Projektet er stadig i Apache-inkubatoren og vil blive overf\u00f8rt 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\">servere<\/a>. <\/p>\n<p>Blandt forbedringerne i Apache Cloudberry 2.2.0:<\/p>\n<ul>\n<li class=\"l\"> Fejlrettelser, s\u00e5rbarhedsl\u00f8sninger og optimeringer fra PostgreSQL-versionerne 14.4-14.10 er blevet overf\u00f8rt (Cloudberry 2.x-grenen er bygget p\u00e5 PostgreSQL 14's kodedatabase).\n<li class=\"l\"> Seks udvidelser er tilf\u00f8jet: diskquota, gp_stats_collector, gp_relsizes_stats, reject_partition_fullscan, try_convert og yezzey.\n<li class=\"l\"> Udvidelsen interconnect er blevet tilf\u00f8jet, hvilket giver opsummerede t\u00e6llere fra UDPIFC-protokollen, der er tilg\u00e6ngelige via visningerne gp_interconnect_stats, gp_interconnect_stats_per_segment og gp_interconnect_stats_per_host.
