If I am synchronizing 2 datacenters using the Aerospike XDR product, what happens if the network connection is severed? Will I lose data or will it be stored somewhere?
You will not lose data. Aerospike XDR is configured with a log file that stores the records to transfer to the other data center. In the event that the connection is down, the log will increase. Aerospike XDR only stores a hash of the key for each object rather than the entire object in order to conserve space. The amount of space allocated is configurable and can be many days long. Aerospike does not have high performance demands on access to this file, so you may choose to use standard rotation hard disk.
