Why teams connect Materialize and Notion

Get the data locked inside Notion into Materialize as live tables, and send results back where Notion can use them, without writing a pipeline.

Whatever Notion is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Pages, Databases / Data sources, Properties, Blocks from Notion into tables in Materialize continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Materialize can also be written back into fields in Notion where the tool can use them.

Common use cases

  • 01 Two-way sync a Notion projects or tasks data source with a Postgres table so engineers work in SQL while the team edits Pages in Notion, mapping status, date, and assignee properties both ways.
  • 02 Push rows from a warehouse or another database into a Notion data source as Pages so ops and leadership read live metrics in a familiar Notion view.
  • 03 Bridge streaming sources and non-streaming destinations by materializing joins across both.
  • 04 Sync operational CRM or ERP data into Materialize so real-time views stay current without batch loads.

Common sync patterns

Analytics on Notion's data

Records and events from Notion land in Materialize as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine Notion's data with data from every other synced system to answer questions no single tool can.

Where Notion accepts updates: operational write-back

Segments, scores, or reference values computed in Materialize sync back onto records in Notion, putting analysis where the work happens.

What you can sync between Materialize and Notion

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.

Materialize objects Notion objects How this pairing syncs
Tables User-managed tables that accept INSERT/UPDATE/DELETE from sync pipelines. Formula and Rollup properties Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back. Tables is specific to Materialize and Formula and Rollup properties to Notion — each maps to any object or custom field on the other side.
Sources Ingestion points (Kafka, Postgres CDC, MySQL CDC, webhook) that feed external data into Materialize. Users Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API. Sources is specific to Materialize and Users to Notion — each maps to any object or custom field on the other side.
Materialized Views Incrementally maintained query results that syncs read as continuously up-to-date datasets. Comments Page and inline discussion threads; can be read and created, useful for surfacing Notion activity in another system. Materialized Views is specific to Materialize and Comments to Notion — each maps to any object or custom field on the other side.
Sinks Outbound connections that emit view changes to Kafka topics. Files and attachments File-property and file-block values. Notion-hosted URLs are temporary and expire, so files are re-fetched or copied at sync time. Sinks is specific to Materialize and Files and attachments to Notion — each maps to any object or custom field on the other side.
Indexes In-memory arrangements that make view reads fast for serving workloads. Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. Indexes is specific to Materialize and Pages to Notion — each maps to any object or custom field on the other side.
Clusters Compute pools that isolate ingestion, view maintenance, and serving. Databases / Data sources Collections of pages with a typed property schema. Since the 2025-09-03 API a database is a container holding one or more data sources; syncs target a specific data_source_id. Clusters is specific to Materialize and Databases / Data sources to Notion — each maps to any object or custom field on the other side.

How changes propagate between Materialize and Notion

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.

Materialize Notion Sub-second propagation

DetectionChanges in Materialize are captured at the source via change data capture — no polling loop against its API. SUBSCRIBE queries stream row-level changes of any view or table to the client.

DeliveryEach detected change is written to Notion through its API, with automatic retries and rate-limit backoff.

Notion Materialize Sub-second propagation

DetectionNotion notifies Stacksync of record changes through webhook events. Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created.

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

Rate-limit considerations
