Exasol

Exasol is the in-memory database built for analytics.

Sync overview

Output schema

Each Airbyte Stream becomes an Exasol table and each Airbyte Field becomes an Exasol column. Each Exasol table created by Airbyte will contain 3 columns:

• _AIRBYTE_AB_ID: a uuid assigned by Airbyte to each event that is processed. The column type in Exasol is VARCHAR(64).
• _AIRBYTE_DATA: a json blob representing with the event data. The column type in Exasol is VARCHAR(2000000).
• _AIRBYTE_EMITTED_AT: a timestamp representing when the event was pulled from the data source. The column type in Exasol is TIMESTAMP.

Features

The Exasol destination supports the following features:

Feature	Supported? (Yes/No)	Notes
Full Refresh Sync	Yes
Incremental - Append Sync	Yes
Incremental - Append + Deduped	No
Normalization	No
Namespaces	Yes
SSL connection	Yes	TLS
SSH Tunnel Support	No

Limitations

Maximum data size two million characters

Exasol does not have a special data type for storing data of arbitrary length or JSON. That's why this connector uses type VARCHAR(2000000) for storing Airbyte data.

Getting started

Requirements

To use the Exasol destination, you'll need Exasol database version 7.1 or above.

Network Access

Make sure your Exasol database can be accessed by Airbyte. If your database is within a VPC, you may need to allow access from the IP you're using to expose Airbyte.

Permissions

As Airbyte namespaces allow to store data into different schemas, there are different scenarios requiring different permissions assigned to the user account. The following table describes 4 scenarios regarding the login user and the destination user.

Login user	Destination user	Required permissions	Comment
DBA User	Any user	-
Regular user	Same user as login	Create, drop and write table, create session
Regular user	Any existing user	Create, drop and write ANY table, create session	Grants can be provided on a system level by DBA or by target user directly
Regular user	Not existing user	Create, drop and write ANY table, create user, create session	Grants should be provided on a system level by DBA

We highly recommend creating an Airbyte-specific user for this purpose.

Setup guide

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

• Host
• Port
• Fingerprint of the Exasol server's TLS certificate (if the database uses a self-signed certificate)
• Username
• Password
