Unbalanced CPU consumption
I recently setup a 3 nodes cluster, created my data model, without applying any particular tuning of any sort, just using all default database settings, no additional projections.
I am now running regular queries on this cluster, and I am observing that, out of my 3 nodes, only 2 seems quite heavily busy (between 400% and 500% CPU) when queries are running, while the 3rd one is almost idle (never more than 100%).
This is has been true for the last 12 hours.
I used to run this same set of queries on this same data model before, on other clustesr, and never observed this.
Any idea about possible reasons for this ?
Thans for helping
