Memcached is frequently used to increase the speed of dynamic applications that connect to databases. For instance, an in-memory datastore ensures access to the hard disk and doesn’t need to obtain data from memory. It lessens the strain on back-end systems and considerably lowers latency.
Brad Fitzpatrick of Danga Interactive first created Memcached for LiveJournal. Anatoly Vorobey rewrote it from scratch in C after it was initially created in Perl.
These days, Memcached is widely utilized on various platforms, notably YouTube, Twitter, Facebook, and Wikipedia. Additionally, it is made available in various cloud platform services, such as Google App Engine, Microsoft Azure, and Amazon Web Services.
Memcached's in-memory data storage is one of its key characteristics. It implies it can access data considerably more quickly than conventional databases since it keeps data in RAM rather than on disk.
The distributed architecture of Memcached is another noteworthy aspect. It enables various servers to operate as one cohesive unit.
Data stored by Memcached can have its expiration dates specified. You can decide how long the data should stay in the cache before being automatically deleted.
Numerous programming languages, such as PHP, Python, Ruby, Java, and C#, are supported by Memcached.
Memcached is made to manage applications and websites with lots of traffic. Additionally, it can grow horizontally by including more servers in the architecture.
Unlike other caching technologies, Memcached is easy to use and lightweight. It has a minimal memory footprint and doesn't need elaborate installs or setups.
Memcached provides a straightforward API for storing and accessing data from the cache.
Memcached is an established open-source project that is backed by a thriving community. Memcached may be used to boost performance in programs like WordPress and Django.
One well-known NoSQL database is Memcached. This distributed database is free and can speed up database-driven websites.
By storing data and objects in RAM to minimize the number of times an external data source (such as a database or API) must be accessed, Memcached is frequently used to speed up dynamic database-driven websites.
