Problems solved by technology

[0002] In Internet database solutions, read-write separation technology is generally used to implement data read and write operations, while traditional read-write separation provides a read-write separation connection string, and non-transactional read requests are based on the read weight ratio configured by the user. Send the read request to the read-only database, but the read request in the transaction will be sent directly to the main instance (that is, the main library, which provides complete services, including the read-write link). If the transaction contains (OLAP, On -LineAnalyticalProcessing) online analytical processing type read requests will cause OLAP read requests to occupy too many resources of the master instance, thus affecting the performance and stability of the master instance

Abstract

The embodiments of this specification provide a data processing method and device, wherein the method includes receiving a data processing request carrying a query statement; converting the query statement into a corresponding relational algebra tree based on the data processing request, and based on the The relational algebra tree determines the operation type corresponding to the query statement; when the operation type is the first type, the query statement is sent to the first database, and the query statement is completed in the first database based on the query statement The data processing request.

Description

technical field [0001] The embodiments of this specification relate to the technical field of data processing, and in particular, to a data processing method. One or more embodiments of this specification also relate to a data processing apparatus, a computing device, and a computer-readable storage medium. Background technique [0002] In Internet database solutions, read-write separation technology is generally used to implement data read and write operations, while traditional read-write separation provides a read-write separation connection string, and non-transactional read requests are based on the read weight ratio configured by the user. Send the read request to the read-only database, but the read request in the transaction will be sent directly to the main instance (that is, the main library, which provides complete services, including the read-write link).
