Redshift
Overview
The Redshift source supports Full Refresh syncs. That is, every time a sync is run, Airbyte will copy all rows in the tables and columns you set up for replication into the destination in a new table.
This Redshift source connector is built on top of the source-jdbc code base and is configured to rely on JDBC 4.2 standard drivers provided by Amazon via Mulesoft here as described in Redshift documentation here.
Sync overview
Resulting schema
The Redshift source does not alter the schema present in your warehouse. Depending on the destination connected to this source, however, the schema may be altered. See the destination's documentation for more details.
Features
| Feature | Supported | Notes |
|---|---|---|
| Full Refresh Sync | Yes | |
| Incremental Sync | Yes | Cursor-based, using ORDER BY on a user-defined cursor column |
| Replicate Incremental Deletes | Not supported in Redshift | |
| Logical Replication (WAL) | Not supported in Redshift | |
| SSL Support | Yes | |
| SSH Tunnel Connection | No | |
| Namespaces | Yes | Enabled by default |
| Schema Selection | Yes | Multiple schemas may be used at one time. Keep empty to process all of existing schemas |
Incremental Sync
The Redshift source connector supports incremental syncs. To setup an incremental sync for a table in Redshift in the Airbyte UI, you must setup a user-defined cursor field such as an updated_at column. The connector relies on this column to know which records were updated since the last sync it ran. See the incremental sync docs for more information.
Defining a cursor field allows you to run incremental-append syncs. To run incremental-dedupe syncs, you'll need to tell the connector which column(s) to use as a primary key. See the incremental-dedupe sync docs for more information.
Getting started
Requirements
- Active Redshift cluster
- Allow connections from Airbyte to your Redshift cluster (if they exist in separate VPCs)
Setup guide
1. Make sure your cluster is active and accessible from the machine running Airbyte
This is dependent on your networking setup. The easiest way to verify if Airbyte is able to connect to your Redshift cluster is via the check connection tool in the UI. You can check AWS Redshift documentation with a tutorial on how to properly configure your cluster's access here
2. Fill up connection info
Next is to provide the necessary information on how to connect to your cluster such as the host whcih is part of the connection string or Endpoint accessible here without the port and database name (it typically includes the cluster-id, region and end with .redshift.amazonaws.com).
Encryption
All Redshift connections are encrypted using SSL
