Khoom cia yog tib lub thev naus laus zis uas tso cai rau pej xeem huab, thiab muab cov kev pabcuam rau cov neeg muab kev pabcuam kom tau txais txiaj ntsig zoo, thiab muaj txiaj ntsig zoo. scalable ib puag ncig. Yam khoom khw muag khoom ua tiav lawv scalability los ntawm decoupling cov ntaub ntawv kev tswj hwm los ntawm kev tswj hwm qis qis.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov khoom khaws cia zoo rau?
Yam khoom khw muag khoom pab koj tswj cov ntaub ntawv tsis tsim nyog los ntawm kev tso cai rau koj tag cov ntaub ntawv nrog cov metadata kev cai uas piav txog lawv cov ntsiab lus. Qhov no tso cai rau koj taug qab thiab ntsuas cov ntaub ntawv yam tsis tas yuav tsum muaj cov software sab nraud lossis databases. Tag nrho koj cov ntaub ntawv yog tus kheej piav qhia, uas qhib ib qho kev muaj peev xwm tshiab rau cov ntaub ntawv txheeb xyuas.
Dab tsi yog qee qhov kev siv rau kev khaws khoom? Common use case for Object Storage:
- Kev puas tsuaj rov qab - Thaub qab thiab Archiving.
- Static web site hosting thiab static content distribution.
- Document Store thiab cov ntaub ntawv sib koom.
- Cov ntaub ntawv loj analytics.
Hauv qhov no, cov khoom khaws cia ua haujlwm li cas?
Khoom cia yog data khaws cia lub tswv yim uas faib cov ntaub ntawv rau hauv cov chav sib txawv, lossis khoom ,qu yog khaws cia nyob rau hauv ib lub tsev khaws khoom cais nrog rau tag nrho cov metadata cuam tshuam thiab tus cim kev cai.
Qhov txawv ntawm cov khoom thiab cov ntaub ntawv khaws cia yog dab tsi?
Qhov ntau khoom hauv ib khoom cia system yog khaws cia tag nrho cov muab khaws cia disks. Nyob rau hauv nws daim ntawv ntshiab khoom cia tuaj yeem "tsuas yog" txuag ib qho version ntawm ib ntaub ntawv ( khoom ). Lub ntsiab qhov sib txawv ntawm lwm lub tswv yim yog tias cov khoom yog tswj los ntawm daim ntawv thov nws tus kheej uas txhawb Khoom cia.

Vim li cas peb siv cov txheej txheem khaws cia hauv MySQL?
Cov txheej txheem khaws cia pab txo cov tsheb khiav hauv lub network ntawm cov ntawv thov thiab MySQL Server. Vim tias tsis xa ntau cov lus SQL ntev, cov ntawv thov yuav tsum xa tsuas yog lub npe thiab cov txheej txheem khaws cia
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
Cov ntaub ntawv khaws cia hauv cov khoom siv sib nqus li cas?
Magnetic storage lossis magnetic recording yog qhov khaws cia ntawm cov ntaub ntawv ntawm qhov nruab nrab magnetized. Sib nqus cia siv cov qauv sib txawv ntawm magnetisation nyob rau hauv cov khoom siv magnetisable los khaws cov ntaub ntawv thiab yog ib daim ntawv uas tsis yog-volatile nco. Cov ntaub ntawv nkag mus siv ib lossis ntau dua nyeem / sau taub hau
Cov piv txwv ntawm cov khoom siv khaws cia tseem ceeb yog dab tsi?
RAM (random nkag tau lub cim xeeb) thiab cache yog ob qho tib si piv txwv ntawm lub chaw cia khoom. Daim duab qhia peb hom kev khaws cia rau cov ntaub ntawv hauv computer. Thawj qhov chaw khaws cia qhov tseem ceeb sib txawv los ntawm lwm tus yog tias nws nkag tau ncaj qha los ntawm CPU, nws tsis hloov pauv, thiab nws tsis tuaj yeem tshem tau
