2 mabhiriyoni ekutengeserana Chiyero chinoshanduka zuva nezuva - izvi mubhadharo, muripo, mafoni uye zvimwe zviitiko. 200 TB yedata iri kushingaira kuchinja, chinja zvishoma zvishoma 8PB yedata, uye iyi haisi dura, asi rarama data mune imwe chete kubhadharisa. Scale by data center - 5 zviuru maseva pane 14 saiti.
Technology stack
Patakaronga mavakirwo uye takatanga kuunganidza sisitimu, takaunza kunze kwenyika inonakidza uye yepamusoro matekinoroji. Mhedzisiro yacho ndeye tekinoroji stack inozivikanwa kune chero Internet player uye makambani anoita yakakwirira-mutoro masisitimu.
Iyo stack yakafanana neyevamwe vatambi vakuru: Netflix, Twitter, Viber. Iyo ine zvikamu zvitanhatu, asi isu tinoda kupfupisa nekuibatanidza.
Kuchinjika kwakanaka, asi mumubatanidzwa mukuru hapana nzira isina kubatana.
Hatisi kuzoshandura Oracle imwechete kuTarantool. Muchokwadi chemakambani makuru, iyi iutopia, kana crusade ye5-10 makore ane mhedzisiro isina kujeka. Asi Cassandra neCouchbase zvinogona kutsiviwa neTarantool zviri nyore, uye ndizvo zvatiri kuvavarira.
Sei Tarantool?
Pane 4 nzira dzakareruka nei takasarudza iyi database.
Speed. Takaita bvunzo dzemutoro paMegaFon maindasitiri masisitimu. Tarantool yakakunda - yakaratidza kuita kwakanyanya.
Izvi hazvireve kuti mamwe masisitimu haaite zvinodiwa neMegaFon. Zvazvino zvigadziriso zvendangariro zvinogadzira zvekuti matura ekambani akawandisa. Asi isu tinofarira kubata nemutungamiri, uye kwete nemunhu ari kusarira kumashure, kusanganisira muyedzo yemutoro.
Tarantool inovhara zvinodiwa nekambani kunyangwe munguva refu.
mutengo weTCO. Tsigiro yeCouchbase paMegaFon mavhoriyamu inodhura mari yezvenyeredzi, asi neTarantool mamiriro acho akanyanya kufadza, uye akafanana mukushanda.
Chimwe chinhu chakanaka chakapesvedzera zvishoma sarudzo yedu ndechekuti Tarantool inoshanda zvirinani nendangariro pane mamwe dhatabhesi. Anoratidza zvakanyanya kushanda zvakanaka.
Kuvimbika. MegaFon inodyara mukuvimbika, pamwe kupfuura chero ani zvake. Saka patakatarisa Tarantool, takaona kuti taifanira kuita kuti ikwane zvatinoda.
Isu takadyara nguva yedu nemari, uye pamwe neMail.ru takagadzira vhezheni yebhizinesi, iyo yava kushandiswa mune mamwe makambani akati wandei.
Tarantool-bhizinesi rakatigutsa zvachose maererano nekuchengetedza, kuvimbika, uye kutema miti.
Kudyidzana
Chinhu chakakosha kwandiri ndechekuti kuonana zvakananga nemugadziri. Izvi ndizvo chaizvo zvakapihwa nevakomana veTarantool.
Kana iwe ukauya kune mutambi, kunyanya uyo anoshanda neanchor client, uye uchiti unoda dhatabhesi kuti ugone kuita izvi, izvi neizvi, anowanzopindura:
- Zvakanaka, isa zvinodikanwa pazasi pemurwi iwoyo - rimwe zuva, isu tichasvika kwavari.
Vazhinji vane mugwagwa wemakore 2-3 anotevera, uye hazvigoneke kubatanidza ipapo, asi vagadziri veTarantool vanobata nekuvhurika kwavo, uye kwete chete kubva kuMegaFon, uye kugadzirisa hurongwa hwavo kune mutengi. Zvakanaka uye tinozvida chaizvo.
Kwataishandisa Tarantool
Isu tinoshandisa Tarantool mune akati wandei zvinhu. Yokutanga iri mutyairi, iyo yatakagadzira pane kero dhairekitori system. Pane imwe nguva ndaida kuti ive hurongwa hwakafanana neYandex.Maps neGoogle Maps, asi zvakazoitika zvishoma zvakasiyana.
