求助R语言字符串分割问题

Question

如题所述

Answer 1

可以参考使用Redis特有内存模型前后的情况对比：

VM off: 300k keys, 4096 bytes values: 1.3G used
VM on: 300k keys, 4096 bytes values: 73M used
VM off: 1 million keys, 256 bytes values: 430.12M used
VM on: 1 million keys, 256 bytes values: 160.09M used
VM on: 1 million keys, values as large as you want, still: 160.09M used
