TDSQL-C for MySQL supports the multi-engine feature. The TXSQL engine is 100% compatible with native MySQL, allowing you to migrate MySQL databases to TDSQL-C for MySQL without modifying any application code or configuration. The TXSQL engine is the default engine and can be used for both read-write and read-only instances. The LibraDB engine also supports most MySQL syntax and serves users through read-only instances.
The TXSQL engine kernel also provides various MySQL Enterprise features, such as database audit, thread pool, encryption function, backup, and recovery. The TXSQL engine deeply optimizes the InnoDB storage engine and query optimization, enhancing the database's usability and maintainability. While providing all MySQL features, it also offers enterprise-grade features like disaster recovery, restoration, monitoring, performance optimization, read-write separation, and database audit.
The other engine, LibraDB, is a proprietary engine designed for real-time analysis scenarios. The LibraDB engine supports massive parallelism, vectorized execution engine, and columnar storage, providing high-performance complex data analysis and queries. It supports real-time data queries through read-only instances, avoiding the complexity of ETL components and long data latency. As a pluggable engine, LibraDB can be created within TDSQL-C for MySQL 5.7 and 8.0 clusters (clusters with pre-configured resources).
How to Query Database Kernel Version (TXSQL)?
1. In the tab view, go to the Cluster management tab, and choose Database Version.
2. In the list view, go to the Cluster Details page, and choose Configuration Info > Database Version.
How to Query Database Kernel Version (LibraDB)?
1. For the tab view, on the Cluster Management page, find the analysis engine instance under instance information and click Details. You can view the version under Basic Info.
2. For the list view, on the Cluster Management page, select the Instance List tab and then select Read-Only Analysis Engine. Click the target Instance ID in the list to enter the instance details page. You can view the version under Basic Information.
How do I check the database proxy version?
Go to the Database Proxy tab, and then choose Overview > Basic Info > Proxy Version.
