当我利用红利·赫梅特里娜指挥系统在生产环境中检索数据时,如果指挥中包含的钥匙数超过10 000件,而且请求量很大,则该指挥中心使用红星机的情况急剧上升。
我很想知道这一现象背后的具体原因,因为从散列表中检索数据应为奥(1)时间费用。
if the number of keys included in the command exceeds 10,000
如果我能正确理解,你就是指红利运动的田地数。
从原表检索数据应为O(1)
是的,从原桌上获得单一领域的时间复杂性是O(1)。 然而,你正在恢复10 000个田地,时间复杂度应当比奥(1)大10 000倍。
HMGET是一种缓慢的指挥,当时你需要把许多领域赶走。 它阻止了Redis,并且你应当谨慎地使用它。
