The documentation and assumed correct functionality of --wait is:

setting --wait to false will cause the proxy to not wait for a result from both servers but return once it gets a result from the source sever

However, in

cassandra-proxy/src/main/java/com/microsoft/azure/cassandraproxy/Proxy.java

Line 228 in f184bca

ProxyClient client1 = new ProxyClient(commandLine.getOptionValue("source-identifier"), socket, protocolVersions, commandLine.getOptionValues("cql-version"), commandLine.getOptionValues("compression"), commandLine.getOptionValue("compression-enabled"),commandLine.getOptionValue("metrics"), commandLine.getOptionValue("wait"), null);

--wait is passed to the source ProxyClient, while the target ProxyClient gets the default value of true. In general the wait flag does not do what it's supposed to do (i.e. hangs).
