Quinque annos cum Tarantool laborare conabar, sed tunc mihi non laborabat. Sed nuper webinarem tenebam ubi de Hadoop locutus sum et quomodo opera MapReduce. Ibi quaesiverunt mihi: "Quare Tarantool non utimur ad hoc opus?"
Ex curiositate ad illud reverti decrevi, versionem novissimam experire - quod tempus vere consilium probavi. Nunc ostendam tibi quomodo simplici applicatione in Tarantool scriberes, eam onere et eius perficiendi deprime, et videbis quam omnia facilia et frigida sint.
Quid est Tarantool
Tarantool positiones ipsae databases ut ultra-celeriter. Potes ponere aliquem datam quam voles ibi. Plus, replica, testa, id est, ingentem copiam notitiarum per plures ministros scinde et proventus ex eis coniunge - hospites domini domini culpabiles tolerantes efficiunt.
Secundo hoc est applicatio servo. Applicationes tuas in eo scribere potes, cum data operare, exempli gratia, vetera monumenta in curriculo delere secundum certas regulas. Scribere potes servo Http directe in Tarantula quae cum notitia operabitur: da quantitatem eorum, novas notitias ibi scribe et omnia ad dominum redige.
Articulum legi quomodo guys nuntium queue de 300 lineis fecerunt, quod simpliciter rumpitur et irruit - minimum habent observantiam 20 nuntii per alterum. Hic circumagi vere potes et scribe amplissimum applicationem, et non repone sicut in PostgreS.
Conabor aliquid simile huic servo describere, solum simplex, in hoc articulo.
occasum
Pro experimento, tres vexillum virtualis machinis incepi - a 20 GB ferreus coegi, Ubuntu 18.04. 2 virtual CPUs and 4 gigs of memory.
Tarantool instituimus - scripturae verissimae currite vel repositorium addimus et aptum fac ut Tarantool install instituamus. Link to script - (CURL -L | VER=2.4 sudo -E bash). Imperat tibi sicut nos;
tarantoolctl — Praecipuum praeceptum ad instantias administrandas Tarantula.
/etc/tarantool — Tota figura hie est.
var/log/tarantool — Hic sunt tigna.
var/lib/tarantool — Notitia hic jacet, et tunc dividitur in Instantias.
Sunt folder instantiae-praesto et instantiae activae - continet quod deducetur - exemplum configuration lima cum lua codice, qui describit quid portus auscultat, quae memoria praesto est ei, Vinyl machinae occasus, codicem qui currit in startup. servientes, obstrictio, queues, deletio obsoleta data, et sic porro.
Instantiae operantur similia in PostgreS. Exempli gratia, vis plura exemplaria currere database quae in diversis portibus pendent. Evenit ut nonnullae instantiae database in uno servo deductae, quae in diversis portibus pendent. Possunt habere prorsus diversa loca, unum exemplum efficiens unam logicam, alteram aliam.
Instantia procuratio
Habemus mandatum tarantoolctl, quod permittit tibi instantiam Tarantulam administrare. Exempli gratia, exemplum reprehendo tarantoolctl limam configurationem reprehendo et dices - tabella est ok si nullae ibi syntaxin errores sunt.
Status instantiae videre potes — status exempli tarantoolctl. Eodem modo potes incipere, desine, sileo.
Cum instantia currit, duobus modis ei coniungere potes.
1. administrativus consolatorium
Defalta, Tarantool nervum aperit, textus normales ASCII illuc missus est ad imperium Tarantool. Nexus ad consolatorium semper occurrit sub user admin, nulla authenticatio, ut non opus est ad portum consolatorium extra Tarantulam administrare.
Hanc methodo utens coniungere, Tarantoolctl nomen instantia inire debes. Praeceptum consolatorium deducet et pro usuario admin connectet. Numquam extra portum consolatorium exponere - melius est eam relinquere quam nervum unitatis. Tunc soli qui accessum habent ad scribendum nervum, Tarantulam coniungere poterunt.
Haec methodus necessaria est rebus administrativis. Laborare cum notitia, utere methodo secunda - protocollo binarii.
2. Using binarii protocol ad coniungere ad portum specifica
Configuratio directivam continet audientium, quae portum communicationum externarum aperit. Portus hic adhibetur cum protocollo binarii et ibi datur authenticas.
Ad hanc connexionem, tarantoolctl iungo ad numerum portum adhibetur. Utens, coniungere cum servientibus remotis potes, authenticas utere et variis accessibus iura dare.
Data Book and Box OMNIBUS
Cum Tarantool database et applicatio est et server, varios modulos habet. Quaeritur in moduli archa - in instrumentis operandis cum notitia. Cum aliquid scribes in arca, Tarantool scribit notitias orbis, in memoria reponit aut aliquid aliud agit.
record
Exempli gratia, in capsam moduli imus et munus in box.once vocamus. Hoc Tarantool coget ad nostrum codicem currere cum minister initialisatur. Spatium creamus in quo notitia nostra reponenda erit.
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')
endPost hoc primum indicem - primarium efficimus per quem notitias quaerere possumus. Defalta, si ambitum aliquem non definis, primus campus in singulis tabulis pro indice primario adhibebitur.
Deinde concedimus usori hospitis, sub quo per protocollum binarii coniungimus. Concedimus legentes, scribentes et exequentes per totam instanciam.
Comparari ad databases conventionales, omnia hic satis simplicia sunt. Spatium habemus - spatium in quo notitia nostra simpliciter reponitur. Quisque a tuplum dicitur testimonium. Is packaged in MessagePack. Forma haec frigidissima est - binarius est et minus spatium sumit 18 bytes versus 27 .
Commodum elaboraret eum. Fere omnes lineae, singulae notitiae monumentorum columnas omnino diversas habere possunt.
Omnia spatia potes uti ad Box.space imperium. Instantia specifica eligere, exemplum scribe box.space et integram informationem de eo accipias.
Tarantool duas machinas aedificatas habet: Memoria et Vinyl. Memoria omnes notitias in memoriam reponit. Ergo omnia simpliciter et cito operatur. Notitia discriminis rasurae est, et est etiam mechanismum logatum scribere, ideo nihil amittemus si ingruat server.
Vinyl recondit notitias orbis in forma familiarius nobis - hoc est, plura notitia quam memoriam habere potes, et Tarantula ex orbe leget.
Nunc enim Memoria utemur.

conservatam agnovimus
Si instantiam sileo et iterum notitias vocare conamur, videbimus quod ibi non est - omnia vana sunt. Hoc fit quia Tarantool facit checks et notitias orbis salvat, sed si operari cessamus usque ad proximum salvare, omnes operationes amittemus - quia ex ultimo LAPIS recuperabimus, quod erat, exempli gratia duas horas ante.
Alterum alterum servare non laborabit, quia continue dumping 20 GB in disco utilem non est.
Ad hoc, conceptus praemisit stipes scribendae inventa et perficienda. Auxiliante, ad omnem mutationem datam, introitus creatur in parva tabella praemissorum scribendarum.
Quisque introitus usque ad LAPIS in eis reponitur. Pro his fasciculis magnitudinem ponimus - exempli gratia 64 MB. Cum plenum sit, tabula ad secundam incipit ire. Et post sileo, Tarantool ex ultimo LAPIS restituitur et deinde per omnia posteriora negotia volvitur donec subsistat.
Ad huiusmodi tabulas faciendas, optionem in archa.cfg occasus (in exemplo.lua lima);

Cum his quae nunc scripsimus, Tarantula uti potes ad notitias congregendas et celerrime database operabitur. Nunc in vico placenta est quod facere potes cum omnibus.
