Zosta\u0142a wydana pierwsza publiczna wersja projektu MangoDB, kt\u00f3ry oferuje warstw\u0119 implementuj\u0105c\u0105 protok\u00f3\u0142 dokumentowej bazy danych MongoDB, dzia\u0142aj\u0105c\u0105 na bazie danych PostgreSQL. Projekt ma na celu umo\u017cliwienie migracji aplikacji korzystaj\u0105cych z bazy danych MongoDB do PostgreSQL oraz zapewnienie ca\u0142kowicie otwartego stosu oprogramowania. Kod zosta\u0142 napisany w j\u0119zyku Go i jest dystrybuowany na licencji Apache 2.0. <\/p>\n

Program dzia\u0142a w formie proxy, kt\u00f3re translatuje zapytania do MangoDB na zapytania SQL do PostgreSQL, u\u017cywaj\u0105c PostgreSQL jako rzeczywistego magazynu. Projekt jest kompatybilny z sterownikami dla MongoDB, ale obecnie znajduje si\u0119 w fazie prototypu i nie obs\u0142uguje zaawansowanych funkcji protoko\u0142u MongoDB, chocia\u017c jest ju\u017c przydatny do portowania prostych aplikacji. <\/p>\n

Potrzeba odej\u015bcia od korzystania z bazy danych MongoDB mo\u017ce wynika\u0107 z przej\u015bcia projektu na niedarmow\u0105 licencj\u0119 SSPL, kt\u00f3ra opiera si\u0119 na licencji AGPLv3, ale nie jest otwarta, poniewa\u017c zawiera dyskryminuj\u0105ce wymagania dotycz\u0105ce dostarczania na licencji SSPL nie tylko kodu samej aplikacji, ale tak\u017ce kod\u00f3w \u017ar\u00f3d\u0142owych wszystkich komponent\u00f3w zaanga\u017cowanych w \u015bwiadczenie us\u0142ugi w chmurze. <\/p>\n

Przypomnijmy, \u017ce MongoDB zajmuje nisz\u0119 mi\u0119dzy szybkim i skalowalnym systemami zarz\u0105dzania danymi w formacie klucz\/warto\u015b\u0107 a relacyjnymi DBMS, kt\u00f3re s\u0105 funkcjonalne i wygodne w formu\u0142owaniu zapyta\u0144. MongoDB obs\u0142uguje przechowywanie dokument\u00f3w w formacie podobnym do JSON, ma do\u015b\u0107 elastyczny j\u0119zyk do formu\u0142owania zapyta\u0144, mo\u017ce tworzy\u0107 indeksy dla r\u00f3\u017cnych przechowywanych atrybut\u00f3w, skutecznie zapewnia przechowywanie du\u017cych obiekt\u00f3w binarnych, wspiera rejestrowanie operacji na zmianach i dodawaniu danych do bazy danych, mo\u017ce dzia\u0142a\u0107 zgodnie z paradygmatem Map\/Reduce, wspiera replikacj\u0119 i budowanie konfiguracji odpornych na awarie.
