Redshift query performance is set by distribution styles and sort keys — design decisions ordinary SQL tools keep invisible. DbSchema reverse-engineers the cluster into an ER diagram, lets you compare environments, and generates the sync script you read before it touches production.

A wrong distribution key means data shuffled between nodes on every join; a missing sort key means scans that should have been skips. These choices live in the DDL, and the query editor never shows them side by side with the relationships they serve.
DbSchema puts the whole warehouse on one canvas — tables, foreign-key relationships, and the layout decisions data engineers need to check against real join patterns.
From ad-hoc questions to governed schema promotion.
Assemble joins, WHERE conditions, and aggregations visually; the generated SQL runs on the cluster and the results come back inline — the Redshift console stays closed.
Compare the DDL state of two environments and get the ALTER and CREATE statements that close the gap — manual diffing out, reviewable scripts in.
Export browsable HTML with ER diagrams and table definitions, so report developers and auditors get an up-to-date reference without direct cluster access.
The Redshift schema lives in a design model file you keep in your repository — branch it, diff it, review it in a pull request. Approved changes become the ALTER and CREATE statements that move from the development cluster to production, one sign-off at a time.
Pick Amazon Redshift in the connection dialog and DbSchema downloads the JDBC driver
automatically. Supply the cluster endpoint, port 5439, database name, and
credentials — together they form
jdbc:redshift://cluster.region.redshift.amazonaws.com:5439/dbname. The
cluster's VPC security group must allow inbound TCP on 5439 from the machine running
DbSchema.
Redshift Serverless connects the same way with the workgroup endpoint in place of the
cluster endpoint — URL shape and port are unchanged. IAM authentication works through the
IAMAuth JDBC property. See the
Redshift JDBC driver page for the full setup.
