Why teams connect Google AlloyDB and Notion

Mirror Notion's data into Google AlloyDB 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 Google AlloyDB.

Stacksync mirrors Properties, Blocks, Formula and Rollup properties, Users from Notion into Replication Slots, Databases, Schemas, Tables in Google AlloyDB 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 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.
  • 02 Sync a Notion content-calendar database with Jira or Linear by mapping status and date properties both directions.
  • 03 Consolidate SaaS data into AlloyDB and serve analytics from its columnar engine without a separate OLAP store.
  • 04 Migrate workloads from self-managed Postgres while keeping existing syncs pointed at a compatible endpoint.

Common sync patterns

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.

Read Notion with a query

Records from Notion are ordinary rows in Google AlloyDB; join them, index them, and use them in application logic without touching the vendor API.

Automate Notion from your codebase

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

What you can sync between Google AlloyDB 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.

Google AlloyDB objects Notion objects How this pairing syncs
Replication Slots Logical replication artifacts that back log-based change capture. 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. Replication Slots is specific to Google AlloyDB and Files and attachments to Notion — each maps to any object or custom field on the other side.
Databases Standard PostgreSQL databases within an AlloyDB cluster that syncs connect to. Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. Databases is specific to Google AlloyDB and Pages to Notion — each maps to any object or custom field on the other side.
Schemas Namespaces used to separate synced SaaS data from application tables. 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. Schemas is specific to Google AlloyDB and Databases / Data sources to Notion — each maps to any object or custom field on the other side.
Tables Primary read/write target for bi-directional sync with CRMs and other systems. Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. Tables is specific to Google AlloyDB and Properties to Notion — each maps to any object or custom field on the other side.
Views Curated projections used as read-only sync sources. Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. Views is specific to Google AlloyDB and Blocks to Notion — each maps to any object or custom field on the other side.
Materialized Views Precomputed aggregates refreshed and synced outward on a schedule. Formula and Rollup properties Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back. Materialized Views is specific to Google AlloyDB and Formula and Rollup properties to Notion — each maps to any object or custom field on the other side.

How changes propagate between Google AlloyDB 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.

Google AlloyDB Notion Sub-second propagation

DetectionChanges in Google AlloyDB are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication.

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

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

Rate-limit considerations

  • Google AlloyDB: No API-style rate limits; throughput is bounded by instance size.
  • Notion: Average of ~3 requests/second per integration with some bursts; 429 with a Retry-After header when exceeded. Payloads capped at 500 KB and 1000 block elements.
