Makore mashanu apfuura ndakaedza kushanda neTarantool, asi zvakashaya basa kwandiri. Asi nguva pfupi yadarika ndakabata webinar kwandakataura nezve Hadoop, nezve mashandiro anoita MapReduce. Ikoko ndakabvunzwa mubvunzo - "Sei usingashandisi Tarantool pabasa iri?".
Nekuda kwekuda kuziva, ndakafunga kudzokera kwairi, kuyedza yazvino vhezheni - uye panguva ino ndakanyanya kufarira chirongwa ichi. Iye zvino ini ndicharatidza maitiro ekunyora nyore application muTarantool, itakure uye tarisa kuita, uye iwe uchaona kuti zviri nyore uye zvinotonhorera zvese zviripo.
Chii chinonzi Tarantool
Tarantool inozviisa pachayo seyekupedzisira-inokurumidza dhatabhesi. Iwe unogona kuisa chero data yaunoda imomo. Uyezve, vadzokorore, shard - ndiko kuti, patsanura huwandu hukuru hwe data pamasevha akati wandei uye sanganisa mibairo kubva kwavari - ita kukanganisa-kushivirira master-master link.
Chechipiri, iapplication server. Iwe unogona kunyora zvikumbiro zvako pairi, shanda nedata, semuenzaniso, bvisa zvinyorwa zvekare kumashure maererano nemimwe mitemo. Iwe unogona kunyora sevha yeHttp zvakananga muTarantula iyo ichashanda nedata: ipa nhamba yavo, nyora data nyowani ipapo uye udzikise zvese kune tenzi.
Ndakaverenga chinyorwa pamusoro pekuti vakomana vakaita sei mutsara wemutsara we300, unongove misodzi nekurova - vane hushoma hwekuita kwemameseji makumi maviri pasekondi. Pano iwe unogona kunyatso kutendeuka nekunyora yakakura kwazvo application, uye izvi hazvichengetwe, senge muPostgreS.
Inenge sevha yakadaro, iri nyore chete, ini ndichaedza kutsanangura munyaya ino.
Kuiswa
Paye bvunzo, ndakatanga matatu akajairwa chaiwo muchina - 20 gigabyte hard drive, Ubuntu 18.04. 2 virtual CPU uye 4 gigabytes yekuyeuka.
Isu tinoisa Tarantool - mhanyisa bash script kana kuwedzera repository uye ita apt kuwana kuisa Tarantool. Batanidza kune script - (curl -L | VER=2.4 sudo -E bash). Tine mirairo yakaita se:
tarantoolctl ndiwo murairo mukuru wekutonga Tarantula zviitiko.
/etc/tarantool - pano pane kurongeka kwese.
var/log/tarantool - heino matanda.
var/lib/tarantool - heino nhema iyo data, uye zvino inokamurwa kuita zviitiko.
Kune mienzaniso-inowanikwa uye semuenzaniso-inogonesa maforodha - ine izvo zvichatangwa - iyo yekumisikidza faira ine lua kodhi, iyo inotsanangura kuti ndeapi madoko ainoteerera pairi, ndeipi ndangariro inowanikwa kwairi, Vinyl injini marongero, kodhi inoshanda pakutanga. maseva, sharding, mitsetse, kudzima data isingachashandi, zvichingodaro.
Mamiriro anoshanda senge muPostgreS. Semuenzaniso, iwe unoda kumhanyisa akawanda makopi edhatabhesi inorembera pamadoko akasiyana. Zvinoitika kuti akati wandei dhatabhesi zviitiko zvinotangwa pane imwe sevha, iyo inorembera pamadoko akasiyana. Ivo vanogona kuve neyakasiyana marongero - imwe muenzaniso inoshandisa imwe pfungwa, yechipiri - imwe.
Instance management
Isu tine tarantoolctl yekuraira iyo inotibvumira kubata Tarantula zviitiko. Semuenzaniso, tarantoolctl cheki muenzaniso inotarisa faira yekumisikidza uye iti iyo faira yakanaka kana pasina zvikanganiso zvesyntax.
Iwe unogona kuona chimiro chemuenzaniso - tarantoolctl chimiro muenzaniso. Nenzira imwecheteyo, iwe unogona kuita kutanga, kumisa, kutangazve.
