Redis tilbyr funksjoner for lagring av data i n\u00f8kkel\/verdi-format, utvidet med st\u00f8tte for strukturerte dataformater som lister, hash og sett, samt muligheten til \u00e5 kj\u00f8re skripter p\u00e5 serversiden skrevet i Lua. Prosjektkoden er skrevet i C og distribueres under AGPLv3-lisensen.    <\/p>\n<p>Databasen Redis st\u00f8tter transaksjoner som lar deg utf\u00f8re en gruppe kommandoer i ett trinn, og garanterer konsistens og sekvens (kommandoer fra andre foresp\u00f8rsel kan ikke blande seg inn) i utf\u00f8relsen av et givent sett med kommandoer, samt tillater tilbaketrekking av endringer i tilfelle problemer. Alle data buffers i sin helhet i RAM. Klientbiblioteker er tilgjengelige for de fleste popul\u00e6re spr\u00e5k, inkludert Perl, Python, PHP, Java, Ruby og Tcl.     <\/p>\n<p>For databehandling tilbys kommandoer som inkrementering\/dekrementering, standardoperasjoner for lister og sett (forening, skj\u00e6ring), omd\u00f8ping av n\u00f8kler, flerfaglige utvalg og sorteringsfunksjoner. To lagringsmoduser st\u00f8ttes: periodisk synkronisering av data til disk og vedlikehold av en logger for endringer p\u00e5 disk. I det andre tilfellet garanteres full bevaring av alle endringer. Det er mulig \u00e5 organisere master-slave datamatching for flere <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/no\/server\/\"   title=\"servere\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1797\">servere<\/a>, utf\u00f8rt i ikke-blokkerende modus. Ogs\u00e5 tilgjengelig er meldingsvekslingsmodus \u00abpublisering\/abonnement\u00bb, der det opprettes en kanal som sender meldinger til abonnenter.      <\/p>\n<p>N\u00f8kkelendringer i Redis 8.4:   <\/p>\n<ul>\n<li class=\"l\"> Komen \u00abFT.HYBRID\u00bb ble lagt til med implementering av hybrid s\u00f8k, som kombinerer mulighetene for fulltekst- og vektors\u00f8k i en foresp\u00f8rsel, og tar hensyn til b\u00e5de direkte treff og semantisk n\u00e6rhet. St\u00f8tte for aggregering av resultater med syntaks som i kommandoen \u00abFT.AGGREGATE\u00bb er tilgjengelig.\n<li class=\"l\"> Gjennomstr\u00f8mningsevnen i typiske Redis-applikasjoner for caching er forbedret. For eksempel, med belastninger som inkluderer 10% skriveoperasjoner (SET) og 90% leseoperasjoner (GET) med lagring av strengverdier p\u00e5 1 KB, \u00f8kte gjennomstr\u00f8mningen med 30%.             <center><img decoding=\"async\" alt=\"Utgivelsen av databasen Redis 8.4\" src=\"\/wp-content\/uploads\/2025\/11\/8358ec3dfe4f458bded1a72df61f9a88.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> Yttra til s\u00f8k (FT.SEARCH) og aggregering av resultater (FT.AGGREGATE) har blitt forbedret. I belastede systemer med et h\u00f8yt antall parallelle foresp\u00f8rselene er det registrert \u00f8kning i b\u00e5ndbredde og reduksjon i latens med opptil 4,7 ganger under s\u00f8k og opptil 1,4 ganger under aggregasjon av resultater.    <center><img decoding=\"async\" alt=\"Utgivelsen av databasen Redis 8.4\" src=\"\/wp-content\/uploads\/2025\/11\/262242ac34bc615c3ccdc0330dd7aacb.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>\n<li class=\"l\"> Optimalisering av minneallokering under foresp\u00f8rselene er gjennomf\u00f8rt, og det er n\u00e5 mulig \u00e5 tilpasse oppf\u00f8rselen ved utt\u00f8mming av tilgjengelig minne (OOM, out-of-memory).\n<li class=\"l\"> Minneforbruket har blitt redusert ved lagring av sm\u00e5 strenger (opptil 7 byte) i JSON-strukturer. For eksempel, et JSON-array med 500 sm\u00e5 elementer i n\u00f8kkel\/verdi-format bruker n\u00e5 37 % mindre minne.\n<li class=\"l\"> Effektiviteten ved lagring av numeriske JSON-arrayer, der alle elementene har samme type, har blitt forbedret (tidligere ble b\u00e5de type og verdi lagret for hvert element, mens n\u00e5 typen lagres \u00e9n gang for hele arrayet). I tester har slike arrayer med en million homogene elementer n\u00e5 et minnebehov som er 50-92 % lavere, avhengig av type.\n<li class=\"l\"> Kommandoen SET har f\u00e5tt alternativene IFEQ, IFNE, IFDEQ og IFDNE, som tillater \u00e5 oppdatere en strengen\u00f8kkel med kun \u00e9n kommando i situasjoner der tilknyttede verdier ikke er endret av en annen klient siden de ble hentet.\n<li class=\"l\"> Kommandoen XDELEX har blitt lagt til for atomisk sletting av en strengen\u00f8kkel hvis den tilknyttede verdien ikke har blitt endret siden den ble hentet.\n<li class=\"l\"> Kommandoen DIGEST er lagt til, som returnerer en hash av verdien knyttet til den angitte n\u00f8kkelen.\n<li class=\"l\"> I XREADGROUP-kommandoen er det lagt til alternativet \u00abCLAIM \u00bb for \u00e5 lese b\u00e5de ventende (idle pending) og innkommende (incoming) meldinger.\n<li class=\"l\"> Kommandoen MSETEX er lagt til for atomisk oppsett eller oppdatering av flere strengen\u00f8kler samtidig, samt oppdatering av levetiden deres.\n<li class=\"l\"> Det er lagt til en mekanisme for atomisk migrasjon av slotter mellom noder i klyngen (ASM \u2014 Atomic Slot Migration), som ligner p\u00e5 full synkron replikasjon, men som fungerer p\u00e5 niv\u00e5et av individuelle datalager-slotter. Komen CLUSTER MIGRATION er lagt til, som gj\u00f8r det mulig \u00e5 importere slotter fra andre noder, spore migrasjonsprogresjonen, og hvis n\u00f8dvendig, merke ventende migrasjonsoperasjoner.\n<li class=\"l\"> Team CLUSTER SLOT-STATS has been added for evaluating statistics in the cluster for individual slots, such as the number of keys, CPU load, and network I\/O.        <\/ul>\n<p>Kilde: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64338\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 \u0421\u0423\u0411\u0414 Redis 8.4, \u043e\u0442\u043d\u043e\u0441\u044f\u0449\u0435\u0439\u0441\u044f \u043a \u043a\u043b\u0430\u0441\u0441\u0443 NoSQL-\u0441\u0438\u0441\u0442\u0435\u043c.
