allows it to handle increased load efficiently.
- Flexible Memory Allocation: Uses a slab allocator to manage memory efficiently, reducing fragmentation and optimizing resource usage.
- Least Recently Used (LRU) Eviction: Implements an LRU eviction policy to ensure that the most frequently accessed data remains in the cache.
- Consistent Hashing: Distributes keys across nodes using consistent hashing, ensuring even distribution and minimal data movement when nodes are added or removed.
- Non-Persistent Storage: Designed to be a volatile cache, meaning it does not persist data to disk, which enhances performance but requires that the application can handle cache misses gracefully.
- Monitoring and Management Tools: Provides built-in statistics and monitoring capabilities, and integrates well with external monitoring tools.
- Security Features: While Memcached itself lacks built-in authentication and encryption, it can be deployed securely within a trusted network and with additional layers of security, such as SASL authentication and TLS encryption.
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.
