wangkang commented on KUDU-2639:
--------------------------------

I know peak and the difference in total consumption was advanced memory write data, then release so down, but I want to ask is, if I want to insert a large amount of data such as 10 g, then the server at this time of the peak is bigger, lead to consumption at that point is big, more than a memory hard limit service is not available

> When I insert 1.2 gigabytes of data, the server value keeps increasing, reaching a peak of 3.2 gigabytes and the memory utilization reaches 48%. So if I want to insert more, is it possible to cause memory usage limit? How to avoid this situation? Can the memory used by this server be cleared manually?
