To add a database connection, click the grid icon in the top right, and navigate to Admin > Databases > Add a database.
Fill out the fields for that database, and click Save changes at the bottom.
You can edit these settings at any time. Just remember to save your changes.
Paste a connection string here to pre-fill the remaining fields below.
The display name for the database in the Metabase interface.
Your database's IP address, or its domain name (e.g., esc.mydatabase.com).
The database port. E.g., 8080.
Presto catalogs contain schemas and reference data sources via a connector.
Only add tables to Metabase that come from a specific schema.
The database username for the account that you want to use to connect to your database. You can set up multiple connections to the same database using different user accounts to connect to the same database, each with different sets of privileges.
The password for the username that you use to connect to the database.
Metabase automatically tries to connect to databases with SSL first, then without if that doesn't work. If it's possible to connect to your database with an SSL connection, Metabase will make that the default setting for your database. If you prefer to connect without this layer of security, you can always change this setting later, but we recommend keeping SSL turned on to keep your data secure.
Metabase supports both keystores and truststores.
You can specify a local file path, or upload a keystore. You'll also need to input your keystore password.
You can specify a local file path, or upload a truststore. You'll also need to input your truststore password.
Kerberos settings include:
- Kerberos principal (e.g.,
service/instance@REALM) - Kerberos coordinator service (e.g.,
presto) - You can use a canonical hostname.
- Kerberos credential cache file (e.g.,
/tmp/kerbo-credential-cache) - Kerberos keytab file (e.g.,
/path/to/kerberos.keytab) - Kerberos configuration file (e.g.,
/etc/krb5.conf) - Presto coordinator Kerberos service principal pattern (e.g.,
${SERVICE}@${HOST}.${SERVICE}
You can append options to the connection string that Metabase uses to connect to your database.
Turn this option OFF if people want to click Run (the play button) before applying any Summarize or filter selections.
By default, Metabase will execute a query as soon as you choose an grouping option from the Summarize menu or a filter condition from the drill-through menu. If your database is slow, you may want to disable re-running to avoid loading data on each click.
See syncs and scans.
Periodic refingerprinting will increase the load on your database.
Turn this option ON to scan a sample of values every time Metabase runs a sync.
A fingerprinting query examines the first 10,000 rows from each column and uses that data to guesstimate how many unique values each column has, what the minimum and maximum values are for numeric and timestamp columns, and so on. If you leave this option OFF, Metabase will only fingerprint your columns once during setup.
{% include plans-blockquote.html feature="Writeable connection" is_plural=true%}
Set up an additional connection used for write operations. See Writeable connections.
With database routing, an admin can build a question once using one database (data catalog), and the question will run its query against a different data catalog with the same schema depending on who is viewing the question.
