Amazon Redshift

Overview

Amazon Redshift is a fully managed, petabyte-scale cloud data warehouse from AWS. It uses columnar storage and a massively parallel processing (MPP) architecture to run analytical queries across large datasets, and integrates with the broader AWS ecosystem such as S3, Glue, and Redshift Spectrum. Redshift was originally derived from PostgreSQL and remains compatible with the PostgreSQL wire protocol, so standard Postgres clients can talk to it.

Driver

Connection fields

Field Description
Host Redshift cluster endpoint, e.g. mycluster.abc123.us-east-1.redshift.amazonaws.com.
Port TCP port the cluster listens on. Redshift defaults to 5439.
Database Name of the database to connect to. New clusters default to dev.
User Authentication username.
Password Authentication password. Stored in the macOS Keychain.
SSL Mode One of disable, prefer, require, verify-ca, or verify-full. Redshift clusters typically require SSL.
Options Additional connection parameters as key1=val1&key2=val2.

All connections also support an optional SSH tunnel. Configure the bastion host, port, user, and private key file under the SSH section of the connection form. See SSH tunnels for details.

URI format

Instead of filling in each field individually, you can paste a connection URI into the Paste URI field. Arris parses the URI and populates all fields automatically. Paste the cluster endpoint AWS shows in the Redshift console.

text Connection URI
redshift://user:[email protected]:5439/dev?sslmode=require

SSL & TLS

Redshift uses the same five SSL modes as PostgreSQL. Because Redshift clusters generally enforce encryption, Arris defaults Redshift connections to require.

SSL Mode Behavior
disable Never use SSL. Not recommended for production.
prefer Use SSL if available, fall back to unencrypted.
require Always use SSL. Fail if the server does not support it.
verify-ca Require SSL and verify the server certificate against a CA.
verify-full Require SSL, verify the CA, and verify the server hostname matches the certificate.

Schema browser

Once connected, Arris fetches the full schema tree and organizes it into groups. The default schema filter is set to public, but you can add or remove schemas from the filter dropdown in the sidebar.

The schema tree displays the following object types, grouped by category:

Double-click any table, view, materialized view, or external table to open it in a new tab with browse mode.

Supported SQL commands

Command Notes
SELECT Query data with WHERE filters, JOINs, aggregates, and window functions.
INSERT Insert single or multiple rows.
UPDATE Update existing rows.
DELETE Delete rows.
CREATE / DROP Create and drop tables, views, and other schema objects.
