阅读Redis信息(Reading Redis Info)

我的笔记本电脑只有8GB内存,我试着对我的应用程序进行压力测试,该应用程序大量使用Redis。 当我查看INFO输出时,我无法弄清楚如何使用内存为31.83GB。 Rdb转储只有300 MB。

# Memory
used_memory:34177666096
used_memory_human:31.83G
used_memory_rss:412901376
used_memory_peak:34175483600
used_memory_peak_human:31.83G
used_memory_lua:31744
mem_fragmentation_ratio:0.01
mem_allocator:libc

问题:

为什么Rdb转储如此之小且used_memory_human如此之大? 如何识别实际内存使用情况(INFO显示不同的内容)?


My laptop has only 8GB RAM, I tried to stress test my app, which uses Redis heavily. When I looked at INFO output I couldn't figure out how used memory can be 31.83GB. Rdb dump is only 300 mb.

# Memory
used_memory:34177666096
used_memory_human:31.83G
used_memory_rss:412901376
used_memory_peak:34175483600
used_memory_peak_human:31.83G
used_memory_lua:31744
mem_fragmentation_ratio:0.01
mem_allocator:libc

Questions:

Why Rdb dump is so small and used_memory_human is so big? How to identify actual memory usage (INFO shows something different)?

最满意答案

你需要forceDelete方法

Model::where('condition')->where('may be other condition')->forceDelete();

或特定的模型实例:

$modelInstance = Model::find($id);
$modelInstance->forceDelete();

You need forceDelete method

Model::where('condition')->where('may be other condition')->forceDelete();

or on particular model instance:

$modelInstance = Model::find($id);
$modelInstance->forceDelete();
