ok.tech: Ukudibana kukaCassandra

Ukusebenza nokugcinwa kwe-Apache Cassandra NoSQL?

NgoMeyi 23, i-Odnoklassniki imema abaphuhlisi abanamava kwiofisi yabo eSt dibana, ezinikele ekusebenzeni neApache Cassandra. Into ebalulekileyo ngamava akho noCassandra kunye nomnqweno wakho wokwabelana ngayo.
Bhalisela umsitho

Silungile waqala ukusebenzisa I-Apache Cassandra ngo-2010 ukugcina iireyithingi zeefoto. Okwangoku singabasebenzisi abakhulu be-Apache Cassandra kwi-RuNet kwaye yenye yezona zinkulu eYurophu. Sinamaqela angaphezu kwekhulu ahlukeneyo asetyenziselwa ukugcina ulwazi lwemveliso eyahlukeneyo - iiklasi, iingxoxo, imiyalezo, kunye nokulawula idatha yeziseko ezingundoqo - iibhloko zemephu ezinengqondo kwiidiski zogcino olukhulu lokubini - enye-ebandayo-ukugcinwa, ulawulo lwedatha yefu yangaphakathi ilifu elinye njalo njalo.

Lilonke, kwi Odnoklassniki ICassandra ilawula iipetabytes zedatha kumawakawaka eendawo. Ngeli xesha, siye saqokelela amava amakhulu ekulawuleni, ekuphuhliseni nasekusebenziseni izisombululo ezisekwe kwiCassandra kwaye saze saphuhlisa ezethu. eyakho idatabase yentengiselwano yeNewSQL.

Ngoku singathanda ukwabelana nawe konke oku - usebenzisa iimeko zokwenyani ukusuka ekusebenzeni kwaye ngaphandle kweemfihlo; Umcimbi uya kubanjwa ngendlela yengxoxo ephilayo phakathi kwabathathi-nxaxheba, oku kuthetha ukuba ingxoxo iya kuthatha ixesha elininzi. Iingcali zilungile bakulungele ukwabelana ngezimvo kunye neendlela zabo. Umsitho uya kusingathwa ngu Oleg Anastasyev и Alexander Khristoforov.

Iza kuba yintoni izihloko?

Ukuxhaphaza:

Makhe sijonge ulungelelwaniso oluqhelekileyo lweendawo zokuhlala kunye neqela kufakelo olwahlukeneyo lwemveliso. Siza kuxoxa ngendlela yokwandisa amaqela njengoko umthamo wedatha kunye nemithwalo inyuka kunye nendlela yokubuyisela iindawo ezingaphumeleliyo kunye nesiphumo esincinci kubaxhasi. Masabelane ngentlungu kwaye sicwangcise iraki edumileyo. Makhe sifumane indlela yokubeka iliso kumaqela ukuze siqonde kwangaphambili apho kwaye yintoni kanye kanye engasebenzi ngokuchanekileyo. Makhe sichukumise iingxaki zokuthumela iinguqulelo ezintsha zeCassandra.

Ukusebenza:

Masizame ukuqonda ukuba zeziphi iimetrics ekufuneka zijongwe kwaye yintoni enokulungiswa ukwenza iimetrics zibengcono. Makhe sijonge ukuba siphinde siqeqeshe okanye hayi kwaye ukuba kunjalo, njani. Siza kuchonga imiqobo kuyilo kunye nokuphunyezwa kweCassandra kwaye sijonge amaqhinga athile obunjineli ukuze sisebenze malunga nawo. Makhe sichukumise ulungiso oluqhelekileyo olubuhlungu kunye nokudibanisa ngaphandle kokuthotywa kokusebenza.

Ukunyamezela iimpazamo:

I-Hardware ayihlali ngonaphakade, ngoko ke iingozi zenzeke ngamaxesha onke, kwaye isandla somntu osebenza naye sinokuthuthumela kwaye siya kususa izinto ezingeyomfuneko, ngoko siza kuxubusha ukubuyisela emva kokungaphumeleli kweediski, oomatshini okanye amaziko edatha, kunye nokubuyela umva ngokuhambelana. chaza kwii-backups xa kukho iimpazamo zabasebenzisi.

Bhalisa ngoku kwaye uxelele abahlobo bakho kunye noogxa bakho malunga nomsitho.
