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 isVARCHAR(64)._AIRBYTE_DATA: a json blob representing with the event data. The column type in Exasol isVARCHAR(2000000)._AIRBYTE_EMITTED_AT: a timestamp representing when the event was pulled from the data source. The column type in Exasol isTIMESTAMP.
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
