Yintoni umahluko phakathi kwetafile yedatha yeMySQL yeMyISAM kunye nohlobo lwe-InnoDB?Thelekisa ukuba yeyiphi engcono

• In MySQL Xa udala itafile kwi, ungakhetha injini yokugcina.
• Kukho iinjini ezininzi zokugcina ezahlukeneyo, kodwa ezona zisetyenziswa ngokuqhelekileyo yiMyISAM kunye ne-InnoDB, zonke zahlukile MySQL Inguqulelo yenjini yokugcina engagqibekanga.
• Ukuba akukho njini yogcino echaziweyo xa itheyibhile yenziwe, inguqulelo yeMySQL yenjini engagqibekanga iyasetyenziswa.
• Kwiinguqulelo ezingaphambi kwe-MySQL 5.5.5, i-MyISAM yayingagqibekanga, kodwa kwiinguqulelo emva kwe-5.5.5, i-InnoDB yayingagqibekanga.

MySQL databaseUmahluko phakathi kohlobo lweMyISAM kunye nohlobo lwe-InnoDB

• I-InnoDB intsha, iMyISAM indala.
• I-InnoDB inzima ngakumbi, ngelixa i-MyISAM ilula.
• I-InnoDB ingqongqo malunga nokuthembeka kwedatha, ngelixa i-MyISAM ithambile ngakumbi.
• I-InnoDB isebenzisa ukutshixeka komgangatho womqolo wokufakwa kunye nohlaziyo, ngelixa i-MyISAM isebenzisa ukutshixa kwenqanaba letafile.
• I-InnoDB inentengiselwano, iMyISAM ayinayo.
• I-InnoDB inezitshixo zangaphandle kunye nezithintelo zobudlelwane, ngelixa i-MyISAM ingenayo.
• I-InnoDB inokuqina okungcono kokuphahlazeka, ngelixa i-MyISAM ayikwazi ukubuyisela ingqibelelo yedatha xa kwenzeka ukuphazamiseka kwenkqubo.
• I-MyISAM inezalathisi zokukhangela ezipheleleyo, ngelixa i-InnoDB ingenayo.

Iinzuzo zodidi lwe-InnoDB

I-InnoDB kufuneka ibeke phambili ukuthembeka kwedatha kuba ilawula ingqibelelo yedatha ngokusebenzisa imiqobo yobudlelwane kunye nokuthengiselana.

Ikhawuleza kwiitheyibhile zokubhala kakhulu (faka, uhlaziyo) kuba isebenzisa ukutshixeka komgangatho werowu kwaye igcina kuphela utshintsho kumqolo ofanayo owawufakelwe okanye uhlaziyiwe.

Iintswelo zodidi lwe-InnoDB

• Ngenxa yokuba i-InnoDB iphatha ubudlelwane phakathi kweetafile ezahlukeneyo, abalawuli bedathabheyisi kunye nabaqulunqi be-schema kufuneka bachithe ixesha elininzi beyila iimodeli zedatha ezinzima kuneMyISAM.
• Sebenzisa izixhobo ezininzi zenkqubo ezifana ne-RAM.
• Ngapha koko, abantu abaninzi bacebisa ukucima injini ye-InnoDB emva kokufaka i-MySQL ukuba awuyifuni.
• Akukho salathisi sokubhaliweyo esipheleleyo

Izinto ezilungileyo zeMyISAM

• Kulula ukuyila kunye nokudala, ngoko ke ilungele ngakumbi abaqalayo.
• Sukuba nexhala malunga nobudlelwane bangaphandle phakathi kweetafile.
• Ngokubanzi ngokukhawuleza kune-InnoDB ngenxa yesakhiwo esilula kunye nexabiso eliphantsi lesixhobo somncedisi.
• Isalathisi sokubhaliweyo okupheleleyo.
• Ingakumbi iluncedo ekufundeni-nzulu (khetha) iitafile.

Iingxaki zohlobo lweMyISAM

• Akukho mfezeko wedatha (umzekelo, imiqobo yobudlelwane) etshekishwayo, nto leyo eyandisa uxanduva kunye nentloko kubalawuli bedatabase kunye nabaphuhlisi bezicelo.
• Iitransekshini eziyimfuneko kwidatha-ebaluleke kakhulu yezicelo ezifana nokubhankisha azixhaswa.
• Iyacotha kune-InnoDB kwiitafile ezifakwa rhoqo okanye ezihlaziyiweyo kuba yonke itafile itshixiwe kulo naluphi na ukufakwa okanye uhlaziyo.

Uhlobo lwe-MyISAM vs. Uhlobo lwe-InnoDB, yeyiphi engcono?

I-InnoDB ifaneleka ngakumbi kwiimeko ezinzima zedatha ezifuna ukufakwa rhoqo kunye nohlaziyo.

I-MyISAM, kwelinye icala, yenza ngcono kwizicelo ezingathembeli kakhulu kwimfezeko yedatha, ngokufuthi ukukhetha nokubonisa idatha.

1. Ukuba ufuna ukuxhasa intengiselwano, khetha i-InnoDB, kwaye ukhethe i-MyISAM ukuba awuyidingi intengiselwano.
2. Ukuba uninzi lwemisebenzi yetafile yimibuzo, khetha iMyISAM, kwaye ukhethe i-InnoDB yokufunda nokubhala.
3. Sukukhetha i-MyISAM ukuba i-crash yenkqubo yenza ukubuyisela idatha kunzima kwaye kuyabiza.