Kana imwe muenzaniso yave kushanda, pane nzira mbiri dzekubatanidza nayo.
1. Administrative console
Nekutadza, Tarantool inovhura socket uye inotumira yakajeka ASCII mameseji kudzora iyo Tarantula. Kubatanidza kune koni kunogara kuchiitika pasi pemushandisi we admin, hapana humbowo, saka haufanire kutora chiteshi chekoni kudzora Tarantula kunze.
Kuti ubatanidze neiyi nzira, unofanirwa kupinda Tarantoolctl pinda zita remuenzaniso. Iwo murairo uchavhura console uye ubatanidze semushandisi we admin. Usambofa wakafumura iyo console port kune kunze - zviri nani kuisiya seyuniti socket. Zvadaro chete avo vane ruzivo rwekunyora kune socket ndivo vachakwanisa kubatana neTarantula.
Iyi nzira inodiwa pazvinhu zvekutonga. Kuti ushande nedata, shandisa nzira yechipiri - iyo binary protocol.
2. Kushandisa binary protocol kuti ubatanidze kune imwe chiteshi
Pane kuraira kwekuteerera mukugadzirisa, iyo inovhura chiteshi chekutaura kwekunze. Chiteshi ichi chinoshandiswa nebhinari protocol uye kutendeseka kunogoneswa ipapo.
Kune iyi yekubatanidza, tarantoolctl yekubatanidza kune nhamba yechiteshi inoshandiswa. Kuishandisa, unogona kubatana kumaseva ari kure, shandisa chokwadi uye upe akasiyana kodzero dzekuwana.
Data Kurekodha uye Bhokisi Module
Sezvo Tarantool iri zvese dhatabhesi uye sevha yekushandisa, ine akasiyana mamodule. Isu tinofarira mubhokisi module - inoshandisa kushanda nedata. Paunonyora chimwe chinhu kubhokisi, Tarantool inonyora iyo data kudhisiki, inoichengeta mundangariro, kana kuita chimwe chinhu nayo.
Rekodhi
Semuenzaniso, tinopinda mubhokisi module uye kudana bhokisi.once basa. Ichamanikidza Tarantool kumhanya kodhi yedu kana sevha yatangwa. Isu tinogadzira nzvimbo iyo data yedu ichachengetwa.
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')
endMushure meizvozvo, isu tinogadzira yekutanga index - yekutanga - yatinogona kutsvaga data. By default, kana pasina parameters inotsanangurwa, yekutanga ndima mune yega yega yekupinda yeiyo primer index ichashandiswa.
Zvadaro tinoita rubatsiro kune muenzi mushandisi, pasi payo patinobatanidza kuburikidza nebhinari protocol. Isu tinobvumira kuverenga, kunyora uye kuita muchiitiko chese.
Kuenzaniswa neyakajairwa dhatabhesi, zvese zviri nyore pano. Tine nzvimbo - nzvimbo iyo data yedu inongochengetwa. Kupinda kwega kwega kunonzi tuple. Iyo yakarongedzwa muMessagePack. Iyi imhando inotonhorera - ndeye binary uye inotora nzvimbo shoma - 18 bytes maringe ne27.
Zviri nyore kushanda naye. Anenge mutsara wega wega, yega yega yekupinda data inogona kuve nemakoramu akasiyana zvachose.
Tinogona kuona nzvimbo dzese tichishandisa Box.space command. Kuti tisarudze muenzaniso chaiwo, tinonyora bhokisi.space muenzaniso uye tinowana ruzivo rwakazara pamusoro payo.
Kune mhando mbiri dzeinjini dzakavakwa muTarantool: Memory uye Vinyl. Memory inochengeta data rese mundangariro. Naizvozvo, zvese zvinoshanda zviri nyore uye nekukurumidza. Iyo data inokandwa kune dhisiki, uye kune zvakare yekunyora pamberi pegi mecha, saka isu hatirasikirwe chero chinhu kana sevha ikaparara.
Vinyl inochengetedza data pane dhisiki mune yakajairika fomu - ndiko kuti, iwe unogona kuchengeta data rakawanda kupfuura isu tine ndangariro, uye Tarantula ichaiverenga kubva kudhisiki.
Iye zvino tichashandisa Memory.
