MyCAT is an Open-Source software, “a large database cluster” oriented to enterprises. MyCAT is an enforced database which is a replacement for MySQL and supports transaction and ACID. Regarded as MySQL cluster of enterprise database, MyCAT can take the place of expensive Oracle cluster. MyCAT is also a new type of database, which seems like a SQL Server integrated with the memory cache technology, NoSQL technology and HDFS big data. And as a new modern enterprise database product, MyCAT is combined with the traditional database and new distributed data warehouse. In a word, MyCAT is a fresh new middleware of database.

Mycat’s target is to smoothly migrate the current stand-alone database and applications to cloud side with low cost and to solve the bottleneck problem caused by the rapid growth of data storage and business scale.

• Getting Started
• 尝试 MyCAT

• Supports SQL 92 standard
• Supports MySQL cluster, used as a Proxy
• Supports JDBC connection with ORACLE, DB2, SQL Server, simulated as normal MySQL Server connection
• Supports MySQL cluster, percona cluster or mariadb cluster, providing high availability of data fragmentation clusters
• Supports automatic failover and high availability
• Supports separation of read and write, dual-master with multi-slave, single-master with multi-master of MySQL model
• Supports global table, automatically fragment data into multiple nodes for efficient relational query
• Supports the unique fragmentation strategy based on ER-relation for efficient relational query
• Supports multiple platforms, easy deployment and implementation

• Based on Alibaba's open-source project Cobar, whose stability, reliability, excellent architecture and performance, as well as many mature use-cases make MyCAT have a good starting. Standing on the shoulders of giants, MyCAT feels confident enough to go farther.
• Extensively drawing on the best open-source projects and innovative ideas, which are integrated into the Mycat’s gene, make MyCAT be ahead of the other current similar open-source projects, even beyond some commercial products.
• MyCAT behind a strong technical team whose participants are experienced more than five years including some senior software engineer, architect, DBA, etc. Excellent technical team to ensure the product quality of Mycat.
• MyCAT does not rely on any commercial company. It’s unlike some open-source projects whose important features is enclosed in its commercial products and making open-source projects like a decoration.

• On the basis of MySQL’s support, MyCAT add more support of commercial open-source database, including native support of PostgreSQL, FireBird and other open-source databases, as well as indirect support via JDBC of other non-open-source databases such as Oracle, DB2, SQL Server etc.
• More intelligent self-regulating properties, such as automatic statistical analysis of SQL, automatic creating and adjusting indexes. Based on the frequency of read and write, MyCAT automatically optimizes caching and backup strategies
• Achieve a more comprehensive monitoring and management
• Integrated with HDFS, provide SQL commands, load databases into HDFS for rapid analysis
• Integrated excellent open-source reporting tools to make MyCAT have data analysis capability
