Apache Cloudberry 2.0.0 \u00e8 segnato come il primo rilascio del progetto dopo il trasferimento del codice alla comunit\u00e0 Apache. Il progetto \u00e8 attualmente in fase di incubazione Apache e sar\u00e0 spostato tra i progetti primari di Apache al termine della preparazione dell'infrastruttura e della documentazione.    <\/p>\n<p>Il database Cloudberry \u00e8 un'edizione distribuita dell'open database PostgreSQL, ottimizzata per l'esecuzione di query analitiche su grandi volumi di dati (Data Warehouse). Per l'elaborazione parallela dei dati viene utilizzata un'architettura massivamente parallela (MPP, massively parallel processing), che garantisce la scalabilit\u00e0 dello storage fino a dimensioni petabyte suddividendo i dati in segmenti e utilizzando un cluster per il loro stoccaggio e trattamento. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1783\">server<\/a>.     <\/p>\n<p>Tra i miglioramenti in Apache Cloudberry 2.0.0:  <\/p>\n<ul>\n<li class=\"l\"> \u00c8 stata effettuata la migrazione alla base di codice PostgreSQL 14 (Greenplum si basava su PostgreSQL 12).\n<li class=\"l\"> \u00c8 stata aggiunta la supporto per tabelle dinamiche, che consentono di aggiornare automaticamente i risultati delle query.
