Dab tsi yog lub tswv yim los tswj cov kev txwv ntawm kev nkag mus ntawm cov peev txheej thaum ntau cov xov raug tua hauv Redis?
xauv Khaws qhov no hauv kev txiav txim siab, Redis ua li cas nrog 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 ).
Puas txhais tau tias yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas muab cov lus qhia rau kev siv cov khoom?
Kev them nyiaj yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas txiav txim siab seb qhov khoom siv tau li cas
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
