Shan sano ka hor waxaan isku dayay inaan la shaqeeyo Tarantool, laakiin markaa way ii shaqeyn weyday. Laakiin dhawaan waxaan qabtay webinar halkaas oo aan uga hadlay Hadoop, oo ku saabsan sida MapReduce u shaqeyso. Halkaa waxaa laygu waydiiyay su'aasha - "Maxaan Tarantool ugu isticmaalin hawshan?".
Xiisaha awgeed, waxaan go'aansaday inaan ku laabto, tijaabiyo nuqulkii ugu dambeeyay - iyo markan waxaan aad u jeclaa mashruuca. Hadda waxaan ku tusi doonaa sida loo qoro codsi fudud Tarantool, ku shub oo hubi waxqabadka, waxaadna arki doontaa sida ugu fudud oo wax walba u qaboojinayaan.
Waa maxay Tarantool
Tarantool waxay isu dhigtaa xog-ururin aad u degdeg badan. Waxaad halkaas gelin kartaa xog kasta oo aad rabto. Intaa waxaa dheer, ku celceli iyaga, shard - taas oo ah, kala qaybinta xog aad u tiro badan dhowr server oo isku dar natiijooyinka iyaga - samee xiriiriyaha-master-ga khalad-dulqaadka.
Marka labaad, waa server-ka codsiga. Waxaad ku qori kartaa codsiyadaada, ku shaqayn kartaa xogta, tusaale ahaan, tirtirto qoraaladii hore ee gadaasha iyadoo la raacayo sharciyo gaar ah. Waxaad si toos ah ugu qori kartaa server-ka Http ee Tarantula kaas oo ku shaqayn doona xogta: bixi nambarkooda, ku qor xog cusub halkaas oo dhammaan u yaree Master.
Waxaan akhriyay maqaal ku saabsan sida ay nimanku u sameeyeen saf fariin ah oo 300 ah, kuwaas oo ilmaynaya oo garaacaya - waxay leeyihiin waxqabadka ugu yar ee 20 farriimaha ilbiriqsi kasta. Halkan waxa aad si dhab ah u rogi kartaa oo ku qori kartaa codsi aad u weyn, kuwaasna lama kaydin doono, sida PostgreS.
Ku dhawaad server noocan oo kale ah, kaliya fudud, waxaan isku dayi doonaa inaan ku qeexo maqaalkan.
Ku rakibida
Imtixaanka, waxaan bilaabay saddex mashiinno dalwadeed oo caadi ah - 20 gigabyte hard drive ah, Ubuntu 18.04. 2 Virtual CPU iyo 4 gigabytes oo xusuusta ah.
Waxaan rakibnay Tarantool - waxaan wadnaa qoraal bash ah ama ku darnaa meel kayd ah oo aad ku habboonaato rakib Tarantool. Isku xirka qoraalka - (curl -L | VER=2.4 sudo -E bash). Waxaan leenahay amarro sida:
tarantoolctl waa taliska ugu weyn ee maaraynta xaaladaha Tarantula.
/etc/tarantool - halkan waxaa yaal qaabeynta oo dhan.
var/log/tarantool - Halkan waa geedo.
var/lib/tarantool - Halkan waxaa ku yaal xogta, ka dibna waxay u qaybsan yihiin tusaaleyaal.
Waxaa jira faylal tusaale ahaan la heli karo iyo tusaale-awood u leh - waxay ka kooban tahay waxa la bilaabi doono - faylka qaabeynta tusaalaha leh lua code, kaas oo qeexaya dekedaha uu dhageysto, xusuusta uu heli karo, Settings engine Vinyl, code ka shaqeeya bilowga. server-yada, shaandheynta, safafka, tirtirka xogta duugowday, iyo wixii la mid ah.
Tusaalooyinka waxay u shaqeeyaan sida PostgreS. Tusaale ahaan, waxaad doonaysaa inaad socodsiiso koobiyo badan oo kayd xogeed ah oo ku dheggan dekedo kala duwan. Waxaa soo baxday in dhowr tusaale oo database ah lagu bilaabay hal server, kuwaas oo ku dheggan dekedo kala duwan. Waxay yeelan karaan goobo gebi ahaanba kala duwan - hal tusaale ayaa hirgeliya hal macquul, ka labaad - mid kale.
