Objavljen je izdanak projekta FerretDB 0.3, koji omogu\u0107ava zamenu dokumentno-orijentisane DBMS MongoDB sa PostgreSQL bez promene u kodu aplikacija. FerretDB funkcioni\u0161e kao proxy server koji prevodi zahteve za MongoDB u SQL upite za PostgreSQL, \u0161to omogu\u0107ava kori\u0161\u0107enje PostgreSQL kao stvarnog skladi\u0161ta. Kod je napisan u programskom jeziku Go i distribuira se pod Apache 2.0 licencom. <\/p>\n

Potrebna migracija mo\u017ee nastati usled prelaska MongoDB na zatvorenu licencu SSPL, koja se temelji na AGPLv3 licenci, ali nije otvorena, jer sadr\u017ei diskrimini\u0161u\u0107i zahtev da se isporu\u010duje ne samo kod same aplikacije, ve\u0107 i izvorni kod svih komponenti uklju\u010denih u pru\u017eanje cloud usluge pod SSPL licencom. <\/p>\n

Glavna ciljna publika FerretDB su korisnici koji ne koriste napredne mogu\u0107nosti MongoDB u svojim aplikacijama, ali \u017eele da koriste potpuno otvoreni softverski staklenak. U trenutnoj fazi razvoja, FerretDB podr\u017eava samo deo mogu\u0107nosti MongoDB, koje se naj\u010de\u0161\u0107e koriste u standardnim aplikacijama. U budu\u0107nosti planiraju da postignu potpunu kompatibilnost sa drajverima za MongoDB i omogu\u0107e kori\u0161\u0107enje FerretDB kao transparentne zamene za MongoDB. <\/p>\n

MongoDB zauzima mesto izme\u0111u brzih i skalabilnih sistema koji upravljaju podacima u formatu klju\u010d\/vrednost i relacijskih baza podataka, funkcionalnih i pogodnih za formulisanje upita. MongoDB podr\u017eava skladi\u0161tenje dokumenata u JSON-sli\u010dnom formatu, ima dovoljno fleksibilan jezik za formulisanje upita, mo\u017ee kreirati indekse za razli\u010dite skladi\u0161tene atribute, efikasno obezbe\u0111uje skladi\u0161tenje velikih binarnih objekata, podr\u017eava logovanje operacija izmene i dodavanja podataka u bazu podataka, mo\u017ee raditi prema paradigmi Map\/Reduce, podr\u017eava replikaciju i izgradnju otpornih konfiguracija. <\/p>\n
