Segment Overview

Segments let you define user cohorts sharing behavioral patterns or attributes (e.g., 2+ purchases in last 7 days, iOS female age 20–30) and instantly inspect scale and event flow. This is an operator/marketer oriented guide, not a low-level developer spec.

What You Can Do with Segments

Marketing targeting: core retained users, pre-first-purchase drop-offs
Funnel comparison: conversion and abandonment deltas by cohort
Product insight: trend shifts by attribute + action combination
Real-time QA: validate condition logic via immediate event table feedback

UI Layout Summary

Area	Description
Toolbar (top-left)	New Segment button + search (by name)
Left List (DataTable)	Name, created date, edit icon; row select updates right panel; edit opens drawer
Right Header	Selected segment name (or empty placeholder)
Metrics Cards (3)	(1) Events share vs all events (2) Unique users share (3) 30-day trend direction/change
Event Table	Filtered raw events (time, event name, user/session/device/platform/geo/demographics, parameter JSON)
Pagination	Bottom navigation (fixed page size 15)

Creation & Editing Model

Creation/editing happens in a right-side slide drawer (sheet):

New Segment → empty form + single base condition slot
Edit icon → prefilled drawer
Close (X) prompts a confirmation if unsaved changes exist

Condition Model Key Concepts

Term	Meaning	Example
Group	Top-level AND block	Group1 AND Group2
Single Condition	One event or attribute selection	`page_view`, `user.age`
OR Group	Alternate conditions in a disjunctive block	(page_view OR screen_view)
Event Parameter Condition	Key/value filter on selected event	page_view WHERE page="product"
Attribute Condition	User/device/date field comparison	user.country = KR AND device.category = mobile
