Apache Cloudberry 2.0.0 er markeret som den f\u00f8rste udgave af projektet efter overdragelsen af koden til Apache-samfundet. Projektet er stadig i Apache-incubatoren og vil blive opgraderet til prim\u00e6re Apache-projekter, n\u00e5r infrastrukturen og de tilh\u00f8rende elementer er klar.    <\/p>\n<p>Cloudberry-databasen er en distribueret version af den \u00e5bne database PostgreSQL, der er optimeret til at udf\u00f8re analytiske foresp\u00f8rgsler p\u00e5 store datam\u00e6ngder (Data Warehouse). En massiv parallel behandlingsarkitektur (MPP) anvendes til parallel data behandling, hvilket giver mulighed for skalering af lageret op til petabyte-st\u00f8rrelser ved at opdele data i segmenter og benytte et cluster til opbevaring og behandling. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/\"   title=\"servere\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1783\">servere<\/a>.     <\/p>\n<p>Blandt forbedringerne i Apache Cloudberry 2.0.0:  <\/p>\n<ul>\n<li class=\"l\"> Overgangen til kodebasen PostgreSQL 14 er blevet gennemf\u00f8rt (Greenplum var baseret p\u00e5 PostgreSQL 12).\n<li class=\"l\"> Der er tilf\u00f8jet support til dynamiske tabeller, som automatisk kan opdatere foresp\u00f8rgselsresultater.
