I have a use case where I need to create a Solr 6.6 cluster in AWS. The collection will have a replication factor of 3 and needs to be in 3 different Availability Zones.
I’ve read the documentation on Rule-based Replica Placement but it doesn’t seem to be very clear how I would tag servers so at collection creation time the replication would be divided into the 3 Availability Zones. The documentation mentions a snitch class called EC2Snitch “snitch=class:EC2Snitch”. Is this snitch aware of where the servers are and will Automatically place the replicas a cross the 3 Zones? I have 90 servers, 30 in each Zone with a replication factor of three. How can I force Solr to create the replicas in the 3 zones? Is it rule=replica:1,host:*-az1&rule=replica:2,host:*-az2&rule=replica:3,host:*-az3 Thanks for the help.
