The way that clients operate is quite different in AI3. You can't assume
the same thick/thin distinction.
There are two answers to your question:
1. Ignite 2 will continue to be available. Version 3 is a big update and
it's unlikely that everyone will move over on day 1. So if you like AI2,
it's safe to use it
2. Ignite 3 is currently in beta, so no one can give you definitive
answers. However, the goal is that AI3 will support the same (and more!)
workloads as 2, although the way you achieve the functionality may differ

For now it does not have any of that. KeyValueView [1] is a table
access interface in Ignite 3 that is most similar to a "cache".
