Since sg-replicate acts as client, having multiple instances will do the same job(_changes) which can be duplicate to server side. hence running multiple instance of same sg-replicate configuration will cause overhead(reads, view reads) on couchbase.
and also , though we have option to select filter of each sg-replicate(different config) instance but how do i overcome the redundancy in case of failure of sg-replicate.
any better approach to run sg-replicate(same configuration) in multiple instances.
