Zaka zisanu zapitazo ndinayesa kugwira ntchito ndi Tarantool, koma sizinandithandize. Koma posachedwa ndidakhala ndi webinar pomwe ndidalankhula za Hadoop ndi momwe MapReduce imagwirira ntchito. Kumeneko adandifunsa funso: "Bwanji osagwiritsa ntchito Tarantool pa ntchitoyi?"
Chifukwa cha chidwi, ndinaganiza zobwereranso, kuyesa mtundu waposachedwa - ndipo nthawi ino ndimakonda kwambiri ntchitoyi. Tsopano ndikuwonetsani momwe mungalembere pulogalamu yosavuta ku Tarantool, kuyiyika ndikuyang'ana momwe imagwirira ntchito, ndipo muwona momwe zonse zilili zosavuta komanso zoziziritsa.
Tarantool ndi chiyani
Tarantool imadziyika yokha ngati nkhokwe yachangu kwambiri. Mutha kuyika deta iliyonse yomwe mukufuna pamenepo. Kuphatikiza apo, bwerezaninso, shard - ndiko kuti, kugawaniza kuchuluka kwa data pamaseva angapo ndikuphatikiza zotsatira kuchokera kwa iwo - pangani kulumikizana kosalekeza kwa master-master.
Kachiwiri, iyi ndi seva yofunsira. Mutha kulemba mapulogalamu anu pamenepo, gwiritsani ntchito ndi data, mwachitsanzo, chotsani zolemba zakale kumbuyo malinga ndi malamulo ena. Mutha kulemba seva ya Http mwachindunji ku Tarantula yomwe ingagwire ntchito ndi data: perekani kuchuluka kwawo, lembani deta yatsopano pamenepo ndikuchepetsa zonse kwa mbuye.
Ndinawerenga nkhani ya momwe anyamatawo adapangira mzere wa uthenga wa mizere ya 300, yomwe ikungophulika ndikuthamanga - ali ndi ntchito yochepa ya mauthenga a 20 pamphindi. Apa mutha kutembenuka ndikulemba pulogalamu yayikulu kwambiri, ndipo sikhala yosungirako, monga mu PostgreS.
Ndiyesera kufotokoza chinachake chonga seva iyi, yosavuta, m'nkhaniyi.
kolowera
Pakuyesa, ndidayambitsa makina atatu okhazikika - 20 GB hard drive, Ubuntu 18.04. 2 ma CPU enieni ndi ma gigs 4 a kukumbukira.
Timayika Tarantool - yendetsani bash script kapena yonjezerani malo osungira ndikukhazikitsa Tarantool. Lumikizani ku script - (curl -L | | VER = 2.4 sudo -E bash). Tili ndi malamulo monga:
tarantoolctl - lamulo lalikulu pakuwongolera zochitika za Tarantula.
/etc/tarantool - apa pali kasinthidwe konse.
var/log/tarantool - apa pali mitengo.
var/lib/tarantool - deta ili apa, ndiyeno imagawidwa muzochitika.
Pali zikwatu zomwe zilipo komanso zomwe zimathandizira - zili ndi zomwe zidzayambike - fayilo yosinthira chitsanzo ndi lua code, yomwe imalongosola madoko omwe amamvetsera, kukumbukira komwe kulipo, makina a injini ya Vinyl, code yomwe imayambira poyambira. ma seva, sharding, mizere, kufufutidwa kwa data yosatha, ndi zina zotero.
Zochitika zimagwira ntchito ngati PostgreS. Mwachitsanzo, mukufuna kuyendetsa makope angapo a database yomwe imapachikidwa pamadoko osiyanasiyana. Zikuwonekeratu kuti zochitika zingapo za database zimayambitsidwa pa seva imodzi, yomwe imapachikidwa pamadoko osiyanasiyana. Atha kukhala ndi makonda osiyanasiyana - nthawi imodzi imagwiritsa ntchito malingaliro amodzi, yachiwiri - ina.
Kasamalidwe ka zochitika
Tili ndi lamulo la tarantoolctl, lomwe limakupatsani mwayi wowongolera zochitika za Tarantula. Mwachitsanzo, tarantoolctl cheke chitsanzo chiyang'ana fayilo yosinthira ndikuti - fayilo ili bwino ngati palibe zolakwika za syntax pamenepo.
Mutha kuwona momwe chiwonetserochi chikuyendera - chitsanzo cha tarantoolctl. Momwemonso mutha kuyambitsa, kuyimitsa, kuyambiranso.
Chitsanzo chikayamba, mutha kulumikizana nacho m'njira ziwiri.
1. Administrative console
Mwachikhazikitso, Tarantool imatsegula socket, zolemba za ASCII zokhazikika zimatumizidwa kumeneko kuti ziwongolere Tarantool. Kulumikizana ndi kontrakitala kumachitika nthawi zonse pansi pa wogwiritsa ntchito admin, palibe kutsimikizika, kotero palibe chifukwa chosinthira doko la console kuti muyendetse Tarantula.
Kuti mulumikizane ndi njirayi, muyenera kulowa Tarantoolctl lowetsani dzina lachitsanzo. Lamulo lidzayambitsa console ndikugwirizanitsa ngati wogwiritsa ntchito admin. Osawonetsa doko la console kunja - ndibwino kulisiya ngati socket ya unit. Ndiye okhawo omwe ali ndi mwayi wolembera ku socket adzatha kulumikiza ku Tarantula.
Njirayi ndiyofunikira pazinthu zoyang'anira. Kuti mugwiritse ntchito deta, gwiritsani ntchito njira yachiwiri - protocol binary.
2. Kugwiritsa ntchito ndondomeko ya binary kuti mugwirizane ndi doko linalake
Kukonzekera kuli ndi malangizo omvera, omwe amatsegula doko la mauthenga akunja. Dokoli limagwiritsidwa ntchito ndi protocol ya binary ndipo kutsimikizika kumayatsidwa pamenepo.
Pakulumikiza uku, tarantoolctl yolumikizana ndi nambala ya doko imagwiritsidwa ntchito. Pogwiritsa ntchito, mutha kulumikizana ndi ma seva akutali, gwiritsani ntchito kutsimikizira ndikupereka maufulu osiyanasiyana opezeka.
Kujambula kwa Data ndi Bokosi Module
Popeza Tarantool ndi nkhokwe komanso seva yogwiritsira ntchito, ili ndi ma module osiyanasiyana. Tili ndi chidwi ndi gawo la bokosi - limagwiritsa ntchito data. Mukalemba chinachake ku bokosi, Tarantool imalemba deta ku disk, kuisunga pamtima, kapena kuchita china chake.
Jambulani
Mwachitsanzo, timalowa mu gawo la bokosi ndikuyitana bokosi.once ntchito. Izi zidzakakamiza Tarantool kuyendetsa nambala yathu seva ikakhazikitsidwa. Timapanga malo omwe deta yathu idzasungidwe.
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')
endPambuyo pake, timapanga cholozera choyambirira - choyambirira - chomwe tingathe kufufuza deta. Mwachikhazikitso, ngati simutchula magawo aliwonse, gawo loyamba muzolemba zilizonse lidzagwiritsidwa ntchito pa index yoyambirira.
Kenaka timapereka chithandizo kwa wogwiritsa ntchito alendo, pomwe timagwirizanitsa kudzera mu binary protocol. Timalola kuwerenga, kulemba ndi kuchita pazochitika zonse.
Poyerekeza ndi nkhokwe wamba, zonse apa ndi zosavuta. Tili ndi malo - malo omwe deta yathu imasungidwa. Mbiri iliyonse imatchedwa tuple. Imayikidwa mu MessagePack. Uwu ndi mtundu wabwino kwambiri - ndi wachiphamaso ndipo umatenga malo ochepa - 18 byte motsutsana ndi 27.
Ndi bwino ntchito naye. Pafupifupi mzere uliwonse, zolemba zonse za data zimatha kukhala ndi magawo osiyanasiyana.
Titha kuwona mipata yonse pogwiritsa ntchito lamulo la Box.space. Kuti musankhe chochitika china, lembani chitsanzo cha box.space ndikupeza zambiri za izo.
Tarantool ili ndi injini ziwiri zomangidwa: Memory ndi Vinyl. Memory imasunga zonse zokumbukira. Choncho, zonse zimagwira ntchito mosavuta komanso mofulumira. Deta imasiyidwa ku diski, ndipo palinso njira yolembera kutsogolo, kotero sitidzataya chilichonse ngati seva ikugwa.
Vinyl amasunga deta pa disk mu mawonekedwe omwe timawadziwa bwino - ndiko kuti, mukhoza kusunga zambiri kuposa zomwe timakumbukira, ndipo Tarantula adzaiwerenga kuchokera ku disk.
Pakadali pano tigwiritsa ntchito Memory.

