Forken ble dannet etter at Redis 7.4 ble flyttet til en propriet\u00e6r lisens. I utgivelsen av Redis 8.0 ble koden tilbakef\u00f8rt til den frie AGPLv3-lisensen, men dette p\u00e5virket ikke utviklingen av Valkey-prosjektet. Valkey utvikles p\u00e5 en n\u00f8ytral plattform under beskyttelse av Linux Foundation, med deltakelse fra utviklere fra selskaper som Amazon, Google, Oracle, Ericsson og Snap. Prosjektkoden er skrevet p\u00e5 C og distribueres under BSD-lisens. Det st\u00f8tter drift p\u00e5 Linux, macOS, OpenBSD, NetBSD og FreeBSD.     <\/p>\n<p>Valkey-databasen og Redis tilbyr funksjoner for lagring av data i n\u00f8kkel\/verdi-format, utvidet med st\u00f8tte for strukturerte dataformater som lister, hasher og sett, samt muligheten for \u00e5 utf\u00f8re skript p\u00e5 server-siden. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/no\/server\/dts-los-angeles\/\"   title=\"serveren\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3986\">serveren<\/a> skriftbehandlere p\u00e5 Lua. Databasen lagres i minnet og synkroniseres med versjonen p\u00e5 disk eller reflekteres i endringsloggen p\u00e5 disk, noe som garanterer dataintegritet ved kriseoppsigelse. Transaksjoner, &#171;publisering\/abonnement&#187; modus, kommandoer for inkrement\/dekrement, operasjoner p\u00e5 lister og mengder (samling, skj\u00e6ring), omd\u00f8ping av n\u00f8kler, master-slave replikasjon, flere valg og sorteringsfunksjoner st\u00f8ttes.       <\/p>\n<p>I den nye versjonen:  <\/p>\n<ul>\n<li class=\"l\"> For \u00e5 overf\u00f8re data mellom noder i klyngen benyttes teknikken for atom\u00e6r migrasjon av lagringsplasser, der data overf\u00f8res ikke p\u00e5 niv\u00e5et av individuelle n\u00f8kler (en n\u00f8kkel av gangen), men p\u00e5 niv\u00e5et av atom\u00e6r flytting av 16384-byte lagringsplasser. Overf\u00f8ringen skjer ved hjelp av AOF-formatet, som tillater sending av individuelle elementer i samlinger i stedet for all data knyttet til en n\u00f8kkel. Denne tiln\u00e6rmingen \u00f8ker ytelsen betydelig, unng\u00e5r omdireksjoner og eliminerer forsinkelser som oppstod n\u00e5r klienten fikk tilgang til den overflyttede n\u00f8kkelen.\n<li class=\"l\"> Muligheten for \u00e5 bestemme en individuell levetid for forskjellige felt i hasher knyttet til en n\u00f8kkel er lagt til (tidligere ble levetiden knyttet til n\u00f8kkelen og omfattet alle felt samtidig). For \u00e5 administrere levetiden til data er nye kommandoer lagt til: HEXPIRE, HEXPIREAT, HEXPIRETIME, HGETEX, HPERSIST, HPEXPIRE, HPEXPIREAT, HPEXPIRETIME, HPTTL, HSETEX, og HTTL.\n<li class=\"l\"> Det er n\u00e5 mulig \u00e5 bruke et klyngeoppsett med nummererte databaser, hvor n\u00f8kkelrommet deles mellom flere forskjellige databaser (standard 16).\n<li class=\"l\"> Effektiviteten til store klynger er forbedret - en klynge best\u00e5ende av 2000 noder har demonstrert evnen til \u00e5 h\u00e5ndtere en milliard foresp\u00f8rsel per sekund.\n<li class=\"l\"> Optimalisering er lagt til som i enkelte situasjoner kan \u00f8ke gjennomstr\u00f8mningen med 40% ved \u00e5 forh\u00e5ndslaste grupperte (pipelining) kommandoer i minnet.\n<li class=\"l\"> Optimalisering er lagt til som i enkelte situasjoner kan \u00f8ke gjennomstr\u00f8mningen med 20% ved \u00e5 unng\u00e5 kopiering av data i minnet (zero copy) under behandling av store foresp\u00f8rslere.\n<li class=\"l\"> St\u00f8tte for Multipath TCP-teknologi er lagt til for \u00e5 muliggj\u00f8re levering av pakker samtidig gjennom flere ruter via forskjellige nettverksgrensesnitt knyttet til forskjellige IP-adresser.
