Abstract
A system for updating a target schema of a graph model and methods for making and using same. A schema change job can be run to update the target schema. Loaded source data in the graph model can be updated based on the updated target schema. The schema can be changed at vertex type level, edge type level and attribute level for a pre-defined target schema after source data has been loaded. The loaded source data can be updated to be consistent with the updated target schema without a need of being reloaded. The schema change job can be defined declaratively. The target schema can be versioned and stored to maintain a history of target schema update. Advantageously, schema update can be easy to implement. The time-consuming and expensive reloading process can be avoided. Target schema updating can have high flexibility and high performance.
