Hi guys,
I have problem witch mergeout in my vertica cluster. Once a day start big mergeout at the same time and working at 3-4 hours. I don't understand why it happens?
Statistic mergeout:
DATE_TRUNC min_ros_gb max_ros_gb sum_ros_gb count_merg ------------------- ---------- ---------- ---------- ---------- 2018-02-28 13:00:00 42.72 43.12 171.96 4 2018-02-28 12:00:00 26.95 43.25 506.74 14 2018-02-28 11:00:00 27.01 27.24 162.85 6 2018-02-28 05:00:00 129.69 129.82 259.51 2 2018-02-28 04:00:00 129.53 129.79 1296.59 10 2018-02-28 03:00:00 84.69 84.92 1018.06 12 2018-02-27 23:00:00 54.33 54.33 54.33 1 2018-02-27 22:00:00 54.31 54.61 326.70 6 2018-02-27 21:00:00 35.71 54.66 482.44 11 2018-02-27 20:00:00 36.00 36.21 216.71 6 2018-02-27 14:00:00 39.61 39.68 79.29 2 2018-02-27 13:00:00 39.54 39.76 158.68 4 2018-02-27 12:00:00 26.28 41.05 199.38 7
Every day at 3.00 - 6.00 running big mergeout. Objects are the same - two big flex table.

hey sergey , how's your tm resource pool values look like? Have you tried to increase the memorysize of tm pool?
Hi, caliskurahmet
My tm pool:
I has increased the memorysize to 8G - no effect.
