Hi Team, 1. Is kafka used in DR as well? > [dgl: No kafka in DR. DR uses local file system to store client date > until its delivered. It also uses mariadb to store provisioning data]
Kindly assist me understand the below If DR doesn't use kafka then how the partitioning of data and topics happens in DR? Kindly provide more info. Can you explain the internal call flow that DR does for a single file.txt transfer between two applications?