Semuenzaniso, iyo kero catalog mune yekutengesa interface. PaOracle, kutsvaga kero yaunoda kunotora masekonzi gumi nemaviri-12. - nhamba dzisina kugadzikana. Kana isu tichichinjira kuTarantool, tsiva Oracle neimwe dhatabhesi mukoni, uye toita kutsvaga kwakafanana, tinowana 13x yekumhanyisa! Guta rinobuda mushure metsamba yechitatu. Iye zvino tave kugadzirisa iyo interface kuti izvi zviitike mushure meyekutanga. Nekudaro, kumhanya kwekupindura kwakasiyana zvachose - milliseconds pachinzvimbo chemasekondi.
Yechipiri application idingindira rine fashoni rinonzi maviri-kumhanya IT. Izvi zvinodaro nekuti vanachipangamazano kubva kumakona ese vanoti makambani anofanirwa kuenda ikoko.
Kune dhizaini yezvivakwa, pamusoro payo pane madomasi, semuenzaniso, system yekubhadhara senge telecom, makambani masisitimu, kushuma kwemakambani. Uyu ndiwo musimboti usingade kubatwa. Ndiko kuti, hongu, zvinogoneka, asi paranoidly kuve nechokwadi chemhando, nekuti inounza mari kumubatanidzwa.
Inotevera inouya iyo layer ye microservices - chii chinosiyanisa mushandisi kana mumwe mutambi. Microservices inogona kukurumidza kugadzirwa zvichibva pane mamwe macache, ichiunza data kubva kune akasiyana madomasi ipapo. Here munda wekuedza - kana chimwe chinhu chisina kushanda, ndakavhara imwe microservice ndokuvhura imwe. Izvi zvinopa zvechokwadi yakawedzera nguva-ku-musika uye inowedzera kuvimbika uye nekukurumidza kwekambani.
Microservices pamwe ibasa guru reTarantool paMegaFon.
Kwatinoronga kushandisa Tarantool
Kana tikaenzanisa purojekiti yedu yekubhadhara yakabudirira nezvirongwa zveshanduko paDeutsche Telekom, Svyazcom, Vodafone India, zvine simba uye kugadzira zvinoshamisa. Mukuita kwekuita chirongwa ichi, kwete MegaFon chete uye chimiro chayo chakashandurwa, asiwo Tarantool-bhizinesi yakaonekwa paMail.ru, uye mutengesi wedu Nexign (aimbova Peter-Service) - BSS Bhokisi (bhokisi rekubhadhara mhinduro).
Ichi, neimwe nzira, chirongwa chenhoroondo yemusika weRussia. Inogona kuenzaniswa nezvinorondedzerwa mubhuku rinonzi βThe Mythical Man-Monthβ rakanyorwa naFrederick Brooks. Zvino, mumakore makumi matanhatu, IBM yakahaya vanhu zviuru zvishanu kuti vagadzire iyo itsva OS/60 yekushandisa system yema mainframes. Tine zvishoma - 360, asi edu ari mumavheti, uye tichifunga nezvekushandiswa kwevhu rakavhurika uye nzira itsva, tinoshanda zvakanyanya.
Pazasi pane madomasi ekubhadharisa kana, zvakanyanya kutaura, mabhizinesi masisitimu. Vanhu vanobva kumabhizinesi vanoziva CRM zvakanyanya. Wese munhu anofanira kunge aine mamwe masisitimu: Vhura API, API Gateway.
Vhura API
Ngatitarisei nhamba zvakare uye kuti Open API inoshanda sei parizvino. Mutoro wayo 10 kutengeserana pasekondi. Sezvo isu tichironga kushingaira kuvandudza iyo microservices layer uye kuvaka iyo MegaFon yeruzhinji API, isu tinotarisira kukura kukuru mune ramangwana muchikamu chino. Pachave paine 100 kutengeserana.
Handizivi kana tichikwanisa kuenzanisa neMail.ru muSSO - vakomana vanoita kunge vane 1 transactions pasekondi. Mhinduro yavo inonakidza kwazvo kwatiri uye isu tinoronga kutora ruzivo rwavo - semuenzaniso, kugadzira inoshanda SSO backup uchishandisa Tarantool. Iye zvino vanogadzira kubva kuMail.ru vari kutiitira izvi.
