The database team at Tencent Cloud supports three distinct kernel branches for MySQL series products: the TXSQL kernel, the TXRocks kernel, and the LibraDB kernel.
TXSQL is a MySQL kernel branch maintained by the Tencent Cloud database team, fully compatible with the native MySQL version. It offers many features similar to those in the MySQL Enterprise Edition, including enterprise-level transparent data encryption, auditing, dynamic thread pooling, encryption functions, backup and recovery, and parallel queries.
TXSQL not only enhances the InnoDB engine, query performance, replication capabilities, and more but also improves the usability and maintainability of TencentDB for MySQL. In addition to offering all MySQL features, it provides enterprise-level advanced features such as disaster recovery, restoration, monitoring, performance optimization, read-write separation, transparent data encryption, and auditing.
TXRocks is a transactional storage engine developed by Tencent's TXSQL team, built upon the RocksDB engine. By leveraging the LSM tree storage structure of RocksDB, TXRocks minimizes wastage caused by partially filled InnoDB pages and fragmentation, while also supporting a compact data format. Consequently, TXRocks can achieve storage efficiency, using only half or even less space compared to InnoDB, without compromising on performance. It is particularly well-suited for applications that demand high transaction read/write performance and manage large volumes of data.
LibraDB is an analytical database engine developed independently by Tencent. It is compatible with the MySQL protocol in a columnar storage environment and supports features such as a highly scalable parallel and vectorized execution engine. Primarily designed to overcome the performance challenges associated with complex SQL queries, LibraDB also features integrated HTAP capabilities, making it suited for real-time reporting, complex analysis, and big data processing scenarios.
