What does Atlan crawl from Hightouch?

Atlan crawls and maps the following assets and properties from Hightouch. Atlan establishes comprehensive lineage between your data warehouse sources and operational business tools by parsing Hightouch metadata.

• Hightouch models
• Hightouch syncs
• Column-level lineage between source and target systems

Atlan's Hightouch connectivity creates lineage flows that show how data moves from your warehouse through Hightouch models and syncs to operational business tools.

Models

Models define and organize the data that gets queried from source systems.

Source property	Atlan property	Where in Atlan
name	name	asset profile and overview sidebar
description	description	asset profile and overview sidebar
createdAt	sourceCreatedAt	asset profile and properties sidebar
updatedAt	sourceUpdatedAt	asset profile and properties sidebar

Model Types

Atlan supports two Hightouch model types:

• SQL Editor: Models defined with custom SQL queries. Atlan parses the SQL to establish upstream lineage to source tables and columns.
• Table Selector: Models that point directly to source tables. Atlan establishes lineage to the referenced table.

Syncs

Syncs define how queried results from models are mapped to destination systems.

Source property	Atlan property	Where in Atlan
name	name	asset profile and overview sidebar
description	description	asset profile and overview sidebar
status	flowStatus	asset filter and overview sidebar
lastRunAt	flowRunId	overview sidebar
createdAt	sourceCreatedAt	asset profile and properties sidebar
updatedAt	sourceUpdatedAt	asset profile and properties sidebar

Sync Types

Atlan focuses on Object-type syncs, which map model data to destination objects. Field mapping configurations establish column-level lineage between source and target fields.

Lineage establishment

Atlan establishes comprehensive lineage by parsing Hightouch metadata:

Upstream lineage (source to model)

• SQL Models: Parses SQL queries to identify referenced tables, views, and columns
• Table Models: Directly links to referenced source tables
• Column-level: Establishes source columns to model columns relationships where possible

Downstream lineage (model to destination)

• Field Mappings: Interprets sync configuration to link model columns to destination fields
• Standard Mapping: Direct field-to-field relationships
• Template Mapping: Parses Liquid templating to identify referenced source fields
