Advanced ID Stitcher Features
Advanced features for fine-grained control over identity stitching, including inclusion/exclusion rules and cardinality limits.
The Profiles ID Stitcher provides advanced features that give you fine-grained control over how identities are connected in your graph, helping you maintain data quality, prevent identity explosion, and enforce business rules about identity relationships.
Available features
This section describes the advanced features available in the Profiles ID Stitcher.
Inclusion/exclusion rules
You can define specific rules to control which nodes and edges are included in your ID graph using a warehouse table. These rules provide the highest precedence over any other filtering mechanisms.
Key capabilities
- Exclude or include specific identifiers (node control)
- Define specific connections between identifiers (edge control)
- Manage rules through CLI tools
- Handle conflicting rules with configurable priority settings
See ID Graph Inclusion/Exclusion Rules for more details.
Cardinality rules
Set maximum connection limits between different ID types to prevent over-connected identity graphs and maintain data quality.
Key capabilities
- Define directional limits (for example, each email connects to at most 1
user_id) - Prevent identity explosion from shared identifiers
- Maintain audit trail of violations
- Support incremental runs with consistent behavior
- Optimize performance through controlled graph size
See ID Graph Cardinality Rules for more details.
How these features work together
Both features integrate seamlessly with your Profiles pipeline:
- Input filters reduce data volume before graph processing.
- Cardinality rules enforce connection limits during graph building.
- Inclusion/exclusion rules provide final control over specific nodes and edges.
This layered approach ensures you have comprehensive control over your identity graph while maintaining optimal performance and data quality.
