NDB Cluster: The NDB Cluster storage engine is the best choice when working with a clustered environment for high redundancy and distributed computing.

EXAMPLE: This storage engine is a template with no built-in functionality that shows developers how to build a new customer storage engine.MERGE: The MERGE engine lets developers combine identical versions of MyISAM tables and treat them as a single entity, which can be useful for reporting.

BLACKHOLE: BLACKHOLE does not store any data it receives.

ARCHIVE: The ARCHIVE engine’s purpose is to write and archive data.

CSV: Because the CSV engine stores data as character- or comma-separated value text files, it's best used when data needs to be shared with other CSV-formatted applications.

MEMORY: The MEMORY engine is used for temporary tables or staging areas that perform noncritical data operations such as caching and transient session management.

MyISAM: MyISAM is a fast storage engine that's optimized for use in read-heavy applications.

MySQL supports eight alternative storage engines: MySQL's default storage engine is InnoDB, which emphasizes ACID compliance and high performance. Storage engine supportĭatabases use storage engines to read, write, and modify data. Accounting for system performance with scale using PostgreSQL will require more capacity planning than with MySQL. This difference in memory pressure becomes increasingly important when using PostgreSQL and MySQL at scale.

MySQL uses a single process and maintains one thread (or path of execution) per connection, which results in less memory pressure. PostgreSQL starts a new process with its own memory allocation for each connection it establishes, so it requires a lot of memory on systems with a high number of client connections. multiprocessĪnother significant difference revolves around the way each database runs on a server: PostgreSQL uses multiple processes, while MySQL runs in a single process. MySQL is a conventional relational database that does not provide as strong of a level of support for new features, extensions, and data source integration as PostgreSQL. PostgreSQL is an object-relational database management system that emphasizes extensibility with easy integration of new data sources and extensions. The main differences between PostgreSQL and MySQL lies within each database's architecture. Let's look at each of these factors in detail.