CRM
CRM ndiyo yakafanana 80 miriyoni vanyoreri vatinoda kuwedzera kusvika bhiriyoni, nekuti pane atova 300 miriyoni magwaro anosanganisira nhoroondo yemakore matatu. Tiri kutarisira chaizvo mabasa matsva uye pano nzvimbo yekukura yakabatana masevhisi. Iri ibhora richakura, nokuti pachava nemabasa akawanda uye akawanda. Saizvozvo, isu tichada nyaya; isu hatidi kugumburwa pane izvi.
Kuzvibhadharira pachezvayo maererano nekuburitsa invoice, kushanda nemaakaundi evatengi anotambirwa rakashandurwa kuita dunhu rakasiyana. Kuvandudza kushanda, applied domain architecture architectural pattern.
Iyo sisitimu yakakamurwa kuita domains, mutoro unogovaniswa uye kukanganisa kushivirira kunovimbiswa. Uyezve, takashanda nevakagoverwa zvivakwa.
Zvimwe zvese zvigadziriso zvemabhizinesi. Munzvimbo yekuchengetedza yekufona - 2 bhiriyoni pazuva, mabhiriyoni 60 pamwedzi. Dzimwe nguva unofanira kuzviverenga mumwedzi, uye zviri nani nokukurumidza. Kuongorora kwemari - izvi ndizvo chaizvo 300 mamiriyoni ari kuramba achikura nekukura: vanyoreri vanowanzomhanya pakati pevashandisi, vachiwedzera chikamu ichi.
Iyo yakanyanya telecom chikamu chenharembozha ndeye online billing. Aya ndiwo masisitimu anobvumidza iwe kufona kana kusafona, kuita sarudzo munguva chaiyo. Pano mutoro ndeye 30 transactions pasekondi, asi tichifunga nezvekukura kwekufambisa data, tinoronga. 250 kutengeserana, uye naizvozvo isu tinofarira zvikuru Tarantool.
Mufananidzo wapfuura ndiwo madomasi atiri kuzoshandisa Tarantool. CRM pachayo, hongu, yakakura uye isu tiri kuzoishandisa mupakati pachayo.
Yedu inofungidzirwa TTX nhamba ye100 miriyoni vanyoreri inondivhiringa semuvaki - ko kana 101 miriyoni? Iwe unofanirwa kudzokorora zvese zvakare? Kuti izvi zvisaitike, tinoshandisa cache, panguva imwechete tichiwedzera kuwanikwa.
Kazhinji, kune nzira mbiri dzekushandisa Tarantool. Chekutanga - kuvaka zvese cache paiyo microservice level. Sekunzwisisa kwandinoita, VimpelCom iri kutevera nzira iyi, ichigadzira cache yevatengi.
Isu hatisi kutsamira kune vatengesi, isu tiri kushandura iyo BSS musimboti, saka isu tine imwechete mutengi faira kunze kwebhokisi. Asi tinoda kuwedzera. Naizvozvo, isu tinotora nzira yakati siyanei - ita cache mukati mehurongwa.
Nenzira iyi kune kushomeka kuwiriranisa - imwe sisitimu ine basa kune ese ari maviri cache uye main master sosi.
Iyo nzira inoenderana zvakanaka neTarantool nzira ine transactional skeleton, apo chete zvikamu zvine chekuita nekuvandudzwa, ndiko kuti, shanduko yedata, inovandudzwa. Zvimwe zvese zvinogona kuchengetwa kumwewo. Iko hakuna hombe data dziva, isina kutarisirwa pasi rose cache. Cache dzakagadzirirwa sisitimu, kana zvigadzirwa, kana vatengi, kana kuita kuti hupenyu huve nyore pakugadzirisa. Kana munyoreri achifona uye akatsamwa nezve kunaka kwesevhisi yako, iwe unoda kupa sevhisi yemhando yepamusoro.
RTO uye RPO
Kune mazwi maviri muIT - OTR ΠΈ RPO.
