Problems solved by technology

[0006] The existing technology only supports the unified synchronization of data and structure with the main database, does not support modifying the original table structure, and at the same time performs data chain stretching operations on the basis of the original synchronization, so it does not meet the above requirements

Embodiment Construction

[0034] The following combination conforms to the present invention to be further described.

[0035] In the binlog analysis method of the present embodiment, SDB and ODB are deployed on the same machine, the database structure is initialized, the file configuration filters out the mysql system library, and the desensitized data field (including user name, phone number, address, user ID, User ID number, etc.), null values ​​and empty string fields are processed separately (NULL-N, EMPTY-E, OTHERS-O), data type conversion when data desensitization, and user identification is modified from long type to varchar type due to encryption. Remove the non-null constraint and index constraint, remove the primary key constraint, and migrate the primary key to ods_id. Do the same when automatically synchronizing data structures. Specify the binlog starting point. In order to speed up the query, the index correlation is automatically added on the basis of the changed table structure.

Abstract

The invention provides a binlog analysis method. The method includes following steps: step 1, creating SDB and ODB to realize alternation and separation of structure and data; step 2, reading and executing configuration for a synchronous program; step 3, running the program, synchronizing data, and altering data; step 4, exiting the program, and recording a binlog file and binlog recording points. Aiming at ODS needs, automatic coupling of data structure with ODS structure, data chain stretching is realized during data synchronizing, and ODS basic data are constructed.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a binlog analysis method. Background technique [0002] The basic data requirements of the business analysis department for ODS (Operational Data Store): [0003] 1. Need to record data change history in real time [0004] 2. The data structure is coupled into the ODS data structure [0005] 3. Data synchronization requires chain stretching [0006] The existing technology only supports the unified synchronization of data and structure with the main database, and does not support the modification of the original table structure, and at the same time perform data chain stretching operations on the basis of the original synchronization, so it does not meet the above requirements. Contents of the invention [0007] The purpose of the present invention is to realize the automatic coupling of the data structure to the ODS structure change, the data chain stretching during the...
