Le projet vise \u00e0 faciliter la migration des applications utilisant MongoDB vers PostgreSQL et \u00e0 fournir une pile logicielle enti\u00e8rement ouverte. Le code est \u00e9crit en Go et distribu\u00e9 sous la licence Apache 2.0.    <\/p>\n<p>Le programme fonctionne sous la forme d'un proxy, transposant les requ\u00eates vers MangoDB en requ\u00eates SQL vers PostgreSQL, utilisant PostgreSQL comme v\u00e9ritable stockage. Le projet est compatible avec les pilotes pour MongoDB, mais il est encore au stade de prototype et ne prend pas encore en charge les fonctionnalit\u00e9s avanc\u00e9es du protocole MongoDB, bien qu'il soit d\u00e9j\u00e0 adapt\u00e9 pour la migration d'applications simples.       <\/p>\n<p>Le besoin de se d\u00e9tourner de l'utilisation de MongoDB peut surgir en raison du passage du projet \u00e0 une licence non libre SSPL, qui est fond\u00e9e sur la licence AGPLv3, mais n'est pas ouverte, car elle comporte une exigence discriminatoire de livraison sous licence SSPL non seulement du code de l'application elle-m\u00eame, mais aussi des sources de tous les composants impliqu\u00e9s dans la fourniture de service cloud.      <\/p>\n<p>Rappelons que MongoDB occupe une niche entre des syst\u00e8mes rapides et \u00e9volutifs manipulant des donn\u00e9es au format cl\u00e9\/valeur, et des bases de donn\u00e9es relationnelles, fonctionnelles et pratiques pour formuler des requ\u00eates. MongoDB prend en charge le stockage de documents au format JSON-like, dispose d'un langage suffisamment flexible pour formuler des requ\u00eates, peut cr\u00e9er des index pour divers attributs stock\u00e9s, assure efficacement le stockage de grands objets binaires, prend en charge le journal des op\u00e9rations de modification et d'ajout de donn\u00e9es \u00e0 la DB, peut fonctionner selon le mod\u00e8le Map\/Reduce, prend en charge la r\u00e9plication et la cr\u00e9ation de configurations tol\u00e9rantes aux pannes.<br \/>\n<br \/>Source : <a content=\"nofollow\" rel=\"nofollow\"