Maareynta Tusaale
Waxaan haynaa amarka tarantoolctl kaas oo noo ogolaanaya inaan maamulno tusaalooyinka Tarantula. Tusaale ahaan, tusaale ahaan tarantoolctl jeeg ayaa hubin doona faylka qaabaynta oo odhan doona feylku waa sax haddii aanay jirin khaladaad syntax.
Waxaad arki kartaa heerka tusaale ahaan - tarantoolctl status example. Si la mid ah, waad bilaabi kartaa, joojin kartaa, dib u bilaabi kartaa.
Mar haddii tusaale uu socdo, waxaa jira laba siyaabood oo lagu xidhi karo.
1. Console maamulka
Sida caadiga ah, Tarantool waxay furtaa godad waxayna soo dirtaa qoraal cad oo ASCII ah si ay u maamusho Tarantula. Ku xidhidhiyaha konsole had iyo jeer waxa uu hoos yimaadaa isticmaalaha maamulka, ma jiro wax xaqiijin ah, markaa uma baahnid in aad ka soo saartid dekedda konsole si aad u xakamayso Tarantula dibadda.
Si aad sidan ugu xirto, waxaad u baahan tahay inaad geliso Tarantoolctl geli magaca tusaale. Amarka ayaa bilaabi doona console-ka oo ku xidhi doona isticmaaleha maamulka. Weligaa ha u soo bandhigin dekedda konsole dibadda - waxa fiican inaad uga tagto godad unug ahaan. Markaas kaliya kuwa wax qori kara godka ayaa awoodi doona inay ku xidhmaan Tarantula.
Habkan ayaa looga baahan yahay arrimaha maamulka. Si aad ula shaqeyso xogta, isticmaal habka labaad - nidaamka binary.
2. Isticmaalka borotokoolka binary si aad ugu xirto deked gaar ah
Habaynta waxaa ku jira dardaaran dhegeysi, kaas oo u furaya dekedda isgaarsiinta dibadda. Dekaddan waxa lagu isticmaalay borotokoolka binary oo xaqiijinta halkaas ayaa laga oggolaaday.
Xidhiidhkan, tarantoolctl ku xidh lambarka dekedda ayaa la isticmaalaa. Isticmaalka, waxaad ku xidhi kartaa server-yada fog, isticmaal xaqiijinta oo aad siin kartaa xuquuqo kala duwan oo gelitaan ah.
Duubista Xogta iyo Sanduuqa Module
Maadaama Tarantool ay tahay xog ururin iyo adeeg adeeg, waxay leedahay qaybo kala duwan. Waxaan xiiseyneynaa moduleka sanduuqa - waxay fulisaa shaqada xogta. Markaad wax ku qorto sanduuq, Tarantool waxay ku qortaa xogta diskka, waxay ku kaydisaa xusuusta, ama wax kale ku qabtaa.
Diiwaan geli
Tusaale ahaan, waxaan galeynaa sanduuqa sanduuqa oo wac sanduuqa.one function. Waxay ku qasbi doontaa Tarantool inuu socodsiiyo koodkayaga marka server-ka la bilaabay. Waxaan abuurnaa meel xogtayada lagu kaydin doono.
local function bootstrap()
local space = box.schema.create_space('example')
space:create_index('primary')
box.schema.user.grant('guest', 'read,write,execute', 'universe')
-- Keep things safe by default
-- box.schema.user.create('example', { password = 'secret' })
-- box.schema.user.grant('example', 'replication')
-- box.schema.user.grant('example', 'read,write,execute', 'space', 'example')
endTaas ka dib, waxaan abuurnaa index aasaasiga ah - aasaasiga ah - kaas oo aan ku raadin karno xogta. Sida caadiga ah, haddii aan la cayimin halbeegyada, goobta ugu horreysa ee gelista kasta ee tusmada asaasiga ah ayaa la isticmaali doonaa.
Ka dib waxaan u sameynaa deeq isticmaalayaasha martida, kaas oo aan ku xirno nidaamka binary. Waxaan ogolaneynaa akhrinta, qorista iyo fulinta guud ahaan tusaale ahaan.
