Data profiling for Amazon S3 objects

Data profiling for
Amazon S3
 objects

Configure data profiling to run profiles on the metadata extracted from an
Amazon S3
 source system. You can view the profiling statistics in
Data Governance and Catalog
.
You can run data profiles on the following objects:
  • Avro
  • CSV
  • JSON
  • Parquet
To run profiles on Avro, JSON, or Parquet files, connect to an advanced cluster.
For more information about advanced clusters, see
Advanced Clusters
 in the Cloud Common Services help.
You can also run profiles on a Secure Agent installed on an Amazon EC2 instance on AWS that uses the Instance Metadata Service Version 2 (IMDSv2) method.
The data profiling task runs profiles on the following data types for Avro, CSV, JSON, and Parquet file formats:
