Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025.
If you would like to use Python UDFs, create the UDFs prior to that date.
Existing Python UDFs will continue to function as normal. For more information, see the
blog post
Getting the JDBC URL
Before you can connect to your Amazon Redshift cluster from a SQL client tool, you need to
know the JDBC URL of your cluster. The JDBC URL has the following format:
jdbc:redshift://.endpoint:port/database
The fields of the preceding format have the following values.
| Field | Value |
|---|---|
jdbc |
The protocol for the connection. |
redshift |
The subprotocol that specifies to use the Amazon Redshift driver to connect to the database. |
|
The endpoint of the Amazon Redshift cluster. |
|
The port number that you specified when you launched the cluster. If you have a firewall, make sure that this port is open for you to use. |
|
The database that you created for your cluster. |
The following is an example JDBC URL:
jdbc:redshift://examplecluster.abc123xyz789.us-west-2.redshift.amazonaws.com:5439/dev
If your URL values contain any of the following URI reserved characters, the values must be URL encoded:
-
;
-
+
-
{
-
}
-
[
-
]
-
&
-
=
-
?
-
an empty space
For example, if your PWD value is password:password, a
connection URL using that value would look something like the following:
jdbc:redshift://redshift.company.us-west-1.redshift.amazonaws.com:9000/dev;UID=amazon;PWD=password%3Apassword
For information about how to get your JDBC connection, see Finding your cluster connection string.
If the client computer fails to connect to the database, you can troubleshoot possible issues. For more information, see Troubleshooting connection issues in Amazon Redshift.
