Overview of Memcached

While talking about handling Big Data with MySQL, we would have to obviously think about the performance--how do we handle the performance when storing and retrieving data frequently? One of the prominent answers is Memcached, which boosts the performance of frequent data retrieval and storage because it skips the query parser, SQL optimizer, and other parts of the engine that are unnecessary and allows us to store or retrieve data directly with InnoDB. Using Memcached, data management is much faster and convenient for handling Big Data.

MySQL 8 provides you with the InnoDB Memcached plugin named daemon_memcached, which can help us in managing data easily. It will automatically store and retrieve data from InnoDB tables and provide get, set, and incr operations that remove performance overhead by skipping SQL parsing, which speeds up data operations.

The following diagram will help you understand better how queries are parsed when using Memcache:
