Synchronisation

A Datanode can replicate Chain data with other Datanodes. Each Chain can be setup using a replication roles like :

  • Read
  • Read/Write
  • Master

1 datanode can have multiple chains and the replication is done on Chain level.

Situation: 1

2 DataNodes (X,Y) and 2 chains (finance, logistic)

DataNode X:
Chain Finance: Master
Chain Logistic: Read
DataNode Y:
Chain Finance: Read
Chain Logistic: Master

 

 

Situation: 2

There is even an (enterprise) option where you can have a Master – Master situation, per chain !

Compared to situation1 we now make the chain Logistic on Datanode Y Master as well.

DataNode X:
Chain Finance: Master
Chain Logistic: Master
DataNode Y:
Chain Finance: Read
Chain Logistic: Master
