Abstract

A method, apparatus, apparatus, and storage medium for data synchronization between clusters are disclosed. The method includes reading a target message offset of a first partition of a first topic ofa target cluster; Comparing a target message offset with an oldest message offset of a second partition of a second subject of the source cluster, the second subject having the same subject name as the first subject and the first partition having the same partition sequence number as the second partition; If the target message offset is less than the oldest message offset, filling the data into the first partition; And synchronizing the master copy of the second partition to the first partition. According to the technical proposal of the embodiment of the present application, the problem thatthe subject partition data of the source cluster and the target cluster are unevenly distributed in the prior art is overcome by data filling processing.

Description

technical field [0001] The present application generally relates to the technical field of big data processing, specifically relates to the technical field of kafka, and especially relates to a data synchronization method, device, equipment and storage medium between clusters. Background technique [0002] With the development of big data, such as large-scale parallel processing databases, data mining, distributed file systems, distributed databases, cloud computing platforms, etc. are constantly updated. [0003] As a high-throughput distributed publish-subscribe messaging system, Kafka supports the distinction of messages through Kafka servers and consumer clusters. There is an uneven distribution of topic partition messages of the target cluster and topic partition messages of the source cluster using existing synchronization tools between consumer clusters, for example, the MirrorMaker tool. Contents of the invention [0004] In view of the above defects or deficienci...
