Hi , 

Do we have a streaming version of Logistic Regression in Spark ? I can see its there for the Linear Regression.

Has anyone used logistic regression on streaming data, it would be really helpful if you share your insights on how to train the incoming data.

In my use case I am trying to use logistic regression for click through rate prediction using spark. Reason to go for online streaming mode is we have new advertisers and items coming and old items leaving.

Any insights would be helpful.
