Getting started

Requirements

To use the MongoDB destination, you'll need:

• A MongoDB server

Setup guide

Permissions

You need a MongoDB user that can create collections and write documents. We highly recommend creating an Airbyte-specific user for this purpose.

Target Database

You will need to choose an existing database or create a new database that will be used to store synced data from Airbyte.

Setup the MongoDB destination in Airbyte

You should now have all the requirements needed to configure MongoDB as a destination in the UI. You'll need the following information to configure the MongoDB destination:

• Host
• Port
• Database
• Username
• Password

Notes about MongoDB Naming Conventions

From MongoDB Identifiers syntax:

Database Name Case Sensitivity

Since database names are case insensitive in MongoDB, database names cannot differ only by the case of the characters.

Restrictions on Database Names for Windows

For MongoDB deployments running on Windows, database names cannot contain any of the following characters: /. "$<>:|?

Also database names cannot contain the null character.

Restrictions on Database Names for Unix and Linux Systems

For MongoDB deployments running on Unix and Linux systems, database names cannot contain any of the following characters: /. "$

Also database names cannot contain the null character.

Length of Database Names

Database names cannot be empty and must have fewer than 64 characters.

Restriction on Collection Names

Collection names should begin with an underscore or a letter character, and cannot:

• contain the $.
• be an empty string (e.g. "").
• contain the null character.
• begin with the system. prefix. (Reserved for internal use.)
