Sure, this is possible. You need to use Server-side Push.

However, there are a couple of things you need to consider

  • You may have to limit your update rate. Don't expect to be able update your Grid say 10 times per second. Conflating your updates is not something Vaadin can do for you, so you'll have to do that yourself before you hit Vaadin. If you absolutely know that yuur update rate is low (and will never burst) then you can disregard this bullet.
  • You'll most likely need some kind of visual indication in the cells that have changed. Perhaps this can help you.