Kusungidwa
Ngati tiyambitsanso chitsanzo ndikuyesera kuyimbanso deta, tiwona kuti palibe - zonse zilibe kanthu.

Sizigwira ntchito kupulumutsa sekondi iliyonse, chifukwa kutaya 20 GB nthawi zonse pa disk si lingaliro labwino.
Pachifukwa ichi, lingaliro la kulemba-patsogolo linapangidwa ndikugwiritsidwa ntchito. Ndi chithandizo chake, pakusintha kulikonse kwa data, cholowera chimapangidwa mu fayilo yaing'ono yolemba patsogolo.

root@test2:/#Zizindikiro zimaperekedwa. Ndipo timalemba zambiri nthawi zonse. 99% ya zopempha zidakonzedwa mu 42 milliseconds. Chifukwa chake, tili ndi zopempha za 3500 pa sekondi imodzi pamakina ang'onoang'ono okhala ndi ma cores a 2 ndi ma gigabytes 4 a kukumbukira.
Mutha kusankhanso chizindikiro cha 50000 ndikuwona mtengo wake.
Simungagwiritse ntchito http, komanso kuyendetsa ntchito zakumbuyo zomwe zimagwiritsa ntchito deta yanu. Komanso pali zoyambitsa zosiyanasiyana. Mwachitsanzo, mutha kuyimbira ntchito pazosintha, fufuzani china - mikangano yolondola.
Mutha kulemba zolemba za script mwachindunji mu seva ya database yokha, ndipo osakhala ndi malire ndi chilichonse, lumikizani ma module aliwonse ndikukhazikitsa malingaliro aliwonse.
Seva yogwiritsira ntchito imatha kupeza ma seva akunja, kupeza deta ndikuyiwonjezera ku database yake. Deta kuchokera ku databaseyi idzagwiritsidwa ntchito ndi mapulogalamu ena.
Tarantula idzachita izi yokha, ndipo simudzasowa kulemba ntchito yosiyana.
Pomaliza
Ichi ndi gawo loyamba la ntchito yaikulu. Yachiwiri isindikizidwa posachedwa pa blog ya Mail.ru Gulu, ndipo tidzawonjezera ulalo pankhaniyi.
Ngati mukufuna kupita ku zochitika zomwe timapanga zinthu izi pa intaneti ndikufunsa mafunso munthawi yeniyeni, mvetserani.
Ngati mukufuna kusamukira kumtambo kapena kukhala ndi mafunso okhudza zomangamanga zanu, .
PS Tili ndi zowerengera zaulere 2 pamwezi, mwina polojekiti yanu ikhala imodzi mwazo.
