sesinye seziganeko eziphambili kwikhalenda yehlabathi yeDBMS. Kwakhe kwaqala ngokuphuhliswa kwenye yeefolokhwe zeMySQL, kodwa emva koko yadlula kakhulu inzala yayo. Kwaye nangona izixhobo ezininzi (kunye neendwendwe) zisahambelana ngokusondeleyo nesihloko se-MySQL, imvelaphi yolwazi jikelele iye yaba banzi kakhulu: oku kubandakanya i-MongoDB, i-PostgreSQL, kunye nezinye ii-DBMS ezingaziwayo. Kulo nyaka "uPerkona" waba sisiganeko esibalulekileyo kwikhalenda yethu: okokuqala sithatha inxaxheba kule nkomfa yaseMelika. Njengoko sele uyazi, . Ngokutshintsha kweeparadigms zeziseko ezingundoqo ukuya ekuguquguqukeni okuphezulu, ii-microservices kunye nezisombululo zeqela, izixhobo ezikhaphayo kunye neendlela zokuxhasa kufuneka zitshintshe. Leyo, enyanisweni, yayimalunga nengxelo yam. Kodwa okokuqala, ndifuna ukukuxelela ukuba abantu bafika njani kwiinkomfa zase-US kwaye zeziphi izinto ezimangalisayo abanokuzilindela ngokukhawuleza emva kokufika kwenqwelomoya.
Ngoko abantu bafika njani kwiinkomfa zamazwe angaphandle? Ngapha koko, le nkqubo ayintsonkothanga kangako: kufuneka uqhagamshelane nekomiti yenkqubo, ubhengeze isihloko sakho sengxelo, kwaye uncamathisele ubungqina bokuba sele unamava okuthetha kwimisitho yobugcisa. Ngokwemvelo, kunikwe ijografi yenkomfa, ubuchule bolwimi yinto ebalulekileyo. Amava okuthetha phambi kwabaphulaphuli abathetha isiNgesi anqweneleka kakhulu. Yonke le miba ixoxwe kunye nekomiti yenkqubo, ivavanya amandla akho, kwaye mhlawumbi / okanye.
Imiba yomthetho, ngokuqinisekileyo, kufuneka isonjululwe ngokuzimeleyo. Ngenxa yezizathu oziqondayo ngokwakho, ukufumana amaxwebhu e-visa eRashiya kunzima. Ngokomzekelo, eMoscow ukulinda iVisa yeeNdwendwe ngexesha lokubhala ziintsuku ezingama-300. Abemi bamakomkhulu, ngokubanzi, baqhele ukubugqitha obu bunzima ngokucwangcisa amaxwebhu kumazwe athile angabamelwane. Kodwa ekubeni sihlala e-Irkutsk, indawo yethu engummelwane osondeleyo yiMongolia ... Yeka. Ulaanbaatar! Ngapha koko, kukho indawo yozakuzo yaseMelika apho. Kwaye, ukunyaniseka, ayithandwa kakhulu kwaye ngoko ayixakekanga kakhulu. Uhambo olusuka e-Irkutsk ukuya e-Ulaanbaatar ngenqwelo-moya luthatha iyure enye. Ummandla wexesha awutshintshi - ungaqhubeka nokusebenza ngesantya esikhululekile nesiqhelekileyo. Kuthatha isiqingatha seyure ngokwenene ukusuka ekungeneni kwi-ambassy ukuya ekufumaneni i-visa. Ekuphela kobunzima kukuba ungahlawula umrhumo we-consular kuphela ngemali ekhoyo eTugriks kwisebe leBhanki yaseKhaan. Ke ngoko, ukuba ufuna ukuza kwangoko ukuze ufumane i-visa esele yenziwe, kuya kuba kuhle ukuba nomntu omaziyo apho onokukunceda ukusombulula lo mba.
Ngoko. I-visa ifunyenwe, isihlalo kwinqwelomoya sifakwe isali. Ukungena e-States ngokwawo kusondela. Ukuwela umda bekusoloko kungumsebenzi odinisayo. Xa ndifika okokuqala kwi-2010, ndothuswa kukuba ulawulo lwepaspoti luthathe ixesha elide kangakanani eWashington. Hayi, ngokuqinisekileyo, umgca kwiifestile ezinqwenelekayo uhlala uyinto yakudala. Kodwa ixeshana ngoku (iminyaka eliqela ukuba ichane) bongeze oomatshini abakhethekileyo abaskena ulwazi lwakho kwaye bakunike iphetshana elinomfanekiso wakho - kwaye yonke into iye yakhawuleza. Kuzo zonke iihambo zam zamva nje, ndifike netikiti lokuya nokubuya, ndinazo zonke iinkcukacha zendawo yokuhlala, njl. njl. kwitikiti. Kodwa ngeli xesha ndafika ndinetikiti apho linomhla owenziwe ngokutsha kwaye lingenalo itikiti lokubuya elinxulumene nalo. Kwaye voila: ifoto ekwiphepha elimhlophe yacinywa.
