Why teams connect DuckDB and Mixpanel

Give Mixpanel the users, events, and records that live in DuckDB in real time, and sync the cohorts and scores Mixpanel computes back into DuckDB where your applications read them.

Mixpanel is a read-only source: Stacksync reads its data in real time and delivers it into DuckDB, so DuckDB always reflects the current state of Mixpanel — without exports, scripts, or schedulers.

A database holds the rows your business runs on: the users, events, orders, and records that every service reads and writes. Mixpanel is where people make sense of them, as dashboards, funnels, cohorts, and metrics. Moving the data from DuckDB into Mixpanel usually means a hand-built extract or a change-data-capture pipeline that breaks the moment a column is renamed, and reporting that always trails last night's load.

Common use cases

  • 01 Export raw Events and User Profiles into Postgres or a warehouse so product usage can be joined with CRM and billing data in SQL.
  • 02 Pull Cohort membership into an operational database to drive lifecycle email and in-app targeting from a single source.
  • 03 Push aggregates computed in DuckDB out to a CRM or business tools so analysis results reach operational systems.
  • 04 Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.

Common sync patterns

Where Mixpanel tracks product events: behavior onto stored records

Signup, usage, and lifecycle events captured in Mixpanel sync into DuckDB as rows, so applications and internal tools can read behavioral data next to the records they already keep.

Where Mixpanel builds cohorts or scores: results your services can read

Segments, cohorts, or scores computed in Mixpanel sync back into DuckDB, where the services that read from the database act on them at query speed without calling the analytics API.

Analytics on live operational data, minus the pipeline

The users, events, orders, and records stored in DuckDB land in Mixpanel as they change, so dashboards, funnels, and metrics run on current data instead of last night's extract.

What you can sync between DuckDB and Mixpanel

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

DuckDB objects Mixpanel objects How this pairing syncs
Attached databases Additional database files or external systems attached into one session for cross-source queries. Group Profiles Account or workspace-level records from Group Analytics; read to roll event data up to a company or org dimension. Attached databases is specific to DuckDB and Group Profiles to Mixpanel — each maps to any object or custom field on the other side.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Cohorts Saved user segments; membership pulled through the Engage/cohorts Query API to drive downstream lifecycle lists. Database files is specific to DuckDB and Cohorts to Mixpanel — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to organize tables in sync outputs. Funnels Multi-step conversion reports; the Query API returns computed conversion rates rather than raw event rows. Schemas is specific to DuckDB and Funnels to Mixpanel — each maps to any object or custom field on the other side.
Tables Columnar tables created via SQL; the destination for materialized sync data. Retention Return-usage reports read from the Query API as aggregated cohort tables, not row-level records. Tables is specific to DuckDB and Retention to Mixpanel — each maps to any object or custom field on the other side.
Views SQL views used to shape or filter data for downstream consumers. Segmentation Property-based event breakdowns from the Query API, returned as time-series aggregates for reporting. Views is specific to DuckDB and Segmentation to Mixpanel — each maps to any object or custom field on the other side.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Lookup Tables Dimension tables joined to events; capped at 100MB with 100 writes per 24h, so treated as reference data. External files (Parquet/CSV/JSON) is specific to DuckDB and Lookup Tables to Mixpanel — each maps to any object or custom field on the other side.

How changes propagate between DuckDB and Mixpanel

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

DuckDB Mixpanel Interval-based propagation

DetectionStacksync polls DuckDB for changes on an incremental schedule, reading only records changed since the previous pass. Polling or full re-reads.

DeliveryMixpanel does not accept inbound record writes, so this direction carries requests rather than records: Mixpanel's output flows back as field updates on the originating DuckDB records.

Mixpanel DuckDB Interval-based propagation

DetectionStacksync polls Mixpanel for changes on an incremental schedule, reading only records changed since the previous pass. Pull-based: the Raw Data Export API is polled over an event-time date window (from_date/to_date).

DeliveryEach detected change is applied to DuckDB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • DuckDB: No API rate limits; throughput is bounded by local compute and I/O.
  • Mixpanel: Raw Data Export API allows 60 queries/hour, 3/second, and up to 100 concurrent; the Query API allows 60/hour with 5 concurrent; exceeding limits returns a 429.
