Abstract
A data modification request for modifying data in a primary database is received at the primary database. Based on the data modification request, second data in the primary database is modified to first data. Based on the data modification request, a first log and a second log are generated, where the first log is a simplified log including the first data and the second log is a complete log including the second data. Persistence processing is performed on the first log. A modification result that corresponds to the data modification request is returned.
Claims20
A computer-implemented method, comprising:
- receiving, at a primary database, a data modification request for modifying data in the primary database;
- modifying, based on the data modification request, second data in the primary database to first data;
- generating, based on the data modification request, a first log and a second log, wherein the first log is a simplified log comprising the first data;
- and wherein the second log is a complete log comprising the second data;
- performing persistence processing on the first log;
- and
- returning a modification result that corresponds to the data modification request.
A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
- receiving, at a primary database, a data modification request for modifying data in the primary database;
- modifying, based on the data modification request, second data in the primary database to first data;
- generating, based on the data modification request, a first log and a second log, wherein the first log is a simplified log comprising the first data;
- and wherein the second log is a complete log comprising the second data;
- performing persistence processing on the first log;
- and
- returning a modification result that corresponds to the data modification request.
A computer-implemented system, comprising:
- one or more computers;
- and
- one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
- receiving, at a primary database, a data modification request for modifying data in the primary database;
- modifying, based on the data modification request, second data in the primary database to first data;
- generating, based on the data modification request, a first log and a second log, wherein the first log is a simplified log comprising the first data;
- and wherein the second log is a complete log comprising the second data;
- performing persistence processing on the first log;
- and
- returning a modification result that corresponds to the data modification request.
