Objavili smo prve izdanja projekta Redka, koji je usmjeren na pru\u017eanje RESP protokola i API-ja kompatibilnih s bazama podataka Redis, ali implementiranih na vrhu SQLite knji\u017enice. Kori\u0161tenje SQLite dodatno omogu\u0107ava pristup podacima pomo\u0107u SQL jezika, na primjer, za generiranje izvje\u0161taja ili analizu podataka. Podr\u017eava se kori\u0161tenje ACID transakcija. Redka se mo\u017ee pokretati u obliku stre\u017enika<\/a>, koji prihva\u0107a zahtjeve putem mre\u017ee, ili se mo\u017ee koristiti kao modul za Go jezik. Kod projekta je napisan na Go jeziku i distribuira se pod BSD licencom. <\/p>\n

Trenutno Redka podr\u017eava tipove za rad sa stringovima i hash-ovima, kao i komande za manipulaciju string podacima, klju\u010devima, transakcijama i hash-ovima. Na primjer, dostupne su komande za postavljanje i dobivanje jednog ili vi\u0161e povezanih string vrijednosti, odre\u0111ivanje vremena trajanja klju\u010deva, inkrementiranje\/dekrementiranje vrijednosti, pretra\u017eivanje klju\u010deva po obrascu, preimenovanje klju\u010deva, izvr\u0161avanje niza komandi unutar transakcije, otkazivanje transakcije i rad s poljima u hash-ovima. <\/p>\n

U bliskoj budu\u0107nosti planira se dodati podr\u0161ka za liste, kolekcije (sets) i sortirane kolekcije. U daljoj perspektivi o\u010dekuje se implementacija HyperLogLog algoritma, mogu\u0107nosti za manipulaciju geografskim koordinatama i komande za interakciju koriste\u0107i model objavi\/pretplati. Za sada se ne planira dodavanje podr\u0161ke za Lua skripte, autentifikaciju, ACL, watch\/unwatch i mogu\u0107nost rada u jednom stre\u017enikom<\/a> od vi\u0161e baza podataka. To\u010dno se ne\u0107e implementirati podr\u0161ka za klastere (Redis Cluster) i nadzor (Redis Sentinel). <\/p>\n

Testiranje performansi kori\u0161tenjem alata iz projekta Redis pokazalo je da Redka zaostaje 2-6 puta za Redisom zbog nedostatka specifi\u010dnih optimizacija za pohranu podataka u formatu klju\u010d\/vrijednost. Naime, u stvorenom testnom okru\u017eenju Redis je pokazao performansu od 133 tisu\u0107e SET operacija u sekundi i 139 tisu\u0107a GET operacija u sekundi, dok je performansa Redke iznosila 30 tisu\u0107a SET operacija u sekundi i 63 tisu\u0107e GET operacija u sekundi u situaciji kada je baza podataka bila smje\u0161tena u operativnoj memoriji. Kada je baza podataka bila pohranjena na disku, performansa Redke iznosila je 22 tisu\u0107e SET operacija u sekundi i 56 tisu\u0107a GET operacija u sekundi.
