![]() ![]() MySQL concurrency adds a level of sophistication. This is typically not an issue, but if you need more advanced concurrency you look into addons like SQLite.swift, FMDB or GRDB. It fully supports multithreaded applications and if 2 threads are attempting to write at the same time, one will have to wait until the other is completed. SQLite only allows a single database write at a time. MySQL fields can be encrypted via the AES_ENCRYPT and AES_DECRYPT functions SQLCipher is a SQLite extension that will encrypt your database with a 256bit AES key. MySQL includes a DB server execution language called MySQLScript.ĭatabase encryption is not supported out of the box, but it is possible to extend SQLite functionality. SQLite is an embedded database so it doesn't make sense for it to have a server side execution language. Tables can be a maximum of 64TB without partitioning and rows can be up to 4GB in size. With partitioning the database size is virtually unlimited. MySQL is licensed by Oracle, but MariaDB which is a forked version of MySQL is open source This table summarizes how SQLite and MySQL compare on DB features. Their limitations are unlikely to ever be exceeded as the system hardware and OS limitations will likely be hit first. SQLite and MySQL are both very capable technologies for the purposes they were created to achieve. The query cache does not scale well with high throughput workloads on multi core machines. The query cache is deprecated as of version 5.7 and removed in version 8. The following diagram shows the major components involved in handling SQL statements. EXAMPLE - serves as an example for storage engine developers.ARCHIVE - Useful for large data, does not support indexes.CSV - Stores table data in comma seperated value files.MyISAM - Non transactional, High speed storage and retrieval.MySQL allows you to swap storage engines which enables specific functionality. Note that SQLite has a query optimizer implemented in the Next Generation Query Planner. Richard Hipp's SQLite presentation from the "Databaseology Lectures" at Carngie Melon University in 2015. The following diagram is a slide taken from Dr. When trying to determine whether to choose MySQL, MariaDB, MySQL embedded or SQLite, consider the following, In this SQLite vs MySQL comparison I dig into 9 different aspects of these technologies. MySQL Workbench is a GUI based management tool with a visual approach to database design. MySQL also provides a fully feature command line to manage databases and execute SQL statements. SQLite Workbench is an Open Source project that provides a visual GUI experience to manage SQLite databases. SQLite provides a simple command line tool to interact with a SQLite database using SQL statements. SQLite supports atomic transactions.įor high transaction loads with thousands of writes per second MySQL is a good choice. ![]() These transactions occur very quickly so it works for small and medium transaction loads. It uses a single write, multi read concurrency model, so only one database write can be in progress at a time. SQLite can support multiple threads and processes and therefore multiple users accessing the database. ![]() MariaDB is a highly compatible Open Source fork of MySQL and can be used at no cost. ![]() SQLite is fully Open Source and can be used at no cost. The database runs in a data center on a server machine and is accessed via the network from the client application. MySQL and it's Open Source offshoot MariaDB use the 'server' architecture similar to traditional databases like Oracle and SQLServer. The entire database is stored in a single file. It is also built using ubiquitous and generic C libraries, making it highly portable across OS platforms. SQLite is very compact and resource efficient. SQLite is one of the most widely used software systems in the world due to its suitability in embedded, mobile and IoT applications. Here's a summary table showing how SQLite and MySQL compare at a high level. SQLite is great for embedded applications like mobile apps, and IoT edge, whereas MySQL is great for client server and multiuser, high transaction systems. SQLite and MySQL are very different technologies designed for different purposes, so comparing them is a bit like comparing oranges and apples. They are used to store data, using a relational model, manipulated by the SQL language. SQLite and MySql are database technologies. ![]()