Marka la barbardhigo xog-ururinta caadiga ah, wax walba halkan aad ayey ugu fudud yihiin. Waxaan haysanaa boos - aag xogtayada si fudud loo kaydiyo. Geli kasta waxaa loo yaqaan tuple. Waxay ku jirtaa MessagePack. Kani waa qaab aad u fiican - waa binary oo qaadata boos yar - 18 bytes iyo 27.
Way ku habboon tahay in lala shaqeeyo. Ku dhawaad khad kasta, xog kasta oo gelisa waxay yeelan kartaa tiirar gebi ahaanba kala duwan.
Waxaan ku eegi karnaa dhammaan meelaha bannaan anagoo adeegsanayna amarka Box.space. Si loo doorto tusaale gaar ah, waxaanu ku qornaa tusaale box.space oo aanu ka helnaa macluumaad buuxa.
Waxaa jira laba nooc oo matoorada ah oo lagu dhisay Tarantool: Xusuusta iyo Vinyl. Xusuustu waxay ku kaydisaa dhammaan xogta xusuusta. Sidaa darteed, wax waliba si fudud oo degdeg ah ayay u shaqeeyaan. Xogta waxaa lagu daadiyaa saxanka, sidoo kale waxaa jira hab qoraal ah oo horay loo qoray, markaa waxba lumin mayno haddii server-ku burburo.
Vinyl wuxuu ku kaydiyaa xogta diskka qaab aad loo yaqaan - taas oo ah, waxaad ku kaydin kartaa xog ka badan inta aan haysanno xusuusta, Tarantulana waxay ka akhrin doontaa diskka.
Hadda waxaan isticmaali doonaa Memory.

Tilmaanta aasaasiga ah waa in loo sameeyaa meel kasta, sababtoo ah waxba ma shaqeyn doono la'aanteed. Sida database kasta, waxaan abuurnaa goobta ugu horeysa - aqoonsiga rikoorka.
Qaybaha:
Tani waa halka aan ku caddeyno waxa tusmadayadu ka kooban tahay. Waxay ka kooban tahay hal qayb - goobta ugu horeysa ee aan isticmaali doono, ku qor aan saxeexin - integer togan. Inta aan ka xasuusto dukumeentiyada, tirada ugu badan ee noqon karta waa 18 quintillion. Wax badan oo cajiib ah.
Waxaan markaas gelin karnaa xogta anagoo adeegsanayna amarka gelista.

Soo saarista xogta
Markaa waxaan ku soo bandhigi karnaa xogta amarka xulashada.
Box.example.select oo wata furaha {1} ayaa muujin doona galitaanka la rabo. Haddii aan ka tagno furaha, waxaan arki doonaa dhammaan diiwaanada aan hayno. Dhammaantood way ku kala duwan yihiin tirada tiirarka, laakiin halkan, mabda'a, ma jiraan fikradda tiirarka - waxaa jira tirooyin goobeed.
Waxaa jiri kara gabi ahaanba xogta aad rabto. Iyo tusaale ahaan, waxaan u baahanahay inaan ka raadinno goobta labaad. Si tan loo sameeyo, waxaanu samaynaa tusaha sare ee cusub.
box.space.example:create_index( ‘secondary’, { type = ‘TREE’, unique = false, parts = {{field = 2, type =’string’} }})
Waxaan isticmaalnaa amarka Create_index.
Waxaan ugu yeernaa Secondary.
Taas ka dib, waxaad u baahan tahay inaad qeexdo xuduudaha. Nooca tusmadu waa GEED. Waxa laga yaabaa inaanay ahayn mid gaar ah, markaa waxaanu galnaa Unique = been.
Kadibna waxaynu tilmaannaa qaybaha tusmadayadu ka kooban tahay. Goobtu waa tirada goobta aan ku xidhno tusmada, oo aynu qeexno nooca xargaha. Oo sidaas ayaa loo abuuray.

