mysql kev ua tau zoo

Cov ntaub ntawv kev tswj hwm toj roob hauv pes yog qhov nyuaj thiab hloov kho sai heev. Tsis muaj dab tsi hais txog cov kev hloov pauv no ntau dua li qhov tshwm sim ntawm 'super apps' - lossis cov ntawv thov uas ua tiav ntau lab ntawm cov neeg siv kev cuam tshuam ib pliag. Qhov Cuam Tshuam hauv Cov Ntaub Ntawv Loj thiab Huab, thiab nws tau pom tseeb tias cov tub lag luam e-lag luam xav tau lub sijhawm tshiab ntawm cov ntaub ntawv uas tuaj yeem ua tau zoo dua thiab ua kom nrawm dua.

Kev lag luam online tsis muaj ib qho kev hloov kho tshiab yuav zoo li khiav MySQL, cov chaw khaws ntaub ntawv nyuam qhuav hloov txij li qhov pib thaum xyoo 1995. Tom qab tag nrho, lub sijhawm "NewSQL" tsis dhau los ua ib feem ntawm cov lexicon digital kom txog thaum Matt Aslett, tus kws tshuaj ntsuam rau 451 Group. , coined nws hauv 2011.

Thaum MySQL yeej muaj peev xwm tswj tau qhov teeb meem zoo ntawm cov tsheb, vim tias kev lag luam txuas ntxiv mus, nws cov chaw khaws ntawv tej zaum yuav ncav cuag qhov siab tshaj plaws thiab nws lub vev xaib yuav nres kom ua haujlwm zoo. Yog tias koj tsis paub meej tias lub koomhaum npaj puas tau rau hauv NewSQL database, ntawm no yog tsib yam koj yuav tsis tau MySQL:

  1. Nyuaj los tuav nyeem, sau thiab hloov tshiab - MySQL muaj cov peev txheej tsis txaus. Raws li ntau thiab ntau cov neeg muas zaub ua tiav muas ntawm koj lub vev xaib, nws tsuas yog teeb meem ntawm lub sijhawm ua ntej koj lub chaw muag khoom. Ntxiv mus, raws li koj qhov load nce, thiab koj pom tias nws nyuaj los leg ntxiv cov ntawv nyeem thiab sau ntawv, koj yuav xav tau cov ntaub ntawv sib txawv. MySQL tuaj yeem nplai tau nyeem ntawm “tus nyeem cov qhev”, tab sis cov ntawv thov yuav tsum paub tias nyeem tsis yog asynchronous nrog tus sau-tus tswv. Piv txwv li, thaum tus neeg yuav khoom kho cov khoom tshiab hauv nws cov khoom lag luam hauv e-commerce, nws yuav tsum tau nyeem los ntawm tus sau-tus tswv. Yog tias tsis yog, koj muaj feem yuav tsis zoo-tau cog lus tias tsis raug. Yog tias qhov ntawd tshwm sim, koj yuav muaj qhov thaiv tsis zoo hauv qhov chaw ua tau phem: koj li e-commerce checkout kab. Ib qho kev khuam siab thaum kuaj tawm tuaj yeem ua rau cov tsheb laij tawm, lossis phem tshaj, koj yuav muag cov khoom muag uas koj tsis muaj, thiab yuav tsum cuam tshuam nrog cov neeg siv khoom tsis txaus siab, thiab muaj kev cuam tshuam tsis zoo rau kev tshaj tawm.
  2. qeeb analytics thiab qhia - MySQL databases tsis muab txhua lub sijhawm tiag tiag analytics peev xwm, tsis pub ua lawv muab kev txhawb rau lwm SQL tsim. Yuav kom daws tau qhov teeb meem no, ob qho tib si Multi-Version Concurrency Control (MVCC) thiab Cov Khoom Siv Ua Ntej Sib Tw (MPP) yuav tsum ua rau kev ua haujlwm loj heev vim tias lawv tso cai sau thiab analytics kom tshwm sim yam tsis muaj kev cuam tshuam, thiab siv ntau cov nodes thiab ntau lub pob rau ib lub nkees los ua kom muaj kev txheeb xyuas cov lus nug tau nrawm dua.

  3. Nquag downtime - MySQL cov chaw khaws cia ua nrog ib qho kev poob ntawm lub ntsiab lus, lub ntsiab lus yog tias ib qho tsis xws luag - xws li tsav, niam kab, lossis nco - tsis ua tiav, tag nrho cov ntaub ntawv yuav swb. Raws li qhov tshwm sim, tej zaum koj yuav ntsib kev poob qis, uas tuaj yeem ua rau poob nyiaj. Koj tuaj yeem siv rab ntaj thiab cov qhev, tab sis cov no tsis yooj yim thiab tsis tuaj yeem lis cov tsheb ntau. Cov ntaub ntawv teev tawm-teev khaws cia ntau cov ntawv luam ntawm koj cov ntaub ntawv, muab qhov ua tsis taus ua siab ntev thiab tswj cov haujlwm txawm tias thiab / lossis cov haujlwm disk poob.

  4. Cov nqi tsim tawm siab - Cov neeg tsim kho ua haujlwm nrog MySQL cov chaw khaws ntaub ntawv yuav tsum siv sijhawm ntau ntawm lawv lub sijhawm kho cov teeb meem kav dej lossis daws cov teeb meem tsis raug. Cov neeg tsim kho ua haujlwm nrog cov nplai-tawm ntawm lub chaw khaws ntaub ntawv yog pub dawb los hloov kev ua haujlwm ntawm kev tsim cov yam ntxwv thiab tau txais cov khoom lag luam kom nrawm dua. Raws li qhov tshwm sim, sijhawm rau kev lag luam qis dua thiab cov tuam txhab lag luam e-lag luam muaj peev xwm khwv tau nyiaj tau sai dua.
  5. Maxed tawm servers - Servers maxing tawm ntawm RAM rau ncua sij hawm, lossis nquag thawm hnub, yog qhov taw qhia tseem ceeb uas MySQL tsis tuaj yeem ua raws li kev lag luam nce ntxiv. Ntxiv cov khoom lag luam yog qhov kho tau sai, tab sis nws tseem kim heev thiab tsis yog yuav daws ntev. Yog tias cov koom haum tau siv qhov ntsuas tawm los ntsuas, cov ntaub ntawv tuaj yeem rov ua dua hla ntawm cov nodes, thiab raws li kev hloov pauv ntawm qhov ntau thiab tsawg, cov haujlwm yuav hloov mus rau lwm cov ntawm hauv cov hauv paus.

Hloov tuaj

Nws yog qhov tseeb, MySQL muaj nws cov kev txwv, thiab qhov tau muab sijhawm thiab kev loj hlob, txhua qhov MySQL database tau cuam tshuam rau cov kev ua tau zoo thiab teeb meem latency. Thiab rau lub vev xaib lag luam e-luam, cov kev ua tsis zoo yuav luag txhais ua qhov tsis tau nyiaj.

Tom qab tag nrho, nws yuav tsum tsis txhob tuaj ntau li qhov xav tsis thoob thaum ntawd tias lub thev naus laus zis uas tau tsim ob xyoo dhau los yog tawm tsam kom nyob rau hauv lub ntiaj teb digital ceev ceev niaj hnub no. Xav txog nws: yuav ua li cas cov programmers hauv 1995 paub tsuas yog qhov muaj zog hauv Is Taws Nem?
