Redis tilbyder funktioner til at gemme data i n\u00f8gle\/v\u00e6rdi-format, udvidet med underst\u00f8ttelse af strukturerede dataformater som lister, hashes og s\u00e6t, samt muligheden for at udf\u00f8re server-side scripts i Lua. Projektets kode er skrevet i C og distribueres under AGPLv3-licensen.    <\/p>\n<p>Redis-databasen underst\u00f8tter transaktioner, der g\u00f8r det muligt at udf\u00f8re en gruppe kommandoer i \u00e9t trin og garanterer konsistens og sekvensering (andre foresp\u00f8rgsler kan ikke blande sig) i udf\u00f8relsen af det angivne kommando-s\u00e6t, og i tilf\u00e6lde af problemer tillades det at rulle \u00e6ndringer tilbage. Alle data caches i fuldt omfang i RAM. Klientbiblioteker er tilg\u00e6ngelige for de mest popul\u00e6re sprog, herunder Perl, Python, PHP, Java, Ruby og Tcl.     <\/p>\n<p>Til datah\u00e5ndtering gives der kommandoer som inkrement\/dekrement, standardoperationer p\u00e5 lister og s\u00e6t (forening, intersection), omd\u00f8bning af n\u00f8gler, multipel sampling og sorterede funktioner. To lagringsmetoder underst\u00f8ttes: periodisk synkronisering af data p\u00e5 disk og f\u00f8ring af en \u00e6ndringslog p\u00e5 disken. I det andet tilf\u00e6lde sikres det, at alle \u00e6ndringer bliver bevaret fuldt ud.
