I'm feeling miserable that I totally forgot about the deadline to request the certification voucher :(

Great article! 
Thanks for introducing ngrok. Never heard of ngrok before, now I'll take a closer look at it.

Hi @John Lisa 

If you need to extract a large amount of data, the other options DBeaver and Datagrip, are better choices.

I usually use DBeaver to deal with situations like this. 

Because using JDBC, you don't have the Gateway Time-out problem.

Thanks for sharing your experience. 

Indeed this global scenario brought a lot of challenges for those who weren't a "work from home" experts.

For me, staying work from home since last March showed me that when working from home, we need to face different challenges. In my case, with two children, I also need to be a teacher, help with Math class lessons, I need to change diapers, prepare baby bottles, preparing lunch/snacks /dinner, and last but not least, work! 

Managing and balance everything it's the great mystery of all. laugh

I was curious about the error mentioned in the article/images and try to create a persistent class using IRIS Studio. I got the same error. 

@Eduard Lebedyuk , let me ask you a question about IntegratedML as a rookie in this field. 

Using the example of 6400 columns that you mention, can I use the IntegratedML to create a model, train it through PythonGateway? Or IntegratedML only can be used in persistent classes inside IRIS?
