We have two data centers, each of which has two redis instances. They are typically replicated as a chain.
NY1 (Master) --> NY2 (Slave) --> CO1 (Slave) --> CO2 (Slave)
NY is New York and CO is Colorado, our backup data center. To maintain global WAN bandwidth, we do not want CO1 and CO2 to connect to NY1. Rather, we need a chain configuration in which there is only one subordinate directly to the owner, and the rest are “subordinate subordinates.”
Can this type of replication be supported with Sentinel? Or should all slaves be the slave of the master, and not the slave of the slave?
