La serie MariaDB 11.4 \u00e8 classificata come un rilascio con supporto a lungo termine e sar\u00e0 supportata per almeno 5 anni. Nel contempo, \u00e8 disponibile il rilascio MariaDB 11.5.1, che ha lo status di candidato al rilascio, e si \u00e8 formata la serie 11.6, nella quale sar\u00e0 sviluppata nuova funzionalit\u00e0.    <\/p>\n<p>Il progetto MariaDB sviluppa un fork di MySQL, mantenendo la compatibilit\u00e0 all'indietro e distinguendosi per l'integrazione di motori di archiviazione aggiuntivi e funzionalit\u00e0 avanzate. Lo sviluppo di MariaDB \u00e8 supervisionato dall'organizzazione indipendente MariaDB Foundation, secondo un processo di sviluppo aperto e trasparente, che non dipende da singoli fornitori. MariaDB \u00e8 fornito al posto di MySQL in molte distribuzioni Linux (RHEL, SUSE, Fedora, openSUSE, Slackware, OpenMandriva, ROSA, Arch Linux, Debian) ed \u00e8 implementato in grandi progetti come Wikipedia, Google Cloud SQL e Nimbuzz.       <\/p>\n<p>Tra le modifiche nella serie MariaDB 11.4 rispetto all'ultimo rilascio LTS 10.11:  <\/p>\n<ul>\n<li class=\"l\"> \u00c8 stato notevolmente migliorato l'ottimizzatore delle query, trasferito a un nuovo modello di costi che offre una previsione pi\u00f9 accurata del peso di ciascun piano di esecuzione della query. Il modello precedentemente utilizzato si adattava bene alla ricerca dell'indice ottimale, ma presentava problemi di applicabilit\u00e0 per operazioni di scansione di tabelle, scansione di indici o selezioni per intervallo. Con il nuovo modello, questa carenza \u00e8 stata superata modificando il peso di base delle operazioni legate al motore di archiviazione. Ad esempio, per le operazioni di archiviazione, come la scansione sequenziale delle righe, ora si presume che i dati siano archiviati su un'unit\u00e0 SSD veloce. Inoltre, sono stati ottimizzati anche altri parametri di peso dell'ottimizzatore, il che ha consentito, ad esempio, di utilizzare indici per le operazioni \"ORDER BY\/GROUP BY\" nelle sottoselezioni e di accelerare la gestione di tabelle molto piccole.\n<li class=\"l\"> \u00c8 stata notevolmente accelerata l'elaborazione delle sottoquery nelle espressioni UPDATE e DELETE limitate a una singola tabella.\n<li class=\"l\"> \u00c8 stata garantita l'utilizzazione di indici nelle query in cui le funzioni DATE e YEAR vengono confrontate con una costante, ad esempio, \"SELECT * FROM t2 WHERE YEAR(a) = 2024\" o \"SELECT * FROM t2 WHERE DATE(a)\"<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=61324\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0432\u044b\u043f\u0443\u0441\u043a \u0421\u0423\u0411\u0414 MariaDB 11.4.2, \u043a\u043e\u0442\u043e\u0440\u044b\u0439 \u043e\u0442\u043c\u0435\u0447\u0435\u043d \u043a\u0430\u043a \u043f\u0435\u0440\u0432\u044b\u0439 \u0441\u0442\u0430\u0431\u0438\u043b\u044c\u043d\u044b\u0439 \u0440\u0435\u043b\u0438\u0437 \u0432\u0435\u0442\u043a\u0438 11.4. \u0412\u0435\u0442\u043a\u0430 MariaDB 11.4 \u043e\u0442\u043d\u0435\u0441\u0435\u043d\u0430 \u043a \u043a\u0430\u0442\u0435\u0433\u043e\u0440\u0438\u0438 \u0432\u044b\u043f\u0443\u0441\u043a\u043e\u0432 \u0441 \u0434\u043b\u0438\u0442\u0435\u043b\u044c\u043d\u044b\u043c \u0441\u0440\u043e\u043a\u043e\u043c \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u0438 \u0438 \u0431\u0443\u0434\u0435\u0442 \u0441\u043e\u043f\u0440\u043e\u0432\u043e\u0436\u0434\u0430\u0442\u044c\u0441\u044f \u043a\u0430\u043a \u043c\u0438\u043d\u0438\u043c\u0443\u043c 5 \u043b\u0435\u0442. \u041e\u0434\u043d\u043e\u0432\u0440\u0435\u043c\u0435\u043d\u043d\u043e \u0434\u043e\u0441\u0442\u0443\u043f\u0435\u043d \u0432\u044b\u043f\u0443\u0441\u043a MariaDB 11.5.1, \u0438\u043c\u0435\u044e\u0449\u0438\u0439 \u0441\u0442\u0430\u0442\u0443\u0441 \u043a\u0430\u043d\u0434\u0438\u0434\u0430\u0442\u0430 \u0432 \u0440\u0435\u043b\u0438\u0437\u044b, \u0438 \u0441\u0444\u043e\u0440\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u0430 \u0432\u0435\u0442\u043a\u0430 11.6, \u0432 \u043a\u043e\u0442\u043e\u0440\u043e\u0439 \u0431\u0443\u0434\u0435\u0442 \u0440\u0430\u0437\u0432\u0438\u0432\u0430\u0442\u044c\u0441\u044f \u043d\u043e\u0432\u0430\u044f \u0444\u0443\u043d\u043a\u0446\u0438\u043e\u043d\u0430\u043b\u044c\u043d\u043e\u0441\u0442\u044c. \u041f\u0440\u043e\u0435\u043a\u0442\u043e\u043c MariaDB \u0440\u0430\u0437\u0432\u0438\u0432\u0430\u0435\u0442\u0441\u044f \u043e\u0442\u0432\u0435\u0442\u0432\u043b\u0435\u043d\u0438\u0435 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-116388","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.1.1 -
