Engaba kanjani isikhulumi sePercona Live (neminye imininingwane ethokozisayo evela emngceleni waseMelika)

Percona Live Open Source Database Conference ingenye yezenzakalo eziyinhloko ekhalendeni lomhlaba le-DBMS. Kwake kwenzeka konke kwaqala ngokuthuthukiswa kwemfoloko eyodwa ye-MySQL, kodwa-ke yadlula kakhulu ukhokho wayo. Futhi nakuba izinto eziningi (kanye nezivakashi) zisahlobene eduze nesihloko se-MySQL, isizinda solwazi jikelele sesibe banzi kakhulu: lokhu kuhlanganisa i-MongoDB, i-PostgreSQL, namanye ama-DBMS angadumile. Kulo nyaka i-“Perkona” ibe umcimbi obalulekile ekhalendeni lethu: ngokokuqala ngqa ukubamba iqhaza kule ngqungquthela yaseMelika. Njengoba cishe uyazi kakade, Sikhathazeke kakhulu ngesimo sobuchwepheshe bokuqapha emhlabeni wanamuhla. Ngokushintsha kwemibono yengqalasizinda iye ekuguquguqukeni okuphezulu, ama-microservices kanye nezixazululo zeqoqo, amathuluzi ahambisanayo nezindlela zokweseka kumele nazo ziguquke. Lokho, empeleni, kwakuyilokho umbiko wami owawumayelana. Kodwa okokuqala, ngifuna ukukutshela ukuthi abantu ngokuvamile bafika kanjani ezingqungqutheleni zase-US nokuthi yiziphi izimanga abangazilindela ngokushesha ngemva kokufika kwendiza.

Pho abantu bangena kanjani ezingqungqutheleni zakwamanye amazwe? Eqinisweni, le nqubo ayinzima kangako: udinga ukuxhumana nekomidi lohlelo, umemezele isihloko sakho sombiko, futhi unamathisele ubufakazi bokuthi usuvele unolwazi lokukhuluma emicimbini yobuchwepheshe. Ngokwemvelo, uma kubhekwa indawo yengqungquthela, ulwazi lolimi luyiphuzu elibalulekile. Isipiliyoni sokukhuluma phambi kwezilaleli ezikhuluma isiNgisi sifiseleka kakhulu. Zonke lezi zinkinga kuxoxwa ngazo nekomidi lohlelo, lihlola amandla akho, futhi kungaba/noma.

Izinkinga zomthetho, kunjalo, kufanele zixazululwe ngokuzimela. Ngenxa yezizathu oziqondayo ngokwakho, ukuthola imibhalo ye-visa eRussia kunzima ngandlela thile. Isibonelo, eMoscow ukulinda iVisa Yezivakashi ngesikhathi sokubhala kuyizinsuku ezingama-300. Izakhamuzi zenhloko-dolobha, ngokuvamile, zijwayele ukweqa lobu bunzima ngokucubungula imibhalo kwezinye izifundazwe ezingomakhelwane. Kodwa njengoba sizinze e-Irkutsk, izwe elingumakhelwane wethu eliseduze yiMongolia... Yeka. Ulaanbaatar! Phela kukhona nenxusa laseMelika lapho. Futhi, uma ngikhuluma iqiniso, ayithandwa kakhulu futhi ngakho-ke ayimatasa kakhulu. Uhambo olusuka e-Irkutsk luya e-Ulaanbaatar ngendiza luthatha ihora elilodwa. Indawo yesikhathi ayishintshi - ungaqhubeka nokusebenza ngesivinini esikhululekile nesijwayelekile. Kuthatha isigamu sehora ngempela kusukela ekungeneni kwenxusa kuya ekutholeni i-visa. Ubunzima kuphela ukuthi ungakhokha kuphela imali ye-consular ngokheshi e-Tugriks egatsheni lase-Khaan Bank. Ngakho-ke, uma ufuna ukuza ngokushesha ukuze uthole i-visa esenziwe ngomumo, kungaba kuhle ukuba nomuntu omaziyo lapho ongasiza ekuxazululeni lolu daba.

Ngakho. I-visa yamukelwe, isihlalo endizeni siboshiwe. Ukungena e-States ngokwako kuyasondela. Ukuwela umngcele bekulokhu kuwumsebenzi okhathazayo kakhulu. Lapho ngifika okokuqala ngo-2010, ngashaqeka ukuthi kwathatha isikhathi esingakanani ukulawulwa kwamapasi eWashington. Cha, kunjalo, ulayini oya kumafasitela afiselekayo ubulokhu ungowokudala. Kodwa isikhathi eside manje (iminyaka eminingana ukuze ibe ncamashi) bengeze imishini ekhethekile ethwebula imininingwane yakho futhi ikunikeze ipheshana elinesithombe sakho - futhi konke sekushesha. Kulo lonke uhambo lwami lwakamuva, ngifike nethikithi lokuya nokubuya, nayo yonke imininingwane yendawo yokuhlala, njll. ithikithi. Kodwa kulokhu ngafika nethikithi lapho linedethi ehlelwe kabusha futhi lingenalo ithikithi lokubuya elihlobene nalo. Futhi voila: isithombe ephepheni elimhlophe sanqanyulwa.

