Athena

Module athena

Important Capabilities

Capability	Status	Notes
Data Profiling	✅	Optionally enabled via configuration. Profiling uses sql queries on whole table which can be expensive operation.
Descriptions	✅	Enabled by default
Domains	✅	Supported via the domain config field
Platform Instance	✅	Enabled by default
Table-Level Lineage	✅	Supported for S3 tables

This plugin supports extracting the following metadata from Athena

• Tables, schemas etc.
• Lineage for S3 tables.
• Profiling when enabled.

CLI based Ingestion

Install the Plugin

pip install 'acryl-datahub[athena]'
