What to Use Instead Of Memcache?

7 minutes read

There are several alternatives to using memcache for caching in your applications. One popular option is Redis, which is an in-memory data structure store that can be used as a database, cache, and message broker. Redis is known for its speed and flexibility, making it a great choice for caching.

Another option is Varnish, a web application accelerator that can also be used as a caching server. Varnish is specifically designed to handle high traffic websites and can greatly improve the performance of your application.

Other alternatives to memcache include Amazon ElastiCache, which is a fully managed in-memory caching service, and Apache Ignite, which is an in-memory computing platform that can be used for caching and processing large data sets.

Ultimately, the best alternative to memcache will depend on your specific application requirements and performance needs. It may be worth experimenting with a few different options to see which one works best for your particular use case.

What are the alternatives to memcache?

Some alternatives to memcache include:

  1. Redis: An open-source, in-memory data structure store that can be used as a database, cache, and message broker. It is known for its speed and support for various data structures.
  2. Cassandra: A distributed NoSQL database that is designed for high availability and scalability. It can be used for caching and storing large amounts of data.
  3. MongoDB: A document-oriented database that is designed for scalability and flexibility. It can be used as a cache and also for storing and querying data.
  4. Couchbase: A NoSQL database that is designed for high performance and scalability. It can be used as a cache and also support various data models.
  5. Memcached: A distributed memory caching system similar to memcache, but with additional features such as support for multi-threaded applications and data persistence.

What are the pros and cons of different alternatives to memcache?

  1. Redis:


  • Redis is a versatile and highly performant in-memory data store.
  • It offers more advanced data structures and operations compared to Memcache, making it suitable for a wider range of use cases.
  • Redis supports persistence and data replication, providing better data durability and high availability.
  • It has a built-in clustering solution, making it ideal for horizontally scaling applications.


  • Redis can be more complex to set up and configure compared to Memcache.
  • It may require more resources to operate effectively, especially when using advanced features or clustering.
  • Redis may have higher latency compared to Memcache for certain use cases.
  1. Apache Kafka:


  • Apache Kafka is a distributed streaming platform that can be used for high-performance caching and messaging.
  • It offers high throughput and fault tolerance, making it suitable for handling large volumes of data.
  • Kafka supports data replication and partitioning, ensuring data durability and scalability.
  • It has robust support for stream processing and real-time analytics.


  • Apache Kafka is more complex to set up and manage compared to Memcache.
  • It may not be as well-suited for simple key-value caching use cases.
  • Kafka may have higher latency compared to Memcache for certain applications.
  1. Amazon ElastiCache (Redis or Memcached):


  • Amazon ElastiCache is a managed caching service, making it easy to deploy and scale.
  • It provides high availability and durability through automated backups and replication.
  • ElastiCache is integrated with other AWS services, enabling seamless integration with existing cloud infrastructures.
  • It offers both Redis and Memcached as caching options, allowing users to choose the best fit for their use case.


  • Amazon ElastiCache may have higher costs compared to self-managed caching solutions.
  • Users may have limited control over the underlying infrastructure and configuration settings.
  • ElastiCache may have some limitations in terms of scalability and customization compared to standalone Redis or Memcached instances.

Overall, the best alternative to Memcached will depend on the specific use case, requirements, and resources available to manage the caching solution. Each alternative has its own strengths and weaknesses, so it's important to carefully evaluate them based on the specific needs of the application.

What are the differences in implementation between memcache and its alternatives?

There are several key differences in implementation between Memcache and its alternatives, such as Redis or Memcached:

  1. Data structure support: Memcache primarily supports key-value pairs, while Redis is more versatile and supports a wider range of data structures, including lists, sets, and hashes. This can make Redis a more attractive option for applications that require more complex data structures.
  2. Persistence: Memcache is an in-memory caching system that does not persist data to disk, meaning that data is lost if the server is restarted or fails. Redis, on the other hand, offers options for persistence, allowing data to be saved to disk and reloaded upon restart.
  3. Scalability: Memcache is designed to be clustered for scalability, but does not natively support sharding or partitioning of data. Redis, on the other hand, supports sharding out of the box, making it easier to scale out horizontally as the data grows.
  4. Replication: Memcache does not have built-in support for replication, while Redis offers options for replication to ensure data availability and fault-tolerance.
  5. Transactions and atomic operations: Redis supports transactions and atomic operations, allowing multiple commands to be executed as a single unit of work. Memcache does not offer the same level of transaction support.
  6. Data eviction policies: Memcache supports eviction policies to manage memory usage by evicting less frequently used data when memory is full. Redis offers more flexible eviction policies and allows for additional configuration options.

Overall, the choice between Memcache and its alternatives will depend on the specific requirements of the application, such as data structure support, persistence, scalability, and transaction support.
