James comment:
So that's with a 4GB heap allowing Phoenix to use 50% of it. With a pretty
narrow table: 3 KV columns of 30bytes. Topping out at 250K is a bit low. I
wonder if our memory estimation matches reality.
What do you think Maryann?
How about filing a JIRA, Mujtaba. This is a good conversation to have on the
dev list. Can we move it there, please?
