在Spark 应用中,OOM 问题一直比较突出,随着自身内存管理的不断发展和迭代已有明显改善,但在一些场景中仍然有这种风险。默认情况下,Executor 数据和计算过程所用内存资源主要在 JVM 管理的 On-Heap Unified Memory Pool 中,而 JVM 内对象通常是其原始数据的 2-5 倍,这种高内存占用主要因为封装为 JVM Object 时一...

(SR-B1)30. We therefore determined the effect of miR-205 expression or SQLE inhibition on cholesterol uptake by culturing the cells in the presence of cholesterol-2,3,4-13C3and detecting the fraction of cholesterol-13C3within the total cholesterol pool. This analysis showed that miR-205 ...
