Hi , I have two usecases
1. I have two streams which `leftSource` and `rightSource` which i want to join without partitioning over a window and find the difference of count of elements of leftSource and rightSource and emit the result of difference. Which is the appropriate join function ican use ? join/cogroup/connect. 2. I want to replicate the same behaviour over a keyed source. Basically leftSource and rightSource are joined by a partition key. Plz let me know which is the appropriate join operator for the usecase -- *"The information contained in this e-mail and any accompanying documents may contain information that is confidential or otherwise protected from disclosure.
