Title
(EN) SYSTEMS AND METHODS FOR HASH CHAIN MIGRATIONS
(FR) SYSTÈMES ET PROCÉDÉS DE MIGRATIONS DE CHAÎNE DE HACHAGE
Abstract
(EN)
A method for hash chain migration includes detecting a version update of an object that includes a hash chain that stores fields of the object. Sub chains are identified from the hash chain. Migration sub chains are generated from the plurality of sub chains using a plurality of processes. Container blocks are generated from the plurality of migration sub chains. A migration chain is generated from the plurality of container blocks. The object is accessed using the migration chain.
(FR)
La présente invention concerne un procédé de migration de chaîne de hachage consistant à détecter une mise à jour de version d'un objet qui comprend une chaîne de hachage qui stocke des champs de l'objet. Des sous-chaînes sont identifiées à partir de la chaîne de hachage. Des sous-chaînes de migration sont générées à partir de la pluralité de sous-chaînes au moyen d'une pluralité de processus. Des blocs de conteneur sont générés à partir de la pluralité de sous-chaînes de migration. Une chaîne de migration est générée à partir de la pluralité de blocs de conteneur. L'accès à l'objet se fait au moyen de la chaîne de migration.