Chinangwa chenguva yekudzorera ndiyo nguva inotora kudzorera sevhisi mushure mekutadza. RTO = 0 zvinoreva kuti kunyange kana chimwe chinhu chikakundikana, basa rinoramba richishanda.
Recovery point chinangwa - ino ndiyo nguva yekudzoreredza data, ingani data yatinogona kurasikirwa nayo pane imwe nguva yenguva. RPO = 0 zvinoreva kuti hatisi kurasikirwa nedata.
Tarantool basa
Ngatiedzei kugadzirisa dambudziko reTarantool.
Given: tswanda yemashandisirwo ayo munhu wese anonzwisisa, semuenzaniso, muAmazon kana kumwewo. Zvinoda kuitira kuti ngoro yekutenga ishande maawa makumi maviri nemana nemazuva manomwe pasvondo, kana 24% yenguva. Iwo maodha anouya kwatiri anofanirwa kuramba akarongeka, nekuti hatigone kubatidza kana kudzima kubatana kwemunyoreri - zvese zvinofanirwa kuenderana. Iko kunyoreswa kwekare kunobata inotevera, saka iyo data yakakosha - hapana chinofanira kushaikwa.
chisarudzo. Iwe unogona kuedza kuigadzirisa musoro-on uye kubvunza vanogadzira dhatabhesi, asi dambudziko harigone kugadziriswa nemasvomhu. Iwe unogona kuyeuka theorems, mitemo yekuchengetedza, quantum fizikisi, asi nei - haigone kugadziriswa padanho reDB.
Iyo yakanaka yekare yekuvaka maitiro inoshanda pano - iwe unofanirwa kuziva nzvimbo yezvidzidzo zvakanaka uye woishandisa kugadzirisa iyi puzzle.
Mhinduro yedu: kugadzira registry yakagoverwa yezvikumbiro paTarantool - geo-yakagoverwa cluster. Mumufananidzo, aya matatu akasiyana ekugadzirisa data nzvimbo - mbiri pamberi peUrals, imwe mhiri kweUrals, uye tinogovera zvikumbiro zvese pakati penzvimbo idzi.
Netflix, iyo yave kunzi semumwe wevatungamiriri muIT, yaingova nedata imwe chete kusvika 2012. Manheru eKisimusi yeKatorike, Zvita 24, iyi data data yakadzika. Vashandisi muCanada neUSA vakasiiwa vasina mafirimu avanofarira, vakagumbuka uye vakanyora nezvazvo pasocial network. Netflix ikozvino ine nzvimbo nhatu dzedata pamhenderekedzo yekumadokero-kumabvazuva uye imwe kumadokero kweEurope.
Isu tiri kutanga kuvaka geo-yakagoverwa mhinduro - kukanganisa kushivirira kwakakosha kwatiri.
Saka isu tine cluster, asi zvakadini neRPO = 0 uye RTO = 0? Mhinduro yacho iri nyore, zvichienderana nehurukuro.
Chii chakakosha mumashandisirwo? Zvikamu zviviri: Kukanda Basket TO kuita sarudzo yekutenga, uye PASHURE. Iyo DO chikamu mune telecom inowanzonzi kurayira kubata kana rayira kutaurirana. Mune telecom, izvi zvinogona kuoma zvakanyanya kupfuura muchitoro chendaneti, nekuti ipapo mutengi anofanira kushumirwa, akapihwa mashanu sarudzo, uye izvi zvese zvinoitika kwenguva yakati, asi tswanda yakazadzwa. Panguva ino, kukundikana kunogoneka, asi hazvityisi, nekuti zvinoitika zvinopindirana pasi pekutariswa kwevanhu.
Kana iyo Moscow data data kamwe-kamwe ikakundikana, zvino nekushandura otomatiki kune imwe data data, isu ticharamba tichishanda. Nechepfungwa, chimwe chigadzirwa chinogona kurasika mungoro, asi unozviona, wedzera kungoro zvakare uye ramba uchishanda. Muchiitiko ichi, RTO = 0.
Panguva imwecheteyo, pane chechipiri sarudzo: patakadzvanya "submit", tinoda kuti data irege kurasika. Kubva panguva ino zvichienda mberi, otomatiki inotanga kushanda - iyi iRPO = 0. Uchishandisa aya maviri akasiyana mapatani, mune imwe nyaya inogona kungova geo-yakagoverwa cluster ine imwe switchable master, mune imwe nyaya imwe mhando yequorum rekodhi. Maitiro anogona kusiyana, asi isu tinogadzirisa dambudziko.
