What Is Memcached?

Memcached is a powerful and efficient in-memory data store that substantially boosts application performance through its caching capabilities. By strategically storing frequently accessed data , Memcached vastly reduces the need for repetitive database queries, resulting in remarkably faster read and write operations.

In This Article

Memcached operates as a key-value store, where data is organized and retrieved using unique keys, each corresponding to a specific value. This simplicity and versatility allow Memcached to cater to various caching needs, making it a preferred choice for querying results, authentication mechanisms, performing computations, and fetching URLs.

One of Memcached’s notable features is its distributed architecture, enabling seamless scalability across multiple servers, paving the way for horizontal scaling, and easily accommodating growing demands. Through the strategic use of configurable expiration times, Memcached ensures that cached data remains relevant and up-to-date.

What Are the Pros of Memcached?

  • Fast Access Times

    Memcached stores data in the RAM of servers, which allows for incredibly fast read and write operations. Retrieving data from memory is much quicker than fetching it from disk-based storage or a remote database.

  • Caching Efficiency

    By caching data that is computationally expensive or time-consuming to generate, Memcached significantly reduces the workload on backend databases, application servers, and external APIs.

  • Scalability

    Memcached’s distributed architecture enables seamless scalability across multiple servers, increasing the cache capacity and handling more concurrent users without sacrificing performance.

  • Simplicity and Flexibility

    Memcached operates as a straightforward key-value store, making integrating various applications accessible.

  • Protocol Support and Client Libraries

    Memcached provides a simple text-based protocol supported by a wide range of client libraries in various programming languages, making implementing Memcached in different tech stacks straightforwardly.

  • Reduced Database Load

    By caching frequently requested data in Memcached, the number of queries hitting the backend databases is reduced. This speeds up response times but also helps to alleviate database load.

  • Cost-Effectiveness

    Since Memcached uses server RAM for caching, it can be more cost-effective than expanding storage on high-performance database systems.

  • Real-Time Data Access

    Memcached is designed for low-latency data access. It is ideal for real-time applications, such as gaming, social networking platforms, and financial systems, where immediate access to frequently updated data is crucial.

What Are the Cons of Memcached?

  • Data Volatility

    Memcached is an in-memory caching system, which means that in the event of a server restart or failure, all cached data is lost. This makes it unsuitable for caching critical or sensitive data.

  • No Built-in Data Persistence

    Memcached does not provide built-in mechanisms for data persistence, meaning it does not automatically store data to disk or any permanent storage medium.

  • Memory Overhead

    Memcached consumes server RAM to store cached data as an in-memory caching system. This can increase memory overhead, especially if the cached dataset is extensive.

  • Limited Query Capabilities

    Memcached is designed for simple key-value data storage and retrieval. It lacks more advanced querying capabilities available in databases.

  • Key Limitations

    Memcached limits the size of keys and values stored, depending on the specific implementation and configuration. Long keys or large values can be problematic.

  • Single Point of Failure

    While Memcached is designed to be distributed across multiple servers for high availability, individual Memcached servers can still be single points of failure.

  • Lack of Security Features

    Memcached needs to have built-in security features like authentication and encryption. Exposing Memcached to untrusted networks without proper security measures can lead to potential data breaches.

  • Learning Curve

    While Memcached is relatively simple, mastering its more advanced features, managing cache invalidation, and handling cache consistency can require additional effort and expertise.

Database Alternatives to Memcached?

Redis

Redis is an in-memory data structure store that also supports persistent storage. It offers many data structures, including strings, lists, sets, hashes, and more. 

Apache Kafka

Kafka is a distributed streaming platform that excels in handling real-time data streams. It is primarily used for building real-time data pipelines and streaming applications. 

Amazon ElastiCache

ElastiCache is a fully managed caching service provided by Amazon Web Services (AWS). It supports both Memcached and Redis as caching engines. 

Apache Ignite

Apache Ignite is an open-source, distributed, in-memory computing platform that provides caching, compute grid and data grid capabilities. It can be used for real-time data processing, distributed computing, and caching.

Google Cloud Memorystore

Like Amazon ElastiCache, Google Cloud Memorystore is a fully managed caching service that Google Cloud Platform (GCP) provides. It supports both Memcached and Redis as caching engines and offers automatic scaling, backup, and high availability features.
