Why teams connect Amazon Lightsail and DuckDB

Keep Amazon Lightsail and DuckDB synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between Amazon Lightsail and DuckDB continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • Push cleaned or enriched records from central systems back into the Lightsail database behind a small web app.
  • Migrate data continuously from a Lightsail database to a larger managed database as an application outgrows the VPS tier.
  • Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both Amazon Lightsail and DuckDB, so each workload runs on the engine that suits it.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

What you can sync between Amazon Lightsail and DuckDB

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.

Amazon Lightsail objects DuckDB objects
Databases Logical databases on the instance that scope a connection. Views SQL views used to shape or filter data for downstream consumers.
Schemas Namespaces used when selecting tables to sync. External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format.
Tables Relational tables read from and written to at row level. Attached databases Additional database files or external systems attached into one session for cross-source queries.
Views Query-backed read-only sources. Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage.
Users and Grants Database accounts used to give the sync connection scoped access. Schemas Namespaces within a database used to organize tables in sync outputs.
Managed Databases Lightsail-hosted MySQL or PostgreSQL instances that a sync connects to as standard databases. Tables Columnar tables created via SQL; the destination for materialized sync data.

How the Amazon Lightsail and DuckDB connectors work

Amazon Lightsail

Integration surface
MySQL or PostgreSQL wire protocol (SQL) to the managed database endpoint
Authentication
Database credentials; public endpoint access must be enabled or a tunnel used
Change detection
Polling on timestamp or key columns; log-based CDC depends on engine parameter access, which is more limited than on full RDS
Capabilities
read · write
Rate limits
No API-style rate limits; capacity is fixed by the chosen Lightsail bundle

DuckDB

Integration surface
In-process SQL engine via client libraries (Python, Node.js, JDBC, CLI); no server or network API by default
Authentication
None built in; access control is file-system level (MotherDuck adds token auth for its hosted service)
Change detection
Polling or full re-reads; no change feed or transaction log API
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by local compute and I/O
