PostHog to MySQL Integration

How Datrise loads PostHog into MySQL

Datrise syncs PostHog's events, persons, sessions, feature flags, cohorts, and insights into MySQL as a typed table per source entity. Flexible or custom fields land in JSON columns, and timestamps such as created, updated, and status changes are typed as DATETIME/TIMESTAMP.

Sync is incremental: Datrise uses a watermark on updated-at, applied with INSERT … ON DUPLICATE KEY UPDATE, so re-runs update only what changed. Optional RANGE partitioning by load date. MySQL collation matters for CRM text, so Datrise lands utf8mb4 to preserve emoji and non-Latin characters.

Ideal for operational reporting and app databases already standardized on MySQL.

Endpoints

PostHog: Product analytics with session replay and flags.

MySQL: Widely used OSS relational engine (InnoDB).

How PostHog entities map to MySQL

PostHog entity	MySQL object	Notes
events	`posthog_events`	DATETIME/TIMESTAMP events
persons	`posthog_persons`	id PK · linked to posthog_events
sessions	`posthog_sessions`	id PK · linked to posthog_events
feature flags	`posthog_feature_flags`	id PK · linked to posthog_events

FAQ

How does Datrise handle PostHog's custom fields in MySQL?

Flexible values are stored as JSON columns, so new fields don't require a migration; strongly-typed fields — dates, numbers, and references — are promoted to native MySQL types.

How does the PostHog to MySQL sync stay up to date?

It runs incrementally — Datrise uses a watermark on updated-at, applied with INSERT … ON DUPLICATE KEY UPDATE.
