https://dev.mysql.com/doc/refman/8.0/en/innodb-memcached-developing.html
Typically, writing an application for the InnoDB memcached plugin involves some degree of rewriting or adapting existing code that uses MySQL or the memcached API. With the daemon_memcached plugin, instead of many traditional memcached servers ...
https://dev.mysql.com/doc/refman/8.0/en/innodb-memcached-intro.html
The InnoDB memcached plugin implements memcached as a MySQL plugin daemon that accesses the InnoDB storage engine directly, bypassing the MySQL SQL layer. The following diagram illustrates how an application accesses data through the ...
https://dev.mysql.com/doc/refman/8.0/en/innodb-memcached-porting-mysql.html
Consider these aspects of memcached applications when adapting an existing MySQL schema or application to use the daemon_memcached plugin: memcached keys cannot contain spaces or newlines, because these characters are used as separators in the ...
https://dev.mysql.com/doc/refman/8.0/en/innodb-memcached-tuning.html
Because using InnoDB in combination with memcached involves writing all data to disk, whether immediately or sometime later, raw performance is expected to be somewhat slower than using memcached by itself. When using the InnoDB memcached plugin, ...
https://dev.mysql.com/doc/refman/8.0/en/innodb-memcached.html
Important The InnoDB memcached plugin was removed in MySQL 8.3.0, and was deprecated in MySQL 8.0.22. The InnoDB memcached plugin (daemon_memcached) provides an integrated memcached daemon that automatically stores and retrieves data from InnoDB ...
https://dev.mysql.com/doc/refman/8.0/en/innodb-online-ddl-performance.html
Online DDL improves several aspects of MySQL operation: Applications that access the table are more responsive because queries and DML operations on the table can proceed while the DDL operation is in progress. Reduced locking and waiting for MySQL ...
https://dev.mysql.com/doc/refman/8.0/en/innodb-online-ddl.html
The online DDL feature provides support for instant and in-place table alterations and concurrent DML. Benefits of this feature include: Improved responsiveness and availability in busy production environments, where making a table unavailable for ...
