Momwe ndidakhalira wokamba Percona Live (ndi zina zochititsa chidwi kuchokera kumalire aku America)

Percona Live Open Source Database Conference ndi chimodzi mwazochitika zazikulu pa kalendala ya dziko la DBMS. Nthawi ina zonse zidayamba ndikukula kwa imodzi mwamafoloko a MySQL, koma kenako idaposa kholo lake. Ndipo ngakhale zida zambiri (ndi alendo) zimagwirizanabe kwambiri ndi mutu wa MySQL, chidziwitso chambiri chakhala chokulirapo: izi zikuphatikiza MongoDB, PostgreSQL, ndi ma DBMS ena osadziwika. Chaka chino "Perkona" idakhala chochitika chofunikira pa kalendala yathu: kwa nthawi yoyamba tidatenga nawo gawo pamsonkhano waku America. Monga mukudziwa kale, Ndife okhudzidwa kwambiri ndi momwe matekinoloje owunikira akuyendera masiku ano. Ndi kusintha kwa ma paradigms a zomangamanga kupita ku kusinthasintha kwakukulu, ma microservices ndi mayankho amagulu, zida zomwe zikutsatiridwa ndi njira zothandizira ziyeneranso kusintha. Izi, kwenikweni, ndi zomwe lipoti langa linali. Koma choyamba, ndikufuna ndikuuzeni momwe anthu amafikira kumisonkhano yaku US komanso zodabwitsa zomwe angayembekezere ndege ikangofika.

Ndiye anthu amapita bwanji kumisonkhano yakunja? M'malo mwake, izi sizovuta kwambiri: muyenera kulumikizana ndi komiti ya pulogalamuyo, lengezani mutu wanu wa lipotilo, ndikuphatikiza umboni kuti mumadziwa kale kuyankhula pazochitika zaukadaulo. Mwachibadwa, chifukwa cha malo a msonkhanowo, luso la chinenero ndilofunika kwambiri. Kudziwa kuyankhula pamaso pa olankhula Chingerezi ndikofunikira kwambiri. Nkhani zonsezi zimakambidwa ndi komiti ya pulogalamuyo, amawunika zomwe mungathe, ndipo mwina / kapena.

Nkhani zamalamulo, ndithudi, ziyenera kuthetsedwa paokha. Chifukwa chazifukwa zomwe mumamvetsetsa, kupeza zikalata za visa ku Russia kumakhala kovuta. Mwachitsanzo, ku Moscow kudikirira Visa ya Mlendo panthawi yolemba ndi masiku 300. Anthu okhala m’mizinda ikuluikulu, nthaŵi zambiri, amazoloŵera kulambalala mavuto ameneŵa mwa kukonza zikalata m’maiko ena oyandikana nawo. Koma popeza timakhala ku Irkutsk, dziko lathu lapafupi kwambiri ndi Mongolia ... Imani. Ulaanbaatar! Kupatula apo, palinso kazembe waku America komweko. Ndipo, kunena zoona, sizodziwika makamaka ndipo chifukwa chake sizotanganidwa kwambiri. Ulendo wochokera ku Irkutsk kupita ku Ulaanbaatar pa ndege umatenga ola limodzi. Nthawi yanthawi sikusintha - mutha kupitiliza kugwira ntchito momasuka komanso mozolowera. Zimatenga theka la ola kuchokera ku ambassy mpaka kulandira visa. Chovuta chokha ndichakuti mutha kulipira chindapusa chokhacho ndi ndalama mu tugriks kunthambi ya Khaan Bank. Chifukwa chake, ngati mukufuna kubwera nthawi yomweyo kuti mudzatenge visa yokonzekera, ndiye kuti zingakhale bwino kukhala ndi munthu yemwe mumamudziwa yemwe angathandize kuthetsa vutoli.

Choncho. Visa yalandilidwa, mpando wa ndege wamangidwa. Kulowa ku States komweko kukuyandikira. Kuwoloka malire kumeneko nthawi zonse kwakhala ntchito yotopetsa kwambiri. Nditafika koyamba mu 2010, ndinadabwa kwambiri ndi nthawi yayitali yoyendetsa pasipoti ku Washington. Ayi, ndithudi, mzere wopita ku mazenera omwe amasilira wakhala wamakono. Koma kwa nthawi ndithu (zaka zingapo kuti zikhale zenizeni) iwo awonjezera makina apadera omwe amajambula zambiri zanu ndikukupatsani pepala ndi chithunzi chanu - ndipo chirichonse chakhala chofulumira. Pamaulendo anga onse aposachedwapa, ndinafika ndi tikiti yopita ndi kubwerera, ndi tsatanetsatane wa malo ogona, ndi zina zotero. Koma nthawi ino ndinafika ndi tikiti kumeneko yokhala ndi tsiku lokonzedwanso komanso popanda tikiti yobwerera yogwirizana nayo. Ndipo voila: chithunzi pa pepala loyera chinawoloka.

