Managing Profilers

The Cloudera Data Catalog profiler engine runs data profiling operations on data located in multiple data lakes. These profilers create metadata annotations that summarize the content and shape characteristics of the data assets.

Table 1. List of built-in profilers
Profiler Name in VM-based environments	Profiler Name in Compute Cluster enabled environments	Description
Cluster Sensitivity Profiler	Data Compliance	A sensitive data profiler- PII, PCI, HIPAA, etc.
Ranger Audit Profiler	Activity Profiler	A Ranger audit log summarizer.
Hive Column Profiler	Statistics Collector	Provides summary statistics like Maximum, Minimum, Mean, Unique, and Null values at the Hive column level.

Limitations

In VM-based environments, profilers do not support Iceberg tables. However, Iceberg tables are discoverable. In Compute Cluster enabled environments, Iceberg tables can be profiled.
In Compute Cluster enabled environments, profilers only support tables which are stored on AWS S3 storage.
Supported file formats:
- VM-based environments:
  - CSV
- Compute Cluster enabled environments:
  - Statistics Collector profilers and Data Compliance profilers
    - CSV
    - Parquet
    - Iceberg tables
    - ORC
