Proposed workflow

Plan table mappings between Scaleway Postgres and Supabase

This is an evaluation scenario; connector and operation support require confirmation.

Starting eventA selected source table needs an operational replica, a reporting projection, or a migration copy.

  1. Choose actual tables in Scaleway Postgres and Supabase and compare their schemas and record types.

  2. Specify the primary/business key, type conversions, filter boundaries, relationship dependencies, and the source of each writable field.

  3. Plan two-way sync around connector support and your update rules; use a source-to-destination copy for read-only records. Keep source views, aggregate outputs, and writable base tables distinct.

What to verifyCounts reconcile within identical filters; updates preserve keys; precision, nulls, deletes, and schema changes follow the agreed mapping rules.

Record coverage to review

Use documented coverage where available. Catalog record types are starting points for review and do not confirm Stacksync support.

Prepare Scaleway Postgres and Supabase access

Set up both accounts before testing the mapping. Use test records where available, and identify the account administrator who can approve access and help resolve setup errors.

Prepare to go live

Record the fields each system can update, the first-load cutoff, both record IDs, the expected update delay, and who handles errors. Complete the tests before production before expanding to more records.

Use the Scaleway Postgres and Supabase planning worksheet to capture these decisions. Record the access owner in the worksheet and enter credentials only in the connection setup.

Compare integration approaches

Choose a method around one example record and the update your business needs. Define how the Scaleway Postgres source record should appear or trigger work in Supabase. Compare ongoing sync, a custom workflow, and a scheduled export against that requirement.

Stacksync managed sync

Best fit
Review compatibility with a Stacksync engineer using an example of the records and updates you need.
Operating responsibility
Fits ongoing record synchronization when the required operations are supported. Add workflow steps for approvals or business actions that go beyond copying fields.
Before you choose
Provide your table or object schemas and one example update; confirm the supported keys, fields, and direction.

Native vendor integration

Best fit
A vendor-built integration may fit if it supports your Scaleway Postgres and Supabase record types.
Operating responsibility
Can reduce setup for a supported workflow. You may need another method for records or business steps it does not cover.
Before you choose
First check whether either vendor offers this integration. If available, verify your record types, update direction, account tier, and related-record handling.

Custom API or workflow

Best fit
Consider when Scaleway Postgres and Supabase need a transformation, approval, or action outside a direct record sync.
Operating responsibility
Provides control over business steps; the team owns credentials, version changes, error queues, and reconciliation.
Before you choose
Verify endpoint permissions, pagination, quotas, duplicate detection, and failure recovery.

File or scheduled snapshot

Best fit
Consider for a one-time Scaleway Postgres / Supabase migration or a reporting need with an explicit freshness window.
Operating responsibility
Can simplify a bounded transfer; later changes and deletion history require another extraction or a separately designed incremental process.
Before you choose
Record the extraction cutoff, source IDs, encoding, date/number formats, and reconciliation totals.

Workflow scenarios and expected results

Plan table mappings between Scaleway Postgres and Supabase

This is an evaluation scenario; connector and operation support require confirmation.

Starting event: A selected source table needs an operational replica, a reporting projection, or a migration copy.

  1. Choose actual tables in Scaleway Postgres and Supabase and compare their schemas and record types.
  2. Specify the primary/business key, type conversions, filter boundaries, relationship dependencies, and the source of each writable field.
  3. Plan two-way sync around connector support and your update rules; use a source-to-destination copy for read-only records. Keep source views, aggregate outputs, and writable base tables distinct.

Expected result: Counts reconcile within identical filters; updates preserve keys; precision, nulls, deletes, and schema changes follow the agreed mapping rules.

If it fails: Compare current source state, key mapping, and destination constraints before retrying. Reconcile the backlog after any schema or permission change.

Initial load and acceptance testing

Keep both record IDs with the expected and actual result. Reconcile the same filters and time window in each system.

Direction and permissions

Test case

Bring an example source record and the intended destination operation to the compatibility review. Confirm the supported route before granting write access.

Expected result

Only an approved, supported direction and permitted fields are written.

Schema, keys, and reconciliation

Test case

Use an actual Scaleway Postgres and Supabase table. Compare key uniqueness, nulls, decimal precision, timezone conversions, and counts within identical filters.

Expected result

The process meets its agreed freshness target and reconciliation has no unexplained differences.

Failed updates, retries and recovery

Start with the failed record and the destination error, then inspect the source value, field requirements, and access.

A record type or update is unavailable

Investigate

Check the Scaleway Postgres and Supabase connector guides, account permissions, and any operations marked On Request.

Next action

Ask the integration team to confirm a supported way to handle that record. Verify whether it needs connector configuration or a separate workflow step.

Source and destination disagree after a retry

Investigate

Compare current source values, destination validation, identity mappings, and any side effects already completed.

Next action

Stacksync issue retry reads the current source state. Decide the intended state before retrying or reverting; reconcile downstream effects separately.

Read the Stacksync issues dashboard guide for retry and revert behavior.

Update timing and record limits
  • Measure initial-load and ongoing-change latency separately. Source detection, selected objects, account limits, and destination validation determine the observed delay.
  • Review write-back, deletion handling, update timing, and account limits with the integration team.