Njira ya Officer

Mzerewu unali mwadzidzidzi monga momwe zinalili zaka zingapo zapitazo, ndipo pamene ndinafika ku ulamuliro wa pasipoti patapita ola limodzi, ndinafika womasuka kwathunthu. Msilikaliyo anafunsa chifukwa chimene ndadzera; Ndinayankha - bizinesi (malonda, mtundu wa visa b1 / b2 amalola izi) ndi kupuma (tchuthi), komwe adalongosola ndege yomwe ndinafika ndikulongosola kuti sindinali m'nkhokwe za omwe akuuluka. Ndinkafuna kwambiri kugona ndipo ndinayankha kuti sindikudziwa chifukwa chake izi zili choncho ... mwinamwake chifukwa ndinasintha masiku onyamuka. Mkulu wa ku America anachita chidwi ndi chifukwa chomwe ndinasinthira masiku anga othawa komanso nthawi yomwe ndimabwerera. Kumene ndinayankha kuti ndinasintha chifukwa ndinaganiza zowuluka nthawi ina, ndipo ndikabwerera, ndimatha kupereka yankho lofanana. Ndiyeno mkuluyo anati “chabwino,” anakweza dzanja lake n’kuitana mnyamata wina, amene anandipatsa pasipoti yanga. Ananditengera cheke chowonjezera. Pondikumbutsa kuti ndinali ndi ndege mu ola limodzi, iye anayankha modekha kuti “osadandaula, mwachedwa ndithu, zitenga maola angapo, akupatsani mapepala oti musamutsire matikiti.”

O-o-kay. Ndinalowa m'chipindamo: panali anthu ena pafupifupi 40 atakhala pamenepo, panali 3 kuchokera kuthawa kwathu, kuphatikizapo ine. Ndinakhala pansi ndikungoyang'ana mufoni yanga, pamene mlonda adathamanga nthawi yomweyo ndikundiuza kuti ndizimitse ndikuloza makoma: zidapezeka kuti pali zizindikiro zozungulira kuti "simungagwiritse ntchito mafoni," Sindinazindikire chifukwa cha kutopa komanso kusowa tulo. Ndinazimitsa, koma mnansi wanga analibe nthawi - omwe alibe nthawi, mafoni awo amachotsedwa. Pafupifupi maola atatu ankadutsa, nthawi ndi nthawi munthu wina ankaitanidwa kuti athandizidwe. kuyankhulana, pamapeto pake sanandiyimbire kulikonse - adangondipatsa pasipoti yokhala ndi sitampu yomwe adandilowetsa. Chinali chiyani icho? (c) Zowona, tikiti yaulendo wophonya, pamapeto pake, idasinthidwa kutengera satifiketi yomwe idalandilidwa.

Mzinda wa Austin, Texas

Ndipo tsopano nthaka yaku Texas potsiriza ili pansi pa mapazi anga. Texas, ngakhale ndi dzina lodziwika bwino kwa anthu aku Russia, akadali simalo omwe anthu ammudzi amayendera. Ndinapitako ku California ndi ku New York kukagwira ntchito, koma sindinapite kummwera kwenikweniko. Ndipo zikadapanda Percona Live, sizikudziwikabe kuti tikanayenera kutero.

Mzinda wa Austin ndi "California enclave" mkati mwa boma la Texas. Kodi zimenezi zinachitika bwanji? Maziko oyambirira a kukula mofulumira kwa Chigwa, kuwonjezera pa, ndithudi, ndalama za boma, zinali nyengo yofatsa ndi mtengo wotsika wa moyo ndi kuchita malonda. Koma tsopano popeza San Francisco ndi madera ozungulira akhala chizindikiro cha mtengo wokwera kwambiri, oyambitsa atsopano akufunafuna malo atsopano. Ndipo Texas idakhala njira yabwino. Choyamba, zero msonkho. Kachiwiri, msonkho wa zero pa phindu lalikulu kwa mabizinesi payekha. Chiwerengero chachikulu cha mayunivesite chimatanthawuza msika wotukuka wa ogwira ntchito oyenerera. Mtengo wa moyo siwokwera kwambiri malinga ndi miyezo yaku America. Zonsezi zimapereka mafuta abwino opangira mabizinesi atsopano aukadaulo. Ndipo - amapanga omvera pazochitika zoyenera.

