Hello, guys. I've finish implementation of IGNITE-7337 [1]
Support of saving data frame to Ignite. Please, review. Valentin, I think it would be better to review this task prior IGNITE-7077 (query optimization). Because, this issue is relatively smaller and easier to review. And, from my point of view, adds some valuable feature to project.
