Couchbase

This page contains the setup guide and reference information for the Couchbase destination connector.

Overview

The Couchbase destination connector allows you to sync data to Couchbase, a distributed NoSQL database. Each stream is written to a collection in Couchbase, with support for both local clusters and Couchbase Capella (cloud service).

Output schema

Each stream will be output into a collection in Couchbase. The connector follows these rules for data mapping:

• Each record is stored as a JSON document in Couchbase
• Stream name is used as the collection name (sanitized to comply with Couchbase naming rules)
• Each document contains:
  • id: A unique identifier (UUID or composite key for deduplication)
  • type: Set to "airbyte_record"
  • stream: The source stream name
  • data: The actual record data

Performance considerations

• The connector uses batch operations for better performance
• Primary indexes are automatically created for each collection
• For large datasets, consider using incremental sync modes
• Adjust the batch size if needed (default: 1000 documents)

Supported sync modes

Sync mode	Supported?
Full Refresh - Overwrite	Yes
Full Refresh - Append	Yes
Full Refresh - Overwrite + Deduped	Yes
Incremental Sync - Append	Yes
Incremental Sync - Append + Deduped	Yes

Getting started

3. Username and password with appropriate permissions:
   • Data Reader (data_reader)
   • Data Writer (data_writer)
   • Query Manager (query_manage_index)

For Capella (Cloud)

1. A Couchbase Capella account
2. Database access credentials:
   • Database username
   • Database password
3. A bucket created in your Capella cluster
4. Allow list the IP addresses that Airbyte will connect from

Setup guide

Local Cluster Setup

1. Install Couchbase Server

   • Download and install Couchbase Server Community or Enterprise
   • Follow the installation wizard for your platform
   • Access the web console at http://localhost:8091

2. Create Resources

   • In the Couchbase Web Console, go to "Buckets" and click "Add Bucket"

     • Name: mybucket
     • Memory Quota: Set appropriate size (e.g. 100 MB)
     • Bucket Type: Couchbase
     • Click "Add Bucket" to create

3. Configure in Airbyte

   • Connection String: Enter your Couchbase connection string (e.g. couchbase://localhost)
   • Username: Enter your database username (e.g. airbyte_user)
   • Password: Enter your database password (e.g. your_secure_password)
   • Bucket: Enter your bucket name (e.g. my_bucket)
   • Scope: Enter your scope name (defaults to _default)

Capella Setup

1. Create Capella Resources

   • Log in to Couchbase Capella
   • Create a new database or use an existing one
   • Create a bucket for your data

2. Create Database Credentials

   • In Capella, go to "Security → Database Access"
   • Click "Create Database Credential"
   • Save the username and password

3. Allow List IP Addresses

   • In Capella, go to "Security → Network Security"
   • Add the IP addresses that Airbyte will connect from
   • Get the IPs from Airbyte documentation

4. Get Connection Details

   • In Capella, go to "Connect"
   • Copy the connection string

5. Configure in Airbyte

   • Connection String: Your Capella connection string
   • Username: Database username
   • Password: Database password
   • Bucket: Your bucket name
   • Scope: _default (or your custom scope)

Connection Configuration
