Hi Team,

We have an XDCR requirement as illustrated in the diagram above. Does CB support this type of topology? If it does, how does CB handle updates? Specifically, if a document is modified in Site 1, will the updated version be available simultaneously across all three sites, or will there be a delay in updating each site?

Thanks,
Debasis

I don’t find any restrictions on such an architecture in the documentation. You can confirm by creating test clusters and observing

@mreiche Thanks for confirmation. If we configure XDCR from site A–> site B and
site A–> site C . When a document is updated on Site A, it is replicated to Site B and Site C independently, each experiencing its own network latency. Alternatively, the replication may occur sequentially. Please help me to understand on this.

Thanks,
Debasis

The XDCR documentation is the best place to understand the behavior of XDCR. It is best not to make assumptions about behavior that is not described in the documentation.
