Vertica cluster(DC) to cluster(DR) replication , may be using streaming technology
I have a customer setup which is of 3 node cluster. They would like to setup a DR setup which is exact replica setup of production. I am looking for a replication solution from production cluster to DR setup so that there will be no event loss.
AFAIK, I can use vbr tool supported by Vertica to replicate the entire cluster. However, I am skeptical about the data loss part. In what frequency will it sync the data? Does it use some kind of kafka streaming so that we set offset and don't loss any data? I don't know it's internal how it works.
The other option I found in vertica doc, we can use kafka for data replication using inbuilt kafka package in vertica. Can someone help me to understand how it work?
Thanks in advance,
