Is there a memory limit for User Code Deployment on Hazelcast Cloud? (free version)

I'm currently playing with Hazelcast Cloud. My use case requires me to upload 50mb of jar file dependencies to Hazelcast Cloud servers. I found out that the upload seems to give up after about a minute or so. I get an upload rate of about 1mb a second, it drops after a while and then stops. I have repeated it a few times and the same thing happens.

Here is the config code I'm using:

Clientconfig config = new ClientConfig();
ClientUserCodeDeploymentConfig clientUserCodeDeploymentConfig = 
    new ClientUserCodeDeploymentConfig();

// added many jars here...  
clientUserCodeDeploymentConfig.addJar("jar dependancy path..");
clientUserCodeDeploymentConfig.addJar("jar dependancy path..");
clientUserCodeDeploymentConfig.addJar("jar dependancy path..");

clientUserCodeDeploymentConfig.setEnabled(true);
config.setUserCodeDeploymentConfig(clientUserCodeDeploymentConfig);

ClientNetworkConfig networkConfig = new ClientNetworkConfig();

networkConfig.setConnectionTimeout(9999999); // i.e. don't timeout
networkConfig.setConnectionAttemptPeriod(9999999); // i.e. don't timeout

config.setNetworkConfig(networkConfig);

Any idea what's the cause, maybe there's a limit on the free cloud cluster?

I'd suggest using the smaller jar because this feature, the client user code upload, was designed for a bit different use cases:

  1. You have objects that run on the cluster via the clients such as Runnable, Callable and Entry Processors.

  2. You have new or amended user domain objects (in-memory format of the IMap set to Object) which need to be deployed into the cluster.

Please see more info here.
