Hi
I am doing a insert test with 9 nodes, the command:
> stress.py -n 1000000000 -t 1000 -c 10 -o insert -i 5 -d
> 10.0.0.1,10.0.0.2.....
and 5 of the 9 nodes were cashed, only about 6'500'000 rows were inserted
I checked out the system.log and seems the reason are 'out of memory'. I
don't if this had something to do with my settings.
Any idea about this?
Thank you, and the following are the errors from system.log
