De f\u00f8rste udgivelser af projektet Redka er offentliggjort, som har til form\u00e5l at levere et RESP-protokol og API, der er kompatible med Redis-database, men implementeret ovenp\u00e5 SQLite-biblioteket. Brug af SQLite muligg\u00f8r ogs\u00e5 adgang til data ved hj\u00e6lp af SQL-sprog, for eksempel til at generere rapporter eller analysere data. ACID-transaktioner underst\u00f8ttes. Redka kan k\u00f8re i form server<\/a>, der modtager netv\u00e6rksanmodninger, eller bruges som en modul til Go-sproget. Projektkoden er skrevet i Go-sproget og distribueres under BSD-licensen. <\/p>\n

I \u00f8jeblikket har Redka f\u00e5et tilf\u00f8jet underst\u00f8ttelse af typer til arbejde med strenge og hashes, samt kommandoer til manipulation af strengdata, n\u00f8gler, transaktioner og hashes. For eksempel er der tilg\u00e6ngelige kommandoer til at indstille og hente \u00e9n eller flere strengv\u00e6rdier knyttet til en n\u00f8gle, angive udl\u00f8bstid for n\u00f8gler, inkrementere\/dekrementere v\u00e6rdier, s\u00f8ge n\u00f8gler efter m\u00f8nster, omd\u00f8be n\u00f8gler, udf\u00f8re en serie kommandoer inden for en transaktion, annullere en transaktion, samt arbejde med felter i hashes. <\/p>\n

I den n\u00e6rmeste fremtid planl\u00e6gges det at tilf\u00f8je underst\u00f8ttelse af lister, s\u00e6t (sets) og sorterede s\u00e6t. P\u00e5 l\u00e6ngere sigt forventes det, at algoritmen HyperLogLog vil blive implementeret, sammen med muligheder for manipulation af geografiske koordinater og kommandoer til interaktion ved hj\u00e6lp af publish\/subscribe-modellen. Der er endnu ikke planlagt underst\u00f8ttelse af scripts i Lua, autentificering, ACL, watch\/unwatch og muligheden for at arbejde inden for en serveren<\/a> flere databaser. Underst\u00f8ttelse af klynger (Redis Cluster) og overv\u00e5gning (Redis Sentinel) vil bestemt ikke blive implementeret. <\/p>\n

Ydelsestestning ved hj\u00e6lp af v\u00e6rkt\u00f8jer fra Redis-projektet har vist, at Redka er 2-6 gange langsommere end Redis p\u00e5 grund af manglende specifikke optimeringer til lagring af data i n\u00f8gle\/v\u00e6rdi-format. I den oprettede testmilj\u00f8 viste Redis en ydelse p\u00e5 133.000 SET-operationer pr. sekund og 139.000 GET-operationer pr. sekund, mens Redkas ydelse var 30.000 SET-operationer pr. sekund og 63.000 GET-operationer pr. sekund, n\u00e5r databasen blev placeret i RAM. Ved lagring af databasen p\u00e5 disk var Redkas ydelse 22.000 SET-operationer pr. sekund og 56.000 GET-operationer pr. sekund.
