CPU utilization high for 3 hours after COPY DIRECTs
I posted the problem before, but didn't get any answer. Since we have to resolve the issue, I post again.
I loaded data to Vertica using multiple (parallel) COPY DIRECTs (via a old version of Vertica connector). It took about 40 mins to finish this. But after it finished, from our Ganglia charts, we found the CPU utilization was still high for about 3 hours. What was the CPU doing? Can we speed up the computing needed after COPY DIRECTs? Thanks.