Indlela yesikhulu

Ulayini waba ngokuzumayo njengoba wawunjalo eminyakeni embalwa edlule, futhi lapho ekugcineni ngifika ekulawuleni ipasipoti ngemva kwehora, ngafika ngikhululekile ngokuphelele. Iphoyisa labuza ukuthi ngize ngani; Ngaphendula - ibhizinisi (ukuthengisa, uhlobo lwe-visa b1/b2 luvumela lokhu) nokuphumula (iholide), lapho acacisa ukuthi iyiphi indiza engafika kuyo futhi yachaza ukuthi ngangingekho ku-database yalabo abahamba ngezindiza. Ngangifuna ngempela ukulala futhi ngaphendula ngokuthi angazi ukuthi kungani lokhu kunjalo... mhlawumbe ngoba ngishintshe izinsuku zokuhamba. Isikhulu saseMelika sasinentshisekelo yokuthi kungani ngishintshe izinsuku zami zendiza nokuthi ngibuya nini ngendiza. Engaphendula ngakho ukuthi ngishintshile ngoba nginqume ukundiza ngesikhathi esihlukile, futhi lapho ngindiza ngibuya, nginganikeza impendulo elinganiselwe. Khona-ke isikhulu sathi “kulungile,” saphakamisa isandla sabiza enye insizwa, eyamnika ipasipoti yami. Wangiyisa ngesheke elengeziwe. Ukuze ngikhumbuze ukuthi nganginendiza ngemva kwehora, waphendula ngomoya ophansi wathi “ungakhathazeki, ushiywe yisikhathi nakanjani, kuzothatha amahora ambalwa, bazokunikeza iphepha lokudlulisa amathikithi.”

O-o-kay. Ngangena ekamelweni: kwakunabanye abantu abangaba ngu-40 ababehlezi lapho, kwakukhona 3 abavela endizeni yethu, kuhlanganise nami. Ngahlala phansi ngabuka ocingweni lwami, kwaqhamuka unogada wagijima ngokushesha wathi angilucime wakhomba izindonga: kwavela ukuthi kunezimpawu ezithi “awukwazi ukusebenzisa amafoni,” nokusho ukuthi. Angizange nginake ngenxa yokukhathala nokungalali. Ngayicisha, kodwa umakhelwane wami wayengenaso isikhathi - labo abangenaso isikhathi, izingcingo zabo zithathwa nje. Kwadlula cishe amahora amathathu, ngezikhathi ezithile kwakubizwa othile ukuze athole usizo olwengeziwe. inhlolokhono, ekugcineni abangibizanga ndawo - bavele banginika ipasipoti enesigxivizo bangingenisa. Kwakuyini? (c) Yiqiniso, ithikithi lendiza ephuthelwe, ekugcineni, empeleni, lashintshwa ngokusekelwe kusitifiketi esitholiwe.

Idolobha lase-Austin, eTexas

Futhi manje inhlabathi yaseTexas ekugcineni ingaphansi kwezinyawo zami. I-Texas, nakuba i-toponym evamile kubantu baseRussia, namanje akuyona indawo evakashelwa kakhulu ngabantu bakithi. Ngike ngaya eCalifornia naseNew York ngaphambi komsebenzi, kodwa angikaze ngiye eningizimu kangako. Futhi ukube bekungeyona i-Percona Live, namanje akwaziwa ukuthi bekufanele senze nini.

Idolobha lase-Austin liyinto "ye-California enclave" ngaphakathi kwesifunda saseTexas. Kwenzeka kanjani lokhu? Isisekelo sokuqala sokukhula ngokushesha kweSigodi, ngaphezu kwalokho, vele, ukutshalwa kwezimali kukahulumeni, kwakuyisimo sezulu esipholile kanye nezindleko eziphansi zokuphila nokwenza ibhizinisi. Kodwa manje njengoba iSan Francisco kanye nezindawo ezizungezile seziwuphawu lwezindleko ezimba eqolo, amabhizinisi amasha afuna izindawo ezintsha. Futhi iTexas yaba inketho enhle. Okokuqala, intela engenayo iqanda. Okwesibili, intela enguziro yenzuzo enkulu yosomabhizinisi ngabanye. Inani elikhulu lamanyuvesi lisho imakethe ethuthukisiwe yabasebenzi abaqeqeshiwe. Izindleko zokuphila aziphezulu kakhulu ngokwezindinganiso zaseMelika. Konke lokhu ngokuvamile kunikeza uphethiloli omuhle wokuthuthukiswa kwamabhizinisi amasha ezobuchwepheshe. Futhi - idala izethameli zemicimbi efanele.

