Esimene avalik v\u00e4ljaanne MangoDB projektist on saadaval, pakkudes kihti dokumentide orienteeritud andmebaasi MongoDB protokolli rakendust, mis t\u00f6\u00f6tab PostgreSQL andmebaasi kohal. Projekt on suunatud rakenduste migratsiooni v\u00f5imaldamisele, mis kasutavad MongoDB andmebaasi PostgreSQL-ile ja t\u00e4iesti avatud tarkvarastekele. Kood on kirjutatud Go keeles ja levitatakse Apache 2.0 litsentsi alusel. <\/p>\n

Programm t\u00f6\u00f6tab proksina, edastades p\u00e4ringud MangoDB-st SQL-k\u00fcsimusteks PostgreSQL-le, kasutades PostgreSQL-i tegeliku salvestusena. Projekt on \u00fchilduv MongoDB draiveritega, kuid on praegu protot\u00fc\u00fcbi staadiumis ja ei toeta laiendatud MongoDB protokolli funktsioone, kuigi see on juba sobiv lihtsate rakenduste t\u00f5lkimiseks. <\/p>\n

Vajadus eemalduda MongoDB andmebaasi kasutamisest v\u00f5ib tekkida seoses projekti \u00fcleminekuga mitteavaldatud SSPL litsentsile, mis on p\u00f5hinenud AGPLv3 litsentsil, kuid ei ole avatud, kuna see sisaldab diskrimineerivat n\u00f5uet, et SSPL litsentsi alusel peab jagama mitte ainult rakenduse koodi, vaid ka k\u00f5ikide komponentide l\u00e4htekode, mis on seotud pilveteenuse osutamisega. <\/p>\n

Tuletame meelde, et MongoDB h\u00f5ivab ni\u0161i kiirete ja skaleeritavate s\u00fcsteemide vahel, mis t\u00f6\u00f6tlevad andmeid v\u00f5tme\/v\u00e4\u00e4rtuse formaadis, ning relatsiooniliste andmebaaside, mis on funktsionaalsed ja mugavad p\u00e4ringute koostamiseks. MongoDB toetab dokumentide salvestamist JSON-taolisel kujul, tal on piisavalt paindlik p\u00e4ringute koostamise keel, ta suudab luua indekseid erinevate salvestatud atribuutide jaoks, t\u00f5husalt haldab suurte binaarobjektide salvestamist, toetab tegevuste ajalugu andmete muutmisel ja lisamisel andmebaasi, v\u00f5ib t\u00f6\u00f6tada Map\/Reduce paradigmas, toetab replikatsiooni ja veakindlate konfiguratsioonide loomist.
