A segment is a definition of a subpopulation, like a certain cohort of users.
A segment has no targeting key. Use segments with all targeting keys.

Segment Components

Segments consist of:
  • Inclusion criteria: Filters that describe which users belong to the segment
  • Allocation: The percentage of users matching the criteria to include
  • Exclusivity: Optional setting to make segments mutually exclusive
Segments are reusable across multiple flags and experiments, making them a powerful tool for consistent targeting across your feature flag infrastructure.
