We do mirroring across data-centers (but in the same continent). You should basically set a high fetch size and socket buffer size in such scenarios.
In general, you should set a high value for the socket buffer size on the consumer configuration (socket.buffersize) and the source cluster's broker configuration (socket.send.buffer). Assuming you are using the high-level consumer, the fetch size (fetch.size) should be higher than the consumer's socket buffer size. Note that the socket buffer size configurations are a hint to the underlying platform's networking code. If you enable trace logging, you can check the actual receive buffer size and determine whether the setting in the OS networking layer also needs to be adjusted. Likewise, you will need to use higher connection/session timeouts for zookeeper and set your offset commit intervals to be fairly large.
