In precedenza, affermavamo che l'ereditariet\u00e0 delle tabelle era la nostra implementazione del partizionamento, e questo \u00e8 vero. Tuttavia, questo metodo richiedeva di fare gran parte del lavoro manualmente. Ad esempio, se volevi che le tuple fossero inserite nelle sezioni durante gli INSERT, dovevi impostare i trigger per farlo per te.

This new algorithm can identify suitable partitions by examining the query condition <code>DOVE<\/code>. The previous algorithm, on the other hand, checked each partition to determine if it could meet the condition <code>DOVE<\/code>. Questo ha portato a un aumento del tempo di pianificazione man mano che cresceva il numero di sezioni.<\/p>\n<p>Con la versione 9.6, utilizzando la partizione tramite ereditariet\u00e0, l'instradamento delle tuple nelle sezioni avveniva di solito scrivendo una funzione trigger che conteneva una serie di operatori IF per inserire la tupla nella sezione corretta. Queste funzioni potevano essere molto lente nell'esecuzione. Con la partizione dichiarativa introdotta nella versione 10, questo \u00e8 diventato molto pi\u00f9 veloce.<\/p>\n<p>Utilizzando una tabella partizionata con 100 sezioni, possiamo valutare le prestazioni di caricamento di 10 milioni di righe in una tabella con 1 colonna BIGINT e 5 colonne INT.<\/p>\n<p><img decoding=\"async\" alt=\"PostgreSQL 11: L&#039;evoluzione del partizionamento da Postgres 9.6 a Postgres 11\" src=\"\/wp-content\/uploads\/2019\/05\/02c33ba997f187890046215997a689fc.png\" style=\"display:block;margin: 0 auto;\" \/><br \/>\n<br \/>\nLe prestazioni della query su questa tabella per cercare un singolo record indicizzato ed eseguire DML per manipolare un record (utilizzando solo 1 processore):<\/p>\n<p><img decoding=\"async\" alt=\"PostgreSQL 11: L&#039;evoluzione del partizionamento da Postgres 9.6 a Postgres 11\" src=\"\/wp-content\/uploads\/2019\/05\/8e69519dd97c6f2e60112908418e5c97.png\" style=\"display:block;margin: 0 auto;\" \/><br \/>\n<br \/>\nQui vediamo che le prestazioni di ogni operazione sono aumentate notevolmente dopo PG 9.6.
