Why teams connect Citus and Notion

Mirror Notion's data into Citus so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Notion through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Citus.

Stacksync mirrors Databases / Data sources, Properties, Blocks, Formula and Rollup properties from Notion into Views, Sequences, Distributed tables, Reference tables in Citus and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Notion, so the tool and the database never disagree.

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 Sync high-volume event or tenant data from a Citus cluster into a warehouse for cross-tenant analytics.
  • 04 Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.

Common sync patterns

Automate Notion from your codebase

Write to the synced tables in Citus and Stacksync propagates the change into Notion, replacing custom integration code.

React to changes as they happen

Updates in Notion arrive as row changes in Citus, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

What you can sync between Citus 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.

Citus objects Notion objects How this pairing syncs
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Users Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API. Local tables is specific to Citus and Users to Notion — each maps to any object or custom field on the other side.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Comments Page and inline discussion threads; can be read and created, useful for surfacing Notion activity in another system. Schemas is specific to Citus and Comments to Notion — each maps to any object or custom field on the other side.
Views Curated projections over distributed data, often used as read-only sync sources. 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. Views is specific to Citus and Files and attachments to Notion — each maps to any object or custom field on the other side.
Sequences Key generators that matter when external writes must not collide with application inserts. Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. Sequences is specific to Citus and Pages to Notion — each maps to any object or custom field on the other side.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. 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. Distributed tables is specific to Citus and Databases / Data sources to Notion — each maps to any object or custom field on the other side.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. Reference tables is specific to Citus and Properties to Notion — each maps to any object or custom field on the other side.

How changes propagate between Citus 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.

Citus Notion Sub-second propagation

DetectionChanges in Citus are captured at the source via change data capture — no polling loop against its API. PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres.

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

Notion Citus 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 Citus as a row-level write, with types converted between the two schemas.

Rate-limit considerations
