Ib Arbiter tshwj xeeb yog tsim los tsim kom muaj "kev tsis sib haum xeeb" lossis feem ntau ntawm ib sab kom tus thawj coj tuaj yeem raug xaiv nyob rau hauv rooj plaub no. Yog tias koj tau txais ib tus lej ntawm cov nodes ntawm ob sab MongoDB yuav tsis xaiv tus thawj thiab koj lub teeb yuav tsis lees txais cov ntawv sau.
Yog li ntawd, dab tsi yog qhov kev ua haujlwm ntawm tus arbiter node?
Arbiter nodes tsis txhob khaws tej ntaub ntawv; lawv muaj nuj nqi yog los muab kev pov npav ntxiv rau hauv cov kev xaiv tsa replica. Qhov tsawg kawg nkaus yuav tsum tau rau MongoDB pawg yog kom muaj tsawg kawg yog ob nodes : ib tug thawj thiab ib tug thib ob node . Cov txheej txheem replica tuaj yeem muaj txog 50 nodes , tab sis tsuas yog 7 tus neeg tuaj yeem xaiv tsa.
Tsis tas li ntawd, replication ua haujlwm li cas hauv MongoDB? MongoDB - Rov ua dua . Replication yog cov txheej txheem ntawm synchronizing cov ntaub ntawv hla ntau lub servers. Rov ua dua muab redundancy thiab nce cov ntaub ntawv muaj nrog ntau cov ntawv theej ntawm cov ntaub ntawv ntawm cov servers sib txawv. Rov ua dua kuj tso cai rau koj rov qab los ntawm hardware tsis ua hauj lwm thiab kev pab cuam cuam tshuam.
Tom qab ntawd, lub hom phiaj ntawm arbiter nyob rau hauv replica teeb yog dab tsi?
Arbiter . Ib arbiter tsis khaws cov ntaub ntawv, tab sis kom txog rau thaum lub cov arbiter mongod txheej txheem yog ntxiv rau lub replica teev , cov arbiter yuav ua zoo li lwm yam mongod txheej txheem thiab pib nrog ib teeb ntawm cov ntaub ntawv cov ntaub ntawv thiab nrog ib daim ntawv teev tag nrho.
Dab tsi yog replica hauv MongoDB?
A luam tawm teem rau hauv MongoDB yog ib pab pawg mongod txheej txheem uas tswj cov ntaub ntawv tib yam. Rov ua dua cov txheej txheem muab redundancy thiab muaj siab, thiab yog lub hauv paus rau tag nrho cov ntau lawm deployments. Ntu no qhia txog replication hauv MongoDB as well as lub Cheebtsam thiab architecture ntawm luam tawm teeb.

Dab tsi ntawm cov hauv qab no yog qhov zoo ntawm kev siv cov khoom siv pom kev hauv kev hais lus?
Qhov txiaj ntsig tseem ceeb ntawm kev siv cov khoom siv pom hauv koj cov lus hais yog tias lawv ua kom cov neeg tuaj saib muaj kev txaus siab, hloov kev mloog ntawm tus neeg hais lus, thiab ua rau tus neeg hais lus muaj kev ntseeg siab ntau dua hauv kev nthuav qhia tag nrho
Dab tsi yog qhov sib txawv loj ntawm kev txheeb xyuas qhov yuam kev thiab kev kho cov lej yuam kev?
Ob qhov kev tshawb nrhiav qhov yuam kev thiab kev kho qhov yuam kev yuav tsum muaj qee qhov ntawm cov ntaub ntawv rov qab xa mus nrog cov ntaub ntawv tiag tiag; kev kho yuav tsum muaj ntau tshaj li kev tshawb nrhiav. Parity bits yog ib txoj hauv kev yooj yim rau kev tshawb nrhiav qhov yuam kev. Ib qho parity me ntsis yog ib qho ntxiv me ntsis xa nrog cov ntaub ntawv uas tsuas yog 1-ntsis suav ntawm cov ntaub ntawv
Dab tsi yog qhov txawv ntawm cov neeg siv kev paub thiab kev paub ntawm cov neeg siv khoom?
User Experience (UX) cuam tshuam nrog tib neeg cuam tshuam nrog koj cov khoom thiab cov kev paub uas lawv tau txais los ntawm kev sib cuam tshuam. Customer Experience (CX), incontrast, encompasses tag nrho cov kev sib cuam tshuam ib tug neeg muaj nrog koj hom
Dab tsi yog kev siv cov ntawv cim kev cai li cas koj nkag mus rau hauv Apex cov chav kawm thiab hauv Visualforce nplooj ntawv?
Cov ntawv sau kev cai tso cai rau cov neeg tsim khoom tsim cov ntawv thov ntau hom lus los ntawm kev nthuav qhia cov ntaub ntawv (piv txwv li, pab cov ntawv lossis cov lus yuam kev) hauv tus neeg siv hom lus. Cov ntawv sau kev cai yog cov ntawv sau muaj txiaj ntsig uas tuaj yeem nkag tau los ntawm Apex cov chav kawm, nplooj ntawv Visualforce, lossis cov khoom siv xob laim
Dab tsi yog qhov tseem ceeb ntawm kev siv kev coj ncaj ncees rau cov ntaub ntawv kev ruaj ntseg?
Rau cov kws tshaj lij kev ruaj ntseg cov ntaub ntawv, muaj ob lub hom phiaj tseem ceeb thaum nws los txog rau cov ntaub ntawv tseem ceeb: tiv thaiv nws thiab paub txog nws qhov chaw. Cov koom haum tsis tuaj yeem xav tias cov ntaub ntawv raug cai lossis tau txais los ntawm kev coj ncaj ncees