Kupfuurirazve, kuve neregistry yakagoverwa yezvikumbiro, isu tinogona zvakare kuyera zvese - kuva nevazhinji vanotumira uye vaurayi vanowana iyi registry.
Cassandra uye Tarantool pamwe chete
Pane imwe nyaya - "showcase of balances". Heino nyaya inonakidza yekubatana kwekushandiswa kweCassandra neTarantool.
Isu tinoshandisa Cassandra nekuti 2 bhiriyoni mafoni pazuva haisi iyo inogumira, uye pachave nezvimwe. Vatengesi vanofarira kuisa mavara traffic kubva kune sosi; zvakawanda uye zvakawanda zvakawanda zviri kuoneka pamasocial network, semuenzaniso. Zvose zvinowedzera nyaya.
Cassandra inobvumidza iwe kuyera yakatwasuka kune chero saizi.
Tinonzwa takasununguka neCassandra, asi ine dambudziko rimwe - haina kunaka pakuverenga. Zvese zvakanaka pakurekodha, 30 pasekondi haisi dambudziko - dambudziko rekuverenga.
Naizvozvo, nyaya ine cache yakaonekwa, uye panguva imwe chete isu takagadzirisa dambudziko rinotevera: pane yekare yechinyakare kesi apo michina kubva pakuchinja kubva pamhepo kubhadharisa ichipinda mumafaira atinoisa muCassandra. Isu takanetseka nedambudziko rekurodha kwakavimbika kwemafaira aya, kunyangwe tichishandisa zano reBMM maneja kufambisa faira - kune mhinduro dzinobata kufambisa kwefaira nemazvo, uchishandisa UDP protocol, semuenzaniso, pane TCP. Izvi zvakanaka, asi zvichiri maminetsi, uye isu hatisati tazvitakura zvese, anoshanda munzvimbo yekufona haakwanise kupindura mutengi kuti chii chakaitika pachiyero chake - isu tinofanirwa kumirira.
Kuti izvi zvisaitike, isu tinoshandisa parallel functional reserve. Patinotumira chiitiko kuburikidza neKafka kuTarantool, tichiverengerazve aggregates munguva chaiyo, semuenzaniso, nhasi, tinowana. mari dzemari, iyo inogona kutamisa zviyero chero kumhanya, semuenzaniso, 100 zviuru zvekutengesa pasekondi uye izvo zvakafanana 2 masekonzi.
Chinangwa ndechekuti mushure mekuita kufona, mukati memasekonzi maviri muakaundi yako yega pachave kwete chete yakashandurwa chiyero, asi ruzivo rwekuti nei yakachinja.
mhedziso
Iyi yaive mienzaniso yekushandisa Tarantool. Isu takada chaizvo kuvhurika kweMail.ru uye kuda kwavo kufunga nyaya dzakasiyana.
Zvakatooma kune vanopa mazano kubva kuBCG kana McKinsey, Accenture kana IBM kutishamisa nechimwe chinhu chitsva - zvizhinji zvezvavanopa, isu tinotoita, takaita, kana kuti tiri kuronga kuita. Ini ndinofunga kuti Tarantool ichatora nzvimbo yayo yakakodzera mune yedu tekinoroji stack uye ichatsiva akawanda aripo matekinoroji. Isu tiri muchikamu chinoshanda chekusimudzira chirongwa ichi.
Chirevo chaOleg naAndrey ndechimwe chezvakanakisa paTarantool Musangano gore rapfuura, uye musi waChikumi 17 Oleg Ivlev achataura pa nemushumo . Alexander Deulin achapawo mharidzo kubva kuMegaFon . Ngationei kuti chii chachinja, zvirongwa zvipi zvaitwa. Joinha - musangano ndewemahara, zvese zvaunofanirwa kuita ndezve ... Zvese uye purogiramu yemusangano yakaumbwa: nyaya itsva, ruzivo rutsva mukushandisa Tarantool, zvivakwa, bhizinesi, zvidzidzo uye microservices.
