Hi Gurus,
I have a grid with 6 nodes and 4 caches. One of the caches is partitioned
(offheap) and others are replicated (onheap). I run SQL queries on this grid
from my application.
When I run my application using one user, things work good. But, when I run
my application using 48 concurrent users, there are errors. Each new user
joins the grid as a client and runs SQL queries. -
Exception in thread "main" javax.cache.CacheException: Failed to run reduce
query locally.

Can you please guide here? Do you have any benchmarks on using ignite with
several client nodes joining the grid concurrently?
Thanks,
Arthi