Indlela yeGosa
Umgca ngokukhawuleza ude ude ube yiminyaka embalwa edlulileyo, kwaye xa ekugqibeleni ndenza ulawulo lwepaspoti emva kweyure, ndafika ndikhululekile ngokupheleleyo. Igosa labuza isizathu sokuba ndize; Ndaphendula - ishishini (ukuthengisa, uhlobo lwe-visa b1 / b2 luvumela oku) kunye nokuphumla (ikhefu), apho wacacisa ukuba yeyiphi indiza endifike kuyo kwaye ndachaza ukuba andikho kwi-database yezo zibhabhayo. Ndandifuna ngokwenene ukulala kwaye ndaphendula ukuba andiyazi ukuba kutheni oku kunjalo ... mhlawumbi ngenxa yokuba ndatshintsha imihla yokuhamba. Igosa laseMelika lalinomdla wokwazi ukuba kutheni nditshintshe imihla yam yenqwelomoya kunye nexesha endandibhabha ngalo ndibuya. Ndaphendula ndathi ndatshintsha kuba ndigqibe kwelokuba ndibhabhe ngexesha elahlukileyo, kwaye xa ndibuyela emva, ndinokunika impendulo eqikelelweyo kuphela. Kwaye ke igosa lathi βkulungile,β laphakamisa isandla laza labiza omnye umfana, elamnika ipasi lam. Undithathele isheke eyongezelelweyo. Ukundikhumbuza ukuba bendinenqwelo-moya kwisithuba esingangeyure, waphendula ngokuzolileyo wathi βungakhathazeki, ngokuqinisekileyo ulibele emva kwexesha kuyo, kuya kuthatha iiyure ezininzi, baya kukunika iphepha lokudlulisela amatikiti akho.β
O-o-kay. Ndiye ndangena eroomin: bekuhleli abanye abantu abamalunga ne 40, bebeyi 3 beflight yethu ndiquka nam. Ndahlala phantsi ndajonga nje umnxeba wam, xa unogada wabaleka ngoko nangoko wathi mandiyicime ekhomba ezindongeni: kwabonakala ukuba kukho imiqondiso ejikelezayo ethi βawukwazi ukusebenzisa imfonomfonoβ. Khange ndiqaphele ngenxa yokudinwa nokungalali. Ndiyicimile, kodwa ummelwane wam wayengenaxesha - abo bangenaxesha, iifowuni zabo zithathwa nje. Kwadlula malunga neeyure ezintathu, ngamaxesha athile umntu wayebizwa ukuze afumane uncedo olongezelelekileyo. udliwano-ndlebe, ekugqibeleni abazange bandibize naphina- bavele bandinika incwadana yokundwendwela enesitampu abandivumela ukuba ndingene. Yayiyintoni? (c) Liyinyaniso elokuba, itikiti lenqwelo-moya ephosiweyo, ekugqibeleni, litshintshiwe ngokwesiqinisekiso esifunyenweyo.
Isixeko saseAustin, eTexas
Kwaye ngoku umhlaba waseTexas ekugqibeleni uphantsi kweenyawo zam. I-Texas, nangona i-toponym eqhelekileyo kubantu baseRashiya, ayikabi yeyona ndawo ityelelwe kakhulu ngabantu basekhaya. Bendikhe ndaya eCarlifonia naseNew York ngaphambili ngenxa yomsebenzi, kodwa andizange ndiye emazantsi kangako. Kwaye ukuba bekungePercona Live, ayaziwa ukuba bekuya kufuneka nini.
Isixeko saseAustin siyinto "yeCalifornia enclave" ngaphakathi kwelizwe laseTexas. Yenzeka njani le nto? Isiseko sokuqala sokukhula ngokukhawuleza kweNtlambo, ukongeza, ngokuqinisekileyo, utyalo-mali lukarhulumente, yayiyimozulu epholileyo kunye neendleko eziphantsi zokuphila kunye nokwenza ishishini. Kodwa ngoku ekubeni iSan Francisco kunye neendawo eziyingqongileyo ziye zaba luphawu lweendleko ezixhomileyo, iziqalo ezintsha zikhangela iindawo ezintsha. Kwaye iTexas yajika yaba lukhetho oluhle. Okokuqala, zero irhafu yengeniso. Okwesibini, irhafu enguziro kwingeniso epheleleyo yoosomashishini ngabanye. Inani elikhulu leeyunivesithi lithetha imarike ephuhlisiweyo yabasebenzi abaqeqeshiweyo. Iindleko zokuphila aziphezulu kakhulu ngokwemigangatho yaseMelika. Konke oku kubonelela ngokubasa okulungileyo kuphuhliso lwamashishini amatsha obuchwepheshe. Kwaye - kudala abaphulaphuli kwiziganeko ezifanelekileyo.
