Abstract

The purpose of this application is to provide a method and device for cross-regional data transmission, by obtaining the metadata information sent by the corresponding client device, and sending the metadata information to the corresponding metadata transmission node device, wherein the metadata The information includes data replication progress information corresponding to the client device; acquiring data information to be forwarded corresponding to the metadata transmission node device, and pushing the data information to be forwarded to the corresponding client device, wherein the to-be-forwarded Forwarding data information includes data replication progress information of other client devices, effectively sending the metadata information sent by the corresponding client device to the corresponding metadata transmission node device; The forwarding data information is pushed to the corresponding client device, so as to realize metadata information synchronization.

Description

technical field [0001] This application relates to the computer field, and in particular to a technology for cross-regional data transmission. Background technique [0002] Data off-site replication is an important part of the Internet and is widely used in computer network environments. Data off-site replication includes synchronous replication and asynchronous replication. [0003] In the prior art, in scenarios with small delays (for example, from Hangzhou to Shanghai), the delay of synchronous replication is negligible and has little impact on applications. Among them, the industry standard for multi-site synchronous replication is the distributed consensus protocol (Paxos protocol). In asynchronous replication, the sender can continue to execute the logic of the sender (for example, non-relational database service (AWS DynamoDB Streaming)) without waiting for the receiver to confirm receipt; further, the asynchronous Replication provides data consistency maintenance f...
