Advice on guava, Memcached, and Redis

Hi guys! I need an in-memory key/value storage with a lifespan for each key What do you recommend me to use? I was thinking about using a ConcurrentHashMap, with a scheduled thread evicting keys when apply. In fact, it is a possibility due because the performance is not important. But, on the other side, I have considered using any library such as Memcached, Ehcache, guava...

Redis can do the same jobs as Memcached, ECache or any other im-memory caching tool and can do them better. - Redis can act as a cache as well. It can store key/value pairs too. In Redis, they can even be up to 512MB. - Redis is better documented than Memcached and ECached. - Supports many data types. (Strings, Hashes, Lists, Sets, Sorted Sets, Geo, Bitmap and HyperLogLog) - Redis provides pub/sub as well. - Redis can be scaled easily horizontally if needed using its own tool Redis Sentinel. - Wide variety of client libraries in almost every language.

Decisions about guava, Memcached, and Redis
Matthew Evans

The obvious volatile memory choices were either Memcached or Redis. We eventually sided with Redis as it natively handled replication, and this replication fell under the PCI responsibility scope of AWS. This added duribility meant that if a redis node were to die, our downtime would be in the seconds, rather than 15 minutes which we would incur using Memcached

The requirement was the classic "cache the results of a SQL query for a period of time."

While the Internet is full of "Redis is fuller featured" posts, the key issue for us was the actual performance. We discovered, in various stress scenario testing, that Memcached outperformed Redis for simple key-value retrieval dramatically (over twice as fast.) That's not to say that Redis is bad - we use that in other places where the requirements are more sophisticated than simple key/value retrieval.

    What is guava?

    The Guava project contains several of Google's core libraries that we rely on in our Java-based projects: collections, caching, primitives support, concurrency libraries, common annotations, string processing, I/O, and so forth.

    What is Memcached?

    Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.

    What is Redis?

    Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.

    What are some alternatives to guava, Memcached, and Redis?
    Java 8
    It is a revolutionary release of the world鈥檚 no 1 development platform. It includes a huge upgrade to the Java programming model and a coordinated evolution of the JVM, Java language, and libraries. Java 8 includes features for productivity, ease of use, improved polyglot programming, security and improved performance.
    RxJava
    A library for composing asynchronous and event-based programs by using observable sequences for the Java VM.
    Quarkus
    It tailors your application for GraalVM and HotSpot. Amazingly fast boot time, incredibly low RSS memory (not just heap size!) offering near instant scale up and high density memory utilization in container orchestration platforms like Kubernetes. We use a technique we call compile time boot.
    Thymeleaf
    It is a modern server-side Java template engine for both web and standalone environments. It is aimed at creating elegant web code while adding powerful features and retaining prototyping abilities.
    Apache FreeMarker
    It is a "template engine"; a generic tool to generate text output (anything from HTML to auto generated source code) based on templates. It's a Java package, a class library for Java programmers.