IPercona Live yona yenzeka eHayatt Regency Hotel. Ngokohlelo oseludumile manje, ingqungquthela ibiqukethe imifudlana ehlukene yezihloko ezifanayo: ezimbili ku-MySQL, eyodwa ngakunye ku-Mongo ne-PostgreSQL, kanye nezigaba ze-AI, ezokuphepha kanye nebhizinisi. Ngeshwa, akwenzekanga ukuhlola ngokugcwele lonke uhlelo ngenxa yesimiso esimatasa sokulungiselela ukusebenza kwethu. Kodwa imibiko engaba nethuba lokuyibheka yayijabulisa kakhulu. Ngingagqamisa ikakhulukazi "Indawo Eguqukayo Yemininingwane Egciniwe Yemithombo Evulekile" kaPeter Zaitsev kanye "Nedatha Eningi?" by Yves Trudeau. Sahlangana no-Alexey Milovidov lapho - wabuye wanikeza umbiko futhi weza neqembu lonke elivela ku-Clickhouse, engathinta futhi enkulumweni yami.

Ngivumele ngibike

Futhi, empeleni, mayelana nento esemqoka: bengikhuluma ngani? Umbiko wawugxile ekutheni sikhethe kanjani isistimu yokuqapha idatha yochungechunge lwesikhathi yethu yenguqulo entsha. Ngandlela-thile kwenzeka ePalestine yethu ukuthi lapho isidingo salolu hlobo lwethuluzi sivela, kuyisiko ukuthatha i-Clickhouse ngokuzenzakalelayo. Kungani? "Ngoba uyashesha." Ingabe ishesha ngempela? Malini? Ingabe kukhona okunye okuhle nokubi esingacabangi ngakho kuze kube yilapho sizama okunye? Sinqume ukuthatha indlela eqinile yokufunda lolu daba; kodwa ukumane ubhale izici kuyisicefe futhi, ngokungananaziyo, akukhumbuleki kakhulu. Futhi kubantu, njengoba omangalisayo efundisa p0b0rchy Roman Poborchy, kujabulisa kakhulu ukuzwa indaba. Ngakho-ke, sikhulume ngokuthi siqhube kanjani wonke ama-DBMS ahlolwe kudatha yethu yokukhiqiza, esiyithola ngesikhathi sangempela umzuzwana ngamunye kuma-ejenti ethu okuqapha.

Yimiphi imibono onayo ngomcimbi?

Konke kwakuhlelwe kahle, imibiko yayithakazelisa. Kodwa okwagqama kakhulu ukuthi ama-DBMS manje abheke kuphi kwezobuchwepheshe. Abantu abaningi, isibonelo, abazange basebenzise izixazululo zokuzisingatha isikhathi eside. Asikakujwayeli kakhulu lokhu futhi, ngokufanelekile, asiboni lutho olungajwayelekile ekufakeni, ekulungiseni nasekusekeleni i-DBMS. Futhi lapho amafu sekuyisikhathi eside egqilaza wonke umuntu, futhi i-RDS enemibandela iyindlela ezenzakalelayo. Kungani ukhathazeka ngokusebenza, ukuphepha, izipele, noma ukuqasha ochwepheshe abahlukene bezobuchwepheshe kulokhu, uma ungathatha isevisi eseyenziwe ngomumo, lapho yonke into isivele icatshangwe kusengaphambili?

Lokhu kuyathakazelisa kakhulu futhi, mhlawumbe, ukuvuka kwalabo abangakalungeli ukunikeza izixazululo zabo ngefomethi enjalo.

Futhi ngokuvamile, lokhu akusebenzi kuphela ku-DBMS, kodwa kuyo yonke ingqalasizinda yeseva. Ukuphatha kuyasuka kukhonsoli ye-Linux kuya kukhonsoli yewebhu, lapho udinga ukwazi ukukhetha izinsizakalo ezifanele futhi uwele komunye nomunye, uqonde ukuthi abahlinzeki bamafu abathile basebenza kanjani nge-EKS yabo, i-ECS, i-GKE nezinye izinhlamvu ezinkulu. Ezweni lethu, mayelana nomthetho wethu esiwuthandayo wedatha yomuntu siqu, abadlali basekhaya emakethe yokusingathwa bathuthuke kahle, kodwa kuze kube manje sisalele ngandlela thile ngemuva konqenqema oluhamba phambili lwenhlangano yezobuchwepheshe yomhlaba wonke, futhi asikakatholi izinguquko ezinjalo ze-paradigm. ngokwethu.

Ngizoshicilela ukuhlaziya okuningiliziwe kombiko, kodwa ngemva kwesikhashana: okwamanje uyalungiselelwa - ngiwuhumusha usuka esiNgisini ngiwuyise olimini lwesiRashiya :)
