L'azienda CockroachDB ha annunciato un cambiamento nella propria politica di licenza, che prevede la cessazione della fornitura della versione Core del proprio DBMS e una significativa limitazione delle opzioni gratuite. Le modifiche saranno applicate a partire dal rilascio 24.3, previsto per novembre. Il codice di CockroachDB continuer\u00e0 ad essere disponibile, ma con una licenza che limita il suo utilizzo (modello 'codice disponibile'). Finora, l'azienda ha offerto due varianti di DBMS: il gratuito CockroachDB Core, che offre funzionalit\u00e0 di base, e il a pagamento CockroachDB Enterprise, che include funzionalit\u00e0 avanzate e ottimizzazioni legate alla resilienza, scalabilit\u00e0 e protezione delle informazioni. <\/p>\n
La fornitura della versione gratuita di CockroachDB Core viene ora interrotta e al suo posto per il dispiegamento di CockroachDB sui propri server<\/a> sono ora disponibili due nuove versioni Enterprise, che contengono tutte le funzionalit\u00e0 avanzate, ma hanno limitazioni nell'uso: la versione di prova CockroachDB Enterprise Trial, utilizzabile solo per 30 giorni, e la versione CockroachDB Enterprise Free, che non ha limiti temporali ma pu\u00f2 essere utilizzata solo da sviluppatori individuali, studenti e aziende con un fatturato inferiore a 10 milioni di dollari all'anno. <\/p>\n Questo \u00e8 il secondo passo di CockroachDB verso un modello di sviluppo chiuso. Inizialmente, questo DBMS era distribuito sotto licenza Apache 2.0, ma nel 2019 \u00e8 stato trasferito alla licenza Business Source License (BSL), che non \u00e8 libera a causa della discriminazione di alcune categorie di utenti. Il principio della licenza BSL \u00e8 che il codice delle funzionalit\u00e0 avanzate pu\u00f2 essere utilizzato gratuitamente per un certo periodo di tempo, a condizione che vengano rispettate ulteriori condizioni, per eludere le quali \u00e8 necessario acquistare una licenza commerciale. Nel caso di CockroachDB, la condizione aggiuntiva riguarda il divieto di vendita di versioni commerciali di CockroachDB realizzate sotto forma di servizi cloud. <\/p>\n Il DBMS CockroachDB \u00e8 progettato per creare archivi geograficamente distribuiti e orizzontalmente scalabili ad alta affidabilit\u00e0, caratterizzati da un'elevata resilienza e indipendenti dai guasti di dischi, nodi e centri di elaborazione dati<\/a>Inoltre, CockroachDB garantisce l'integrit\u00e0 delle transazioni ACID, offre la possibilit\u00e0 di utilizzare SQL per manipolare i dati, consente di apportare modifiche allo schema di memorizzazione in tempo reale, supporta indici e chiavi esterne, e supporta la replica automatica e il riequilibrio dello storage.
