Abstract

The invention discloses a transaction processing method and device of a distributed database system. The method comprises the following steps: receiving a transaction SQL (Structured Query Language) statement handed by a user via a global transaction processing central server, and generating a SQL syntax tree according to the SQL statement; traversing the SQL syntax tree, and generating a SQL execution tree which can be executed in each database node of the distributed database system according to the distribution situation of the distributed database system; applying for a GTID (Global Transaction ID) corresponding to the SQL execution tree, traversing the SQL execution tree, and issuing the SQL statement on the execution node of the SQL execution tree to be executed on the corresponding database node, wherein the GTID is carried in the SQL statement; and receiving an execution result, traversing the SQL execution tree according to the execution result, returning the execution result to a user after a determination result shows that all SQL statements on the SQL execution tree finish being executed, and releasing the GTID.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a transaction processing method and device of a distributed database system. Background technique [0002] Online transaction processing system (Online Transaction Processing, referred to as OLTP) is a very transactional system, generally a highly available online system. Such a system often handles more than hundreds or thousands of transactions per second, while the execution volume of query statements (select) is thousands or even tens of thousands per second. Typical OLTP systems include e-commerce systems, banking systems, and securities systems. For example, the DB2 business data database used by domestic banks is a typical OLTP database. As the business becomes bigger and bigger, the amount of data will increase, and the calculation will become more and more complex, and the demand for performance, reliability, and scalability will become stronger and stronger. At this ...
