Hi,

Thanks for this, but I don't think that the method signature matches your changes. The interface is to send a random record, which implies that it will have a random partition key. If you set the same partition key on every record, then you will only target one shard and a single KCL process thread. By sending differing values within the User Records, you allow the Aggregation Code to generate the correct protocol buffer encoded Map of messages, which should then spread across many consumers.

Thx,

Ian
