De f\u00f6rsta utg\u00e5vorna av projektet Redka har offentliggjorts, som syftar till att tillhandah\u00e5lla RESP-protokollet och API:er som \u00e4r kompatibla med databashanteringssystemet Redis, men implementerade ovanp\u00e5 SQLite-biblioteket. Anv\u00e4ndningen av SQLite g\u00f6r det ocks\u00e5 m\u00f6jligt att komma \u00e5t data med hj\u00e4lp av SQL, till exempel f\u00f6r att skapa rapporter eller analysera data.

Projektkoden \u00e4r skriven i Go och distribueras under BSD-licensen. <\/p>\n

F\u00f6r n\u00e4rvarande har Redka lagt till st\u00f6d f\u00f6r typer f\u00f6r att arbeta med str\u00e4ngar och hash, liksom kommandon f\u00f6r att manipulera str\u00e4ngdata, nycklar, transaktioner och hash. Till exempel finns det kommandon f\u00f6r att st\u00e4lla in och h\u00e4mta ett eller flera str\u00e4ngv\u00e4rden kopplade till en nyckel, s\u00e4tta livsl\u00e4ngden f\u00f6r nycklar, \u00f6ka\/minska v\u00e4rden, s\u00f6ka nycklar med m\u00f6nster, byta namn p\u00e5 nycklar, utf\u00f6ra en serie kommandon inom ramen f\u00f6r en transaktion, avbryta en transaktion och arbeta med f\u00e4lt i hash. <\/p>\n

Inom en snar framtid planeras st\u00f6d f\u00f6r listor, samlingar (sets) och sorterade samlingar. P\u00e5 l\u00e4ngre sikt f\u00f6rv\u00e4ntas implementeringen av algoritmen HyperLogLog, m\u00f6jligheter f\u00f6r manipulation av geografiska koordinater och kommandon f\u00f6r interaktion med hj\u00e4lp av publicera\/prenumerera-modellen. F\u00f6r n\u00e4rvarande planeras det inte att l\u00e4gga till st\u00f6d f\u00f6r Lua-skript, autentisering, ACL, watch\/unwatch, och m\u00f6jligheten att arbeta med flera servern<\/a> databaser. St\u00f6d f\u00f6r kluster (Redis Cluster) och \u00f6vervakning (Redis Sentinel) kommer med s\u00e4kerhet inte att implementeras. <\/p>\n

Prestandatester med hj\u00e4lp av verktyg fr\u00e5n Redis-projektet har visat att Redka ligger 2-6 g\u00e5nger efter Redis p\u00e5 grund av bristen p\u00e5 specifika optimeringar f\u00f6r att lagra data i nyckel\/v\u00e4rde-format. I synnerhet visade Redis en prestanda p\u00e5 133 000 SET-operationer per sekund och 139 000 GET-operationer per sekund under de skapade testf\u00f6rh\u00e5llandena, medan redka prestanda var 30 000 SET per sekund och 63 000 GET per sekund n\u00e4r databasen lagrades i RAM. N\u00e4r databasen lagrades p\u00e5 disk var prestanda f\u00f6r Redka 22 000 SET-operationer per sekund och 56 000 GET-operationer per sekund.
