Cloudflare har publicerat k\u00e4llkoden f\u00f6r sin egen version av proxyservern PgBouncer, som anv\u00e4nds f\u00f6r att uppr\u00e4tth\u00e5lla en pool av \u00f6ppna anslutningar till databashanteraren PostgreSQL. PgBouncer m\u00f6jligg\u00f6r f\u00f6r applikationer att kommunicera med PostgreSQL genom redan etablerade anslutningar f\u00f6r att undvika resurskr\u00e4vande och upprepade operationer av att \u00f6ppna och st\u00e4nga anslutningar, samt minska antalet aktiva anslutningar till PostgreSQL. <\/p>\n

De f\u00f6reslagna \u00e4ndringarna i forken syftar till att uppn\u00e5 en striktare isolering av resurser p\u00e5 niv\u00e5erna f\u00f6r enskilda databaser (CPU-belastning, minnesanv\u00e4ndning och IO-intensitet) och att s\u00e4kerst\u00e4lla en begr\u00e4nsning av antalet anslutningar kopplade till anv\u00e4ndaren och anslutningspoolen. Till exempel har den publicerade forken implementerat en m\u00f6jlighet att begr\u00e4nsa storleken p\u00e5 anslutningspoolen f\u00f6r varje anv\u00e4ndare, vilket fungerar korrekt i konfigurationer med v\u00e4rdbaserad autentisering (HBA). Dessutom har st\u00f6d f\u00f6r dynamisk justering av begr\u00e4nsningar av antalet anslutningar fr\u00e5n varje anv\u00e4ndare lagts till, vilket m\u00f6jligg\u00f6r en mer flexibel begr\u00e4nsning av anv\u00e4ndare som skickar m\u00e5nga resurskr\u00e4vande f\u00f6rfr\u00e5gningar.
