Writing to two different geographical locations without using XDR

Hello…

We are using the community Edition of aerospike. Currently we have our aerospike server in US and are planning to host a server in Singapore too. Now we want to write the records to both the servers with minimum latency. Is it possible to write to both the servers simultaneously without using XDR with less latency cost?? Also roughly how much latency will be there if we go with this approach ?
