Method and system for creating indices and loading key-value pairs for NoSQL databases
View Patent ↗Systems and methods are provided for creating indices and loading key-value pairs for NoSQL databases. Attributes are created that correspond to records in a NoSQL database based on corresponding record fields. An index is created based on the attributes. A memory is loaded with attributes that correspond to a subset of the index as keys in a key-value pair and identifiers that correspond to records that correspond to the attributes as values in the key-value pair. The attributes that correspond to the subset of the index are sorted in the memory. Any duplicate attributes are identified from the sorted attributes in the memory. Any identifiers that correspond to any duplicate attributes also identify records in the NoSQL database to be evaluated as potential duplicate records.
