Please see our Integrations page to browse our ingestion sources and filter on their features.

Integration Methods​

DataHub offers three methods for data ingestion:

Types of Integration​

Integration can be divided into two concepts based on the method:

  • Push-based integration
  • Pull-based integration

Push-based Integration​

Push-based integrations allow you to emit metadata directly from your data systems when metadata changes. Examples of push-based integrations include Airflow, Spark, Great Expectations and Protobuf Schemas. This allows you to get low-latency metadata integration from the "active" agents in your data ecosystem.

Pull-based Integration​

Pull-based integrations allow you to "crawl" or "ingest" metadata from the data systems by connecting to them and extracting metadata in a batch or incremental-batch manner. Examples of pull-based integrations include BigQuery, Snowflake, Looker, Tableau and many others.

Core Concepts​

The following are the core concepts related to ingestion:

  • Sources : Data systems from which extract metadata. (e.g. BigQuery, MySQL)
  • Sinks : Destination for metadata (e.g. File, DataHub)
  • Recipe : The main configuration for ingestion in the form or .yaml file