IPercona Live ngokwayo yenzeka kwiHotele yaseHayatt Regency. Ngokweskimu esidumileyo ngoku, inkomfa ibiqulathe imijelo emininzi ehambelanayo: ezimbini kwiMySQL, enye nganye kwiMongo kunye nePostgreSQL, kunye namacandelo e-AI, ukhuseleko kunye neshishini. Ngelishwa, akuzange kwenzeke ukuyivavanya ngokupheleleyo inkqubo yonke ngenxa yeshedyuli exakekileyo yamalungiselelo okusebenza kwethu. Kodwa iingxelo endiye ndafumana ithuba lokuzijonga zaziyolisa kakhulu. Ndingathanda ukuqaqambisa ngakumbi "Ukutshintsha koMmandla woMthombo oVulekileyo" nguPeter Zaitsev kunye "neDatha eninzi kakhulu?" nguYves Trudeau. Sadibana no-Alexey Milovidov apho - naye wanika ingxelo waza weza naye lonke iqela elivela kwiClickhouse, endiyichukumisayo kwintetho yam.
Ndivumele ndixele
Kwaye, eneneni, malunga neyona nto iphambili: bendithetha ngantoni? Ingxelo yanikelwa kwindlela esikhethe ngayo inkqubo yokubeka iliso kuluhlu lwexesha ledatha yethu ukulungiselela inguqulelo entsha. Ngandlela-thile kwenzeka kwiiPalestina zethu ukuba xa imfuno yolu hlobo lwesixhobo ivela, kuyinto yesiko ukuthatha iClickhouse ngokungagqibekanga. Ngoba? "Ngenxa yokuba uyakhawuleza." Ngaba ikhawuleza ngokwenene? Kagakanani? Ngaba zikho ezinye izinto ezintle nezimbi esingazicingiyo de sizame enye into? Sagqiba ekubeni sithathe indlela enzima yokufunda lo mba; kodwa ukudwelisa nje iimpawu kuyadika kwaye, ngokuphandle, akulibaleki ncam. Nakubantu, njengoko lowo umangalisayo efundisa Roman Poborchy, kunomdla kakhulu ukuva ibali. Ke ngoko, sathetha malunga nendlela esiqhube ngayo zonke ii-DBMS ezivavanyiweyo kwidatha yethu yokuvelisa, esiyifumana ngexesha langempela rhoqo ngesibini kwiiarhente zethu zokubeka iliso.
Uthini umbono wakho kulo msitho?
Yonke into yayilungelelaniswe ngokugqibeleleyo, iingxelo zazinomdla. Kodwa eyona nto yayigqame kakhulu yayikukuba ii-DBMS ngoku zisingise khona ngokwetekhnoloji. Abantu abaninzi, umzekelo, abazange basebenzise izisombululo zokuzibamba ixesha elide. Asikayiqhelanga kakhulu le nto kwaye, ngokufanelekileyo, asiboni nto ingaqhelekanga ekufakeni ngesandla, ukuqwalasela kunye nokuxhasa i-DBMS. Kwaye apho amafu kudala ekhobokisa wonke umntu, kwaye i-RDS enemeko lukhetho olungagqibekanga. Kutheni ukhathazeka malunga nokusebenza, ukhuseleko, i-backups, okanye uqeshe iingcali zobugcisa ezahlukileyo kule nto, ukuba unokuthatha inkonzo esele yenziwe, apho yonke into sele icingelwe kuwe kwangaphambili?
Oku kunomdla kakhulu kwaye, mhlawumbi, ukuvusa umnxeba kwabo bangekakulungeli ukunika izisombululo zabo kwifomathi enjalo.
Kwaye ngokubanzi, oku akusebenzi kuphela kwi-DBMS, kodwa kuyo yonke isiseko seseva. Ulawulo lusuka kwi-console ye-Linux ukuya kwikhonsoli yewebhu, apho kufuneka ukwazi ukukhetha iinkonzo ezifanelekileyo kwaye uwele omnye nomnye, uqonde ukuba ababoneleli befu abathile basebenza njani kunye ne-EKS yabo, i-ECS, i-GKE kunye nezinye iileta ezinkulu. Kwilizwe lethu, ngokunxulumene nomthetho wethu esiwuthandayo kwidatha yomntu, abadlali basekhaya kwimakethi yokubamba baphuhlise kakuhle, kodwa ukuza kuthi ga ngoku sisalele ngasemva komda ophambili wentshukumo yetekhnoloji yehlabathi, kwaye okwangoku asikafumani tshintsho lweparadigm. ngokwethu.
Ngokuqinisekileyo ndiza kupapasha uhlalutyo oluneenkcukacha lwengxelo, kodwa emva kwexesha elifutshane: ngoku iyalungiswa - ndiyiguqulela ukusuka kwisiNgesi ukuya kwisiRashiya :)
