Ntau tshaj cov neeg siv khoom
Hauv Redis 2.6 qhov kev txwv no yog dynamic: los ntawm lub neej ntawd nws tau teem rau 10000 cov neeg siv khoom, tshwj tsis yog tias tau hais los ntawm maxclients cov lus qhia hauv Redis. conf.
Tsis tas li ntawd, muaj pes tsawg qhov kev thov tuaj yeem daws tau Redis?
Piv txwv li, siv pipelining Redis khiav ntawm nruab nrab Linux system ua tau xa txawm 1 lab thov ib ob, yog li yog tias koj daim ntawv thov tsuas yog siv O (N) lossis O (log (N)) cov lus txib, nws yuav tsis yooj yim mus siv ib yam nkaus. ntau CPU.
Tsis tas li ntawd, Redis ua li cas tswj kev sib raug zoo? Ib qho kev pabcuam ib leeg tuaj yeem muab tau sib npaug ntawm I / O qib los ntawm kev siv I / O (de) multiplexing mechanism thiab lub voj xwm txheej (uas yog dab tsi Redis ua ). Parallelism muaj tus nqi: nrog rau ntau lub qhov (sockets) / ntau cores koj tuaj yeem nrhiav tau ntawm cov khoom siv niaj hnub no, synchronization ntawm threads yog kim heev.
Tsis tas li ntawd, Redis kev twb kev txuas yog dab tsi?
Redis yog lub networked, nyob rau hauv-nco qhov tseem ceeb-nqi khw muag khoom nrog kev xaiv durability, txhawb ntau hom kev paub daws teeb cov ntaub ntawv. Redis tuaj yeem siv los siv ntau yam server sab architectural qauv. Koj cuam tshuam nrog Redis siv a tus neeg siv khoom / server raws tu qauv.
Redis sai npaum li cas?
Redis yog data structure server. Raws li qhov tseem ceeb ntawm cov ntaub ntawv khaws cia, Redis zoo ib yam li Memcached, txawm hais tias nws muaj ob qhov zoo ntawm qhov kev xaiv ntawd: kev txhawb nqa ntawm cov ntaub ntawv ntxiv thiab kev pheej hmoo. Tag nrho cov ntaub ntawv khaws cia hauv RAM, yog li ntawd Qhov ceev ntawm qhov system no zoo kawg nkaus, feem ntau ua tau zoo dua li Memcached.

Muaj pes tsawg tus yuam sij zoo ib yam tuaj yeem muaj phau ntawv txhais lus muaj Python?
Tus yuam sij txheeb xyuas lub ntsiab lus ntawm phau ntawv txhais lus, tus nqi yog cov ntaub ntawv sib raug rau tus yuam sij muab. Cov txiaj ntsig tseem ceeb yog qhov tshwj xeeb, i. e. tsis tuaj yeem muaj ob tus yuam sij zoo ib yam hauv phau ntawv txhais lus
Muaj pes tsawg qhov kev sib txuas tuaj yeem daws tau Redis?
Cov neeg siv ntau tshaj plaws Hauv Redis 2.6 qhov kev txwv no yog qhov muaj zog: los ntawm lub neej ntawd nws tau teem rau 10000 tus neeg siv khoom, tshwj tsis yog hais txog lwm yam los ntawm maxclients cov lus qhia hauv Redis. conf
Muaj pes tsawg txoj kev daws teeb meem tuaj yeem muaj teeb meem LP?
"Tsis yog, nws tsis tuaj yeem ua rau tus qauv LP kom muaj ob qho kev daws teeb meem zoo." Tus qauv LP tuaj yeem muaj 1 qhov kev daws teeb meem zoo tshaj plaws lossis ntau dua 1 qhov kev daws teeb meem zoo, tab sis nws tsis tuaj yeem muaj 2 qhov kev daws teeb meem zoo
Dab tsi yog qhov sib txawv ntawm kev sib txuas lus taw qhia thiab kev sib txuas tsis raug cai?
Qhov txawv: Kev sib txuas lus taw qhia thiab kev sib txuas tsis muaj kev sib txuas Kev sib txuas lus taw qhia kev sib txuas ua rau muaj kev sib txuas thiab xyuas seb cov lus puas tau txais lossis tsis tau thiab xa rov qab yog tias muaj qhov yuam kev tshwm sim, thaum qhov kev pabcuam tsis sib txuas tsis tau lees tias xa xov
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
