Au fost publicate primele versiuni ale proiectului Redka, destinat furniz\u0103rii unui protocol RESP \u0219i API compatibile cu SGBD-ul Redis, dar implementate deasupra bibliotecii SQLite. Folosirea SQLite permite, de asemenea, accesarea datelor prin intermediul limbajului SQL, de exemplu, pentru generarea de rapoarte sau analiza datelor. Este sus\u021binut\u0103 utilizarea tranzac\u021biilor ACID. Redka poate fi lansat sub forma server<\/a>, care accept\u0103 cereri prin re\u021bea, sau poate fi utilizat ca un modul pentru limbajul Go. Codul proiectului este scris \u00een limbajul Go \u0219i este distribuit sub licen\u021ba BSD. <\/p>\n

\u00cen prezent, Redka a ad\u0103ugat suport pentru tipuri de date pentru lucrul cu \u0219iruri de caractere \u0219i hash-uri, precum \u0219i comenzi pentru manipularea datelor de tip \u0219ir, chei, tranzac\u021bii \u0219i hash-uri. De exemplu, sunt disponibile comenzi pentru setarea \u0219i ob\u021binerea uneia sau mai multor valori de \u0219ir legate de o cheie, stabilirea timpului de via\u021b\u0103 al cheilor, incrementarea\/decrementarea valorilor, c\u0103utarea cheilor dup\u0103 un model, redenumirea cheilor, executarea unei serii de comenzi \u00een cadrul unei tranzac\u021bii, anularea tranzac\u021biei, lucrul cu c\u00e2mpuri \u00een hash-uri. <\/p>\n

\u00cen viitorul apropiat se preconizeaz\u0103 ad\u0103ugarea suportului pentru liste, colec\u021bii (sets) \u0219i colec\u021bii sortate. Pe termen lung, se a\u0219teapt\u0103 implementarea algoritmului HyperLogLog, posibilit\u0103\u021bi de manipulare a coordonatelor geografice \u0219i comenzi pentru interac\u021biunea utiliz\u00e2nd modelul publish\/subscribe. P\u00e2n\u0103 acum, nu este planificat\u0103 ad\u0103ugarea suportului pentru scripturi \u00een limbajul Lua, autentificare, ACL, watch\/unwatch \u0219i posibilitatea de a lucra \u00eentr-o server<\/a> multime de baze de date. Cu siguran\u021b\u0103 nu va fi implementat suportul pentru clustere (Redis Cluster) \u0219i monitorizare (Redis Sentinel). <\/p>\n

Testele de performan\u021b\u0103 utiliz\u00e2nd instrumentele din proiectul Redis au ar\u0103tat c\u0103 Redka este cu 2-6 ori mai lent dec\u00e2t Redis din cauza lipsei optimiz\u0103rilor specifice pentru stocarea datelor \u00een format cheie\/valoare. \u00cen particular, \u00een cadrul mediului de testare creat, Redis a demonstrat o performan\u021b\u0103 de 133 de mii de opera\u021bii SET pe secund\u0103 \u0219i 139 de mii de opera\u021bii GET pe secund\u0103, \u00een timp ce performan\u021ba Redka a fost de 30 de mii SET pe secund\u0103 \u0219i 63 de mii GET pe secund\u0103 \u00een situa\u021bia \u00een care baza de date era stocat\u0103 \u00een memoria RAM. Atunci c\u00e2nd baza de date era stocat\u0103 pe disc, performan\u021ba Redka a fost de 22 de mii de opera\u021bii SET pe secund\u0103 \u0219i 56 de mii GET pe secund\u0103.