Percona Live yokha idachitika ku Hayatt Regency Hotel. Malinga ndi dongosolo lomwe tsopano likudziwika, msonkhanowu unali ndi mitsinje ingapo yofanana: iwiri pa MySQL, imodzi pa Mongo ndi PostgreSQL, komanso magawo a AI, chitetezo ndi bizinesi. Tsoka ilo, sikunali kotheka kuwunika mokwanira pulogalamu yonse chifukwa cha ndandanda yotanganidwa yokonzekera ntchito yathu. Koma malipoti amene ndinali ndi mwayi wowaona anali osangalatsa kwambiri. Ndikadawonetsa makamaka "Mawonekedwe Osintha a Open Source Databases" lolemba Peter Zaitsev ndi "Deta Yambiri?" ndi Yves Trudeau. Tinakumana ndi Alexey Milovidov kumeneko - adaperekanso lipoti ndipo adabwera ndi gulu lonse la Clickhouse, lomwe ndinakhudzanso m'mawu anga.

Ndiloleni ndinene

Ndipo, kwenikweni, za chinthu chachikulu: ndimakamba chiyani? Lipotilo lidaperekedwa pa momwe tidasankhira njira yowunikira tokha patokha pamtundu watsopano. Mwanjira ina zidachitika ku Palestine kuti pakafunika chida chamtunduwu, ndi chizolowezi kutenga Clickhouse mwachisawawa. Chifukwa chiyani? "Chifukwa amathamanga." Ndi liwiro kwenikweni? Zingati? Kodi pali zabwino ndi zoyipa zina zomwe sitiziganizira mpaka titayesa zina? Tinaganiza zokhala ndi njira yolimba pophunzira nkhaniyi; koma kungotchula zinthu m'ndandanda n'kotopetsa, ndipo kunena zoona, n'kosaiwalika. Ndipo kwa anthu, monga wodabwitsayo akuphunzitsa p0b0chi Roman Poborchy, ndizosangalatsa kumva nkhani. Chifukwa chake, tidakambirana momwe tidathamangitsira ma DBMS onse oyesedwa pazomwe timapanga, zomwe timalandira munthawi yeniyeni sekondi iliyonse kuchokera kwa othandizira athu.

Kodi mudakhala ndi zowonera zotani pamwambowu?

Chilichonse chidakonzedwa mwangwiro, malipoti anali osangalatsa. Koma chomwe chidawoneka bwino kwambiri ndichakuti ma DBMS tsopano akulowera paukadaulo. Anthu ambiri, mwachitsanzo, sanagwiritse ntchito njira zodzipangira okha kwa nthawi yayitali. Sitinazolowere izi ndipo, motero, sitiwona zachilendo pakuyika, kukonza ndi kuthandizira DBMS. Ndipo kumeneko mitambo yakhala ngati akapolo kwa aliyense, ndipo RDS yokhazikika ndiye njira yosasinthika. Bwanji mukuda nkhawa ndi magwiridwe antchito, chitetezo, zosunga zobwezeretsera, kapena gwiritsani ntchito akatswiri apadera pa izi, ngati mutha kutenga ntchito yokonzekera, pomwe zonse zakonzedweratu kwa inu?

Izi ndizosangalatsa kwambiri ndipo, mwina, kudzuka kwa iwo omwe sanakonzekere kupereka mayankho awo mwanjira yotere.

Ndipo kawirikawiri, izi sizikugwira ntchito ku DBMS kokha, koma kuzinthu zonse za seva. Ulamuliro ukusintha kuchokera ku Linux console kupita pa intaneti, komwe muyenera kusankha mautumiki oyenera ndikuwoloka wina ndi mzake, kumvetsetsa momwe operekera mitambo amagwirira ntchito ndi EKS, ECS, GKE ndi zilembo zina zazikulu. M'dziko lathu, chifukwa cha malamulo omwe timakonda pazambiri zaumwini, osewera apakhomo pamsika wochititsa chidwi apanga bwino, koma mpaka pano takhala tikutsalira pang'ono kumbuyo kwa kayendetsedwe kaukadaulo wapadziko lonse lapansi, ndipo sitinakumanepo ndi kusintha koteroko tokha. .

Ndidzasindikiza kusanthula kwatsatanetsatane kwa lipotilo, koma mtsogolomo: likukonzedwa pano - ndikulimasulira kuchokera ku Chingerezi kupita ku Chirasha :)
