get_entity_records

Glue.Client.get_entity_records(**kwargs)

This API is used to query preview data from a given connection type or from a native Amazon S3 based Glue Data Catalog.

Returns records as an array of JSON blobs. Each record is formatted using Jackson JsonNode based on the field type defined by the DescribeEntity API.

Spark connectors generate schemas according to the same data type mapping as in the DescribeEntity API. Spark connectors convert data to the appropriate data types matching the schema when returning rows.