Ilaalinta
Haddii aan dib u bilowno tusaalaha oo aan isku dayno inaan mar kale wacno xogta, waxaan arki doonaa inaysan halkaas joogin - wax walba waa madhan. Tani waxay dhacdaa sababtoo ah Tarantool waxay samaysaa isbaarooyin waxayna kaydisaa xogta diskka, laakiin haddii aan joojino shaqada ka hor kaydinta soo socota, waxaan lumin doonaa dhammaan hawlgallada - sababtoo ah waxaan ka soo kabsan doonaa isbaarada ugu dambeysa, tusaale ahaan, laba saacadood ka hor.
Badbaadinta ilbiriqsi kasta sidoo kale ma shaqeyn doonto - sababtoo ah si joogto ah ugu daadinta 20 GB diskka waa fikrad sidaas ah.
Taas awgeed, fikradda qorista-hor-qorista waa la allifay oo la hirgeliyay. Caawinteeda, isbeddel kasta oo ku yimaadda xogta, diiwaan ayaa lagu abuurayaa fayl yar oo hore u qoran.
Geli kasta oo ilaa barta kantaroolka ayaa lagu kaydiyaa iyaga. Faylashaas, waxaanu dejinay cabbirka - tusaale ahaan, 64 mb. Marka ay buuxiso, duubitaanku wuxuu bilaabmaa inuu aado faylka labaad. Iyo dib u bilaabashada ka dib, Tarantool waxa ay ka soo kabsanaysaa isbaaradii u dambaysay ka dibna waxa ay rogtay dhammaan wax kala iibsiga dambe ilaa ay joogsato.
Si aad u sameyso duubista noocaas ah, waxaad u baahan tahay inaad ku qeexdo ikhtiyaarka sanduuqa.cfg settings (kujira faylka example.lua):
wal_mode = “write”;isticmaalka xogta
Waxa aan hadda qornay, waxaad isticmaali kartaa Tarantula si aad u kaydiso xogta waxayna u shaqayn doontaa si dhakhso leh xog ururin ahaan. Oo hadda cherry on cake - maxaad ku samayn kartaa oo dhan.

root@test2:/#Calaamadaha ayaa la soo saaray. Oo waxaan si joogto ah u duubnaa xogta. 99% codsiyada waxa lagu dhameeyay 42 millise seconds. Sidaa darteed, waxaan ku haynaa qiyaastii 3500 codsi ilbiriqsi kasta mashiinka yar, halkaas oo ay jiraan 2 cores iyo 4 gigabytes oo xusuusta ah.
Waxa kale oo aad dooran kartaa qaar ka mid ah 50000 token oo aad aragto qiimaheeda.
Ma isticmaali kartid http oo keliya, waxaad socodsiisaa hawlaha asalka ah ee ka baaraandegaya xogtaada. Intaa waxaa dheer, waxaa jira kiciyeyaasha kala duwan. Tusaale ahaan, waxaad wici kartaa hawlaha ku saabsan cusbooneysiinta, hubi wax - hagaajin khilaafaadka.
Waxaad si toos ah ugu qori kartaa codsiyada qoraalka ee server-ka xogta laftiisa, oo aan lagu xaddidin wax kasta, ku xidh qaybo kasta oo hirgeli wax kasta oo macquul ah.
Adeegaha codsigu waxa uu geli karaa server-yada dibadda, ururin xogta oo ku dari kara xogtiisa. Xogta xogtan waxaa isticmaali doona codsiyo kale.
Tan waxaa samayn doona Tarantula laftiisa, mana jirto baahi loo qabo in la qoro codsi gaar ah.
Gabagabada
Tani waa kaliya qaybta koowaad ee shaqada weyn. Midka labaad ayaa si dhakhso ah loogu daabici doonaa barta kooxda Mail.ru, waxaana hubaal ah inaan ku dari doono isku xirka walxahan.
Haddii aad xiisaynayso inaad ka qaybgasho munaasabadaha aan ku abuurno waxyaalahan onlaynka oo aad su'aalo ku waydiinayso wakhtiga dhabta ah, ku xidhnow.
Haddii aad u baahan tahay inaad u guurto daruuraha ama aad wax su'aalo ah ka qabto kaabayaashaaga, .
PS Waxaanu haynaa 2 xisaab xidh oo bilaash ah bishii, laga yaabee in mashruucaagu uu ka mid noqdo.
