Abstract: In accordance with an embodiment, described herein is a JSON schema generator that parses a JSON stream, determines a data type of each record of the JSON stream, and selects a corresponding record schema generation logic component based on the determined data type to build a record schema for that record. In building a record schema, each element in a record and each sub-element in one or more nested layers of the record can be examined, to determine their data types. A corresponding parser can be selected for each element and sub-element based on a determined data type to generate a schema node. The generated schema nodes can be joined together to create a record schema for the record. Each record schema can be dynamically merged together to create a schema for the JSON stream.
