Segment event producer for subscription developers

This project has been built for helping companies to create Segment connectors using subscriptions API (webhook). It allows to send a high volume of identity/group/alias/track/page/screen calls.

Segment subscriptions are documented here: https://segment.com/docs/partners/subscriptions/build-webhook/.

For load testing, just increase the concurrency and requests arguments.

Overview of event definition

Payload

• API schema v2
• 42k different identities (1 userId + 5 anonymousIds)
• 50 property names
• 200 event names
• 100 screen names
• 100% random URLs
• 50% calls don't have userId
• 20% calls don't have anonymousId
• replay always false
• sentAt < receivedAt < timestamp

During execution, properties sent into identify, group, track, page and screen calls will always have the same data type (number, string, datetime, boolean, object, array).

Ratio of calls per type

• 20% identify
• 5% group
• 5% alias
• 15% track
• 30% page
• 25% screen

Events will be triggered in a random order, and will be emitted from random users.
