Comparison Of MySQL Database Engines ...
This is a comparison between notable database engines for the MySQL database management system (DBMS). A database engine (or "storage engine") is the underlying software component that a DBMS uses to create, read, update and delete (CRUD) data from a database.

MySQL
MySQL () is an open-source relational database management system (RDBMS). Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, and "SQL", the acronym for Structured Query Language. A relational database organizes data into one or more data tables in which data may be related to each other; these relations help structure the data. SQL is a language programmers use to create, modify and extract data from the relational database, as well as control user access to the database. In addition to relational databases and SQL, an RDBMS like MySQL works with an operating system to implement a relational database in a computer's storage system, manages users, allows for network access and facilitates testing database integrity and creation of backups. MySQL is free and open-source software under the terms of the GNU General Public License, and is also available under a variety of proprietary licenses. MySQL was owned and sponsored by the Swedish com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XtraDB
Percona XtraDB is a storage engine for the MariaDB and Percona Server databases, and is intended as a drop-in replacement to InnoDB, which is the default engine in MySQL MySQL () is an open-source relational database management system (RDBMS). Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, and "SQL", the acronym for Structured Query Language. A relational database .... Up until version 10.1, MariaDB used Percona XtraDB in place of InnoDB as the default storage engine. As of MariaDB 10.2, InnoDB is the default again. XtraDB incorporates InnoDB's ACID-compliant design and MVCC architecture, and allows for a greater degree of tuning and scalability. The engine is also better suited to multi-core processing, which addresses some of the issues known to InnoDB. References External links * {{MySQL Database engines MySQL MariaDB ...

TokuDB
TokuDB is an open-source software, open-source, high-performance storage engine for MySQL and MariaDB. It achieves this by using a fractal tree index. It is Scalability#Database scalability, scalable, ACID and Multiversion concurrency control, MVCC compliant, provides Database index, indexing-based query improvements, offers online Database schema, schema modifications, and reduces Replication (computing)#Database replication, replication lag for both hard disk drives and flash memory. TokuDB is included in Percona Server, MariaDB and Nagios based opmon. However, it is deprecated in Percona Server 8 and MariaDB 10.5. Fractal tree indexes Overview TokuDB uses a Fractal tree index tree data structure that keeps data sorted and allows searches and sequential access in the same time as a B-tree but with insertions and deletions that are asymptotically faster than a B-tree. Fractal trees also allow for messages to be injected into the tree in such a fashion that schema changes (such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPIDER (storage Engine)
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate th ...

Sphinx (search Engine)
Sphinx is a fulltext search engine that provides text search functionality to client applications. Overview Sphinx can be used either as a stand-alone server or as a storage engine ("SphinxSE") for the MySQL family of databases. When run as a standalone server Sphinx operates similar to a DBMS and can communicate with MySQL, MariaDB and PostgreSQL through their native protocols or with any ODBC-compliant DBMS via ODBC. MariaDB, a fork of MySQL, is distributed with SphinxSE. SphinxAPI If Sphinx is run as a stand-alone server, it is possible to use SphinxAPI to connect an application to it. Official implementations of the API are available for PHP, Java, Perl, Ruby and Python languages. Unofficial implementations for other languages, as well as various third party plugins and modules are also available. Other data sources can be indexed via pipe in a custom XML format. SphinxQL The Sphinx search daemon supports the MySQL binary network protocol and can be accessed with the regu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MySQL Cluster
MySQL Cluster is a technology providing shared-nothing clustering and auto-sharding for the MySQL database management system. It is designed to provide high availability and high throughput with low latency, while allowing for near linear scalability. MySQL Cluster is implemented through the NDB or NDBCLUSTER storage engine for MySQL ("NDB" stands for Network Database). Architecture MySQL Cluster is designed around a distributed, multi-master ACID compliant architecture with no single point of failure. MySQL Cluster uses automatic sharding (partitioning) to scale out read and write operations on commodity hardware and can be accessed via SQL and Non-SQL (NoSQL) APIs Replication Internally MySQL Cluster uses synchronous replication through a two-phase commit mechanism in order to guarantee that data is written to multiple nodes upon committing the data. (This is in contrast to what is usually referred to as "MySQL Replication", which is .) Two copies (known as ''replicas'') o ...

MyRocks
MyRocks is open-source software developed at Facebook in order to use MySQL features with RocksDB implementations. It is based on Oracle MySQL 5.6. Starting from version 10.2.5, MariaDB includes MyRocks as an alpha-stage storage engine. MariaDB 10.3.7 includes MyRocks as a storage engine. MyRocks is also shipped with Percona Server. The library is maintained by the Facebook Database Engineering Team. Features RocksDB is optimized for fast, low-latency storage, and MyRocks is aimed at keeping the storage savings efficient. MyRock's efficiency focuses on better space efficiency, better write efficiency, and better read efficiency. * Better space efficiency means using less SSD storage. * Better write efficiency means SSD endurance. * Better read efficiency comes from more available IO capacity for handling queries. Benchmarks Benchmark tests against 3 different instances – MyRocks (compressed), InnoDB (uncompressed), and InnoDB (compressed, 8 KB page size) – found: * My ...

MyISAM
MyISAM was the default storage engine for the MySQL relational database management system versions prior to 5.5 released in December 2009. It is based on the older ISAM code, but it has many useful extensions. Filesystem Each MyISAM table is stored on disk in three files (if it is not partitioned). The files have names that begin with the table name and have an extension to indicate the file type. MySQL uses a .frm file to store the definition of the table, but this file is not a part of the MyISAM engine; instead it is a part of the server. The data file has a .MYD (MYData) extension. The index file has a .MYI (MYIndex) extension. The index file, if lost, can always be recreated by recreating indexes. Files format depends on the ROW_FORMAT table option. The following formats are available: * FIXED: Fixed is a format where all data (including variable-length types) have a fixed length. This format is faster to read, and improves corrupted tables repair. If a table contains big ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
