ScyllaDB keyspaces, mapped in minutes

See ScyllaDB Keyspaces and Partition Keys on One Canvas

DbSchema connects to ScyllaDB with a Cassandra-compatible JDBC driver, draws every keyspace as an ER diagram with partition and clustering keys annotated, and publishes documentation the whole team can browse.

  • Keyspaces, tables, and materialized views on one navigable diagram
  • Partition keys and clustering columns annotated right on the tables
  • Build CQL SELECT statements that respect partition key requirements
  • Share HTML docs covering replication settings and index structures

Partition Keys Rule ScyllaDB
cqlsh Shows Them One Table at a Time

ScyllaDB's shard-per-core architecture rewards a data model designed around its partition keys — and punishes one that isn't. Yet the only view most teams have of that model is DESCRIBE output in cqlsh, scrolled through table by table.

DbSchema reads the system catalog and lays the whole keyspace out visually: tables with their partition and clustering keys, materialized views, secondary indexes, and the full CQL type system — collections, frozen types, and user-defined types included.

Map, Query & Design
ScyllaDB Keyspaces Visually

Cassandra-compatible tooling for clusters that outgrew guesswork.

Reverse engineer a ScyllaDB keyspace into an ER diagram
A Diagram of Every Keyspace

Connect to a self-managed cluster or ScyllaDB Cloud and DbSchema reads the catalog — tables, column types, materialized views, and secondary indexes — into a diagram you can rearrange and annotate.

Build CQL queries for ScyllaDB visually
CQL Queries That Hit the Partition

Compose SELECT statements in the visual builder with partition key predicates in place, and skip the ALLOW FILTERING penalty that unqualified queries pay at runtime.

Organize ScyllaDB tables into focused diagrams
Layouts That Match Your Domains

Split a large keyspace into focused diagrams per domain, color-code the groups, and export to PDF or SVG when the data model goes into a design review.

Cluster Documentation
Without Cluster Access

One click renders the model as interactive HTML5 documentation: searchable diagrams, table definitions with partition and clustering key designations, keyspace replication strategy settings, and materialized view definitions. Teams running ScyllaDB across multiple datacenters get a shared reference nobody needs cqlsh — or cluster credentials — to read.

ScyllaDB Connection Facts — Driver, Port, URL

DbSchema ships its own open-source ScyllaDB JDBC driver — browse the code on GitHub — and the DataStax Cassandra JDBC driver works identically, since ScyllaDB is protocol-compatible with Apache Cassandra. Connect with the host, the keyspace, and port 9042 by default, giving a URL like jdbc:cassandra://host:9042/keyspace. If the cluster uses CQL authentication — Cassandra's PasswordAuthenticator — supply the username and password.

For ScyllaDB Cloud, use the hostname and credentials shown in the ScyllaDB Cloud console. Self-managed clusters with client-to-node encryption enabled take their SSL parameters in the JDBC URL or in the driver settings. Setup details are on the ScyllaDB JDBC driver page.
