Zimbalwa iintsuku ezidlulileyo I-Apache Software Foundation ibhengeze ukukhutshwa kwenguqulelo entsha yeApache Cassandra 4.0 oko ikukuthi Inkqubo yolawulo lwedatha ehanjiswayo Yeyodidi lweenkqubo ze-SQL kwaye yenzelwe ukwenza isitokhwe esinokuthenjwa nesinokuthenjwa semali enkulu yedatha egcinwe ngendlela yoluhlu olunxulumene noko.
Le nguqulo intsha ye-Apache Cassandra 4.0 ithathwa njengenguqulelo ezinzileyo ukuze isetyenziselwe ukuthunyelwa kwemveliso kwaye sele kuvavanyiwe kwizakhiwo zeAmazon, iApple, iDataStax, i-Instaclustr, iland kunye neNetflix enamaqela angaphezu kwe-1000.
Iimpawu ezintsha zeApache Cassandra 4.0
Le nguqulo intsha ye I-Apache Cassandra 4.0 imele phantse i-1,000 yokulungisa i-bug, ukuphuculwa, kunye neempawu ezintsha Ezizinto zilandelayo
- Ukunyusa isantya kunye nokusasazeka: idlulisa idatha ukuya kuthi ga kwi-5x ngokukhawuleza ngexesha lesikali sokusebenza kunye ukuya kuthi ga kwi-25% yokusebenza okukhawulezileyo kufundo kunye nokubhala, ukubonelela ngolwakhiwo olugqithisileyo, ngakumbi kwilifu kunye nokusasazwa kweKubernetes.
- Ukuphuculwa kokuhambelana: igcina ukuphindaphindeka kwedatha ukuvumelanisa nokwenza ulungiso olongezelelekileyo lokusebenza ngokukhawuleza nangokufanelekileyo nangokungaguquguquki phakathi kweempendulo zedatha.
- Ukuphuculwa kokhuseleko kunye nokuqwalaselwa: umzila wophicotho-zincwadi ulandela ukufikelela komsebenzisi kunye nomsebenzi onefuthe elincinci ekusebenzeni komthwalo womsebenzi. Ukufakwa ngokutsha kunye nokudlala kwakhona kwenza uhlalutyo kwimithwalo yomsebenzi ukunceda ukuqinisekisa ukhuseleko kunye nokuthotyelwa kolawulo lwe-SOX, i-PCI, i-GDPR okanye ezinye iimfuno.
- Useto olutsha lokumisela: iimethrikhi zenkqubo eveziweyo kunye noseto loqwalaselo zibonelela ngokuguquguquka kwabaqhubi ukuqinisekisa ukuba banokufikelela ngokulula kwidatha eyandisa ukuthunyelwa.
- Ubuncinci bokugqibela: Umqokeleli wenkunkuma amaxesha okuphumla ancitshisiwe ukuya kwi-millisecond ezimbalwa ngaphandle kokuthotywa kwexesha njengoko ubukhulu bemfumba bonyuka.
- Uxinzelelo olungcono: Ukuphucula ukusebenza koxinzelelo kunciphisa uxinzelelo olungafunekiyo kwindawo yediski kwaye kuphucula ukusebenza kokufunda.
Ukongeza koku, kuyacaciswa ukuba Ukuphicothwa kwelog yokuxhasa ukulandelela imisebenzi yokuqinisekisa Abasebenzisi kunye nayo yonke imibuzo ye-CQL eyenziwe, kunye ne ukukwazi ukugcina irekhodi epheleleyo yezicelo, Ukuvumela ukuba ugcine zonke izicelo kunye nokuphendula kwezithuthi.
Ngokufanayo, ngokunjalo Ukhetho lokulinga ukuthelekisa yonke imithi yeMerkle lubonakalisiwe. Umzekelo, ukuvumela ukhetho kwiqela kunye neendawo ezi-3, apho iimpendulo ezimbini ezifanayo kwaye enye iphelelwe lixesha, kuya kukhokelela ekuhlaziyweni komzobo ophelelwe lixesha kusetyenziswa ikopi yokusebenza kwale replica yangoku.
Njengokuba, Inkxaso eyongeziweyo yeetafile ezibonakalayo ezingabonisi idatha egcinwe kwii-SSTables, kodwa ulwazi luboniswe nge-API (ukusebenza kweemetrikhi, ulwazi loqwalaselo, umxholo we-cache, ulwazi malunga nabaxumi abaxhunyiwe, njl.
Ukugcinwa kokucinezelwa kokusebenza kuphuculwe ukunciphisa ukusetyenziswa kwediski kunye nokuphucula ukusebenza kokufunda.
Kwelinye icala, kuyacaciswa ukuba yongeze inkxaso yovavanyo lokuphindaphindeka okwethutyana kunye neeQoram ezitshiphu. Ukuphindaphindwa okwethutyana akuyigcini yonke idatha kwaye kusetyenziselwa ukubuyisela kwimeko yesiqhelo ukungqinelana neempendulo ezizeleyo. Iikhoramu ezingasindiyo zibhala zilungiselela ezingabhaleli ukuphindaphindwa okwethutyana de kubekho iseti eyaneleyo yeempendulo ezizeleyo.
Ngokuphathelene nedatha enxulumene nendawo yesitshixo senkqubo (inkqubo. *), Oku ngoku kulawulo lokuqala ngokungagqibekanga endaweni yokuba kusasazwe phakathi kwazo zonke iinkcukacha zedatha, ukuvumela indawo ukuba ihlale isebenza kwimeko yokungaphumeleli enye yeediski ezongezelelweyo.
De Olunye utshintsho ezibalaseleyo:
- Inkxaso yovavanyo lweJava 11 yongezwa.
- Yongezwe inkxaso yokusebenza kwezibalo kwimibuzo ye-CQL.
- Umyalelo we "nodetool cfstats" wongeze inkxaso yokuhlela ngokwezixhobo ezithile kunye nokunciphisa inani lemigca ebonisiweyo.
- Useto lubonelelwe ukuthintela unxibelelwano lwabasebenzisi kumaziko athile edatha kuphela.
- Yongeze amandla okunciphisa umda (ikhephu yokuhamba rhoqo) yokusebenza kunye nokucima iifoto.
- Inkxaso yePython 3 iyenziwa kwi-cqlsh kunye ne-cqlshlib (inkxaso ye-Python 2.7 isagcinwa).
Ekugqibeleni, ukuba unomdla wokwazi okungakumbi ngayo yale nguqulo intsha, unokujonga iinkcukacha Kule khonkco ilandelayo.
