Why teams connect Apache Cassandra and Auth0

Close the gap between your application data and your directory: Apache Cassandra and Auth0 share users, groups, and access in real time, in both directions.

Auth0 is the system of record for who people are and what they can reach: users, the groups they belong to, and the applications assigned to them. Apache Cassandra holds the operational data those same people show up in, whether an employee or member table that decides who should have an account at all, a customers list, or the rows an application checks before it authorizes an action. The two describe overlapping users and groups, and when a nightly export or a hand-run script is all that connects them, accounts lag joiners and leavers and the application authorizes against a stale picture of who has access.

Stacksync syncs Materialized Views, Secondary Indexes, User-Defined Types, Collections in Apache Cassandra with Resource Servers (APIs), Log Events, Users, Roles in Auth0 field by field, in real time, and in both directions. You decide which system owns which fields, with the directory holding credentials and group membership and the database holding the source list of people who should exist at all, and Stacksync keeps every copy consistent, resolving conflicts by rules you set. A person added to a table becomes an account within seconds, a departure disables one just as fast, and the directory's users and groups are always present in your tables as ordinary rows.

Common use cases

  • 01 Consolidate data from multiple keyspaces or clusters into one reporting store.
  • 02 Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.
  • 03 Sync Organizations and their Connections into a customer database so B2B account records stay aligned with Auth0 tenants.
  • 04 Two-way sync of Users, including user_metadata and app_metadata, with a Postgres database so internal tools read and update profiles in SQL while Auth0 stays the login source of truth.

Common sync patterns

Deprovision the moment the record changes

When someone is marked inactive or removed in Apache Cassandra, the matching account in Auth0 is disabled within seconds, closing the window between a departure and a login that still works.

Read users and groups as ordinary tables

Users, groups, and their memberships from Auth0 land in Apache Cassandra as rows your application and queries can join, so authorization checks and access reporting run against the database instead of the directory API.

Keep group and role membership aligned

A group or role change made in either system updates the other, so the entitlements an application enforces match what the directory grants.

What you can sync between Apache Cassandra and Auth0

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Apache Cassandra objects Auth0 objects How this pairing syncs
Counters Increment-only counter columns, usually read-only in syncs. Log Events Tenant events (logins, signups, failed logins, admin changes) from /api/v2/logs; read-only, streamed into a warehouse for security analytics. Counters is specific to Apache Cassandra and Log Events to Auth0 — each maps to any object or custom field on the other side.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Users Core identity records with profile fields plus user_metadata and app_metadata; synced two-way (create, update, delete) via /api/v2/users. Credentials are never returned. Keyspaces is specific to Apache Cassandra and Users to Auth0 — each maps to any object or custom field on the other side.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Roles RBAC role definitions and their permissions; synced with a database to audit which users hold which access, and assigned to Users from either side. Tables is specific to Apache Cassandra and Roles to Auth0 — each maps to any object or custom field on the other side.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Organizations B2B customer tenants under /api/v2/organizations; synced two-way with a CRM or customer database to keep account records aligned with Auth0 orgs. Partitions and Rows is specific to Apache Cassandra and Organizations to Auth0 — each maps to any object or custom field on the other side.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Organization Members Membership records linking Users to Organizations with roles; written to provision and deprovision access as accounts change. Materialized Views is specific to Apache Cassandra and Organization Members to Auth0 — each maps to any object or custom field on the other side.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Connections Identity-provider configs (database, social, enterprise SAML/OIDC); typically read out to inventory how each tenant authenticates. Secondary Indexes is specific to Apache Cassandra and Connections to Auth0 — each maps to any object or custom field on the other side.

How changes propagate between Apache Cassandra and Auth0

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Apache Cassandra Auth0 Sub-second propagation

DetectionChanges in Apache Cassandra are captured at the source via change data capture — no polling loop against its API. Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns.

DeliveryEach detected change is written to Auth0 through its API, with automatic retries and rate-limit backoff.

Auth0 Apache Cassandra Sub-second propagation

DetectionAuth0 notifies Stacksync of record changes through webhook events. Event Streams and Log Streams deliver near-real-time user.created/updated/deleted and tenant events to a custom webhook or Amazon EventBridge.

DeliveryEach detected change is written to Apache Cassandra through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apache Cassandra: No API quotas; throughput is governed by cluster capacity and consistency-level choices.
  • Auth0: Per-tenant limit of about 15 Management API requests/second (bursts to 50) on paid tenants; X-RateLimit-* headers and HTTP 429 signal throttling.
