Why teams connect ClickHouse and Okta

Land the users, groups, and access events from Okta in ClickHouse continuously for security analytics, and write computed results back — without building or maintaining a pipeline.

Okta is the record of who exists and what they can reach; ClickHouse is where the business measures everything else. The two overlap on people and their access — the same users, groups, roles, and events that Okta governs are what security, compliance, and analytics teams want to query in ClickHouse. Getting them there usually means a brittle export that runs overnight and hands auditors a snapshot that is already out of date.

Stacksync syncs Policies, System Log, Devices, Users from Okta into tables in ClickHouse in real time, and the connection works in both directions: values computed in ClickHouse, such as risk scores or access-review decisions, can be written back to attributes in Okta where the identity team acts on them. Schema changes are handled, API limits are managed, and the sync is something you configure rather than a pipeline you keep alive.

Common use cases

  • 01 Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • 02 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • 03 Read Application assignments and Factors into a database to report on who can reach which app and which users have strong MFA enrolled.
  • 04 Drive Group Rules and policy assignments from HR attributes so access changes the moment a title, department, or location changes.

Common sync patterns

Access governance on joined data

Join Okta's users and group memberships with HR, product, and usage data already in ClickHouse to surface who holds access they no longer need.

Queryable history for audit and compliance

A continuously synced copy in ClickHouse gives you a durable, queryable record of identity and access state for access reviews, SOC 2, and audit questions.

Risk and review results back on the account

Risk scores, anomaly flags, or access-review outcomes computed in ClickHouse write back to attributes on the matching user in Okta, where the identity team can act on them.

What you can sync between ClickHouse and Okta

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.

ClickHouse objects Okta objects How this pairing syncs
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Policies Sign-on, password, and authenticator-enrollment policies with their rules; read to audit access controls or updated to manage them centrally. Dictionaries is specific to ClickHouse and Policies to Okta — each maps to any object or custom field on the other side.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. System Log Immutable audit event stream of logins, admin changes, and lifecycle events; read-only, polled by timestamp and used as the change feed and SIEM source. Tables (MergeTree family) is specific to ClickHouse and System Log to Okta — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Devices Registered and managed device records tied to users; read to correlate access with device posture and to feed inventory or conditional-access reporting. Databases is specific to ClickHouse and Devices to Okta — each maps to any object or custom field on the other side.
Views Saved queries used as curated, read-only sync sources. Users Universal Directory user records with profile attributes, credentials, and lifecycle status (staged, active, suspended, deprovisioned); full CRUD, so users are created, updated, activated, and deactivated to match an HR or identity source. Views is specific to ClickHouse and Users to Okta — each maps to any object or custom field on the other side.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Groups Okta groups (OKTA_GROUP, APP_GROUP, BUILT_IN) and their memberships; OKTA_GROUP records and membership are written to drive app and resource access. Materialized views is specific to ClickHouse and Groups to Okta — each maps to any object or custom field on the other side.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Applications App integrations (SAML, OIDC, SWA) with per-user and per-group assignments; read and updated to manage which identities can reach each downstream app. Distributed tables is specific to ClickHouse and Applications to Okta — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse and Okta

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.

ClickHouse Okta Interval-based propagation

DetectionStacksync polls ClickHouse for changes on an incremental schedule, reading only records changed since the previous pass. No log-based CDC for consumers.

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

Okta ClickHouse Sub-second propagation

DetectionOkta notifies Stacksync of record changes through webhook events. Event Hooks send an HTTPS POST to a subscribed endpoint on events such as user.lifecycle.create and group.user_membership.add (after a one-time.

DeliveryEach detected change is applied to ClickHouse as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Okta: Rate limits are enforced per org, per endpoint group, per minute and vary by Okta edition; responses carry X-Rate-Limit-Limit, X-Rate-Limit-Remaining, and X-Rate-Limit-Reset headers and exceeding one returns HTTP 429. The System Log is more tightly limited (about 120 requests/minute) and a separate concurrent-request cap (default 75 in-flight transactions) also applies.

How the ClickHouse and Okta connectors work

ClickHouse

Integration surface
Native TCP protocol and HTTP interface; standard SQL dialect, with MySQL and PostgreSQL wire compatibility available
Authentication
Database credentials (username/password); ClickHouse Cloud issues per-service credentials over TLS
Change detection
No log-based CDC for consumers; incremental reads use polling on monotonic columns, and ClickHouse is usually the destination rather than the source
Capabilities
read · write

Okta

Integration surface
REST API (Okta Management API, /api/v1) with Event Hooks for outbound events and the System Log API as the change feed
Authentication
SSWS API tokens (Authorization: SSWS {token}) scoped to the creating admin's permissions, or OAuth 2.0 for Okta service apps using a private-key-JWT client-credentials grant with granular scopes (DPoP supported)
Change detection
Event Hooks send an HTTPS POST to a subscribed endpoint on events such as user.lifecycle.create and group.user_membership.add (after a one-time verification handshake); the System Log API (/api/v1/logs) is polled by the since parameter and the next Link header for a near-real-time change feed
Capabilities

Rate limits
Rate limits are enforced per org, per endpoint group, per minute and vary by Okta edition; responses carry X-Rate-Limit-Limit, X-Rate-Limit-Remaining, and X-Rate-Limit-Reset headers and exceeding one returns HTTP 429. The System Log is more tightly limited (about 120 requests/minute) and a separate concurrent-request cap (default 75 in-flight transactions) also applies.
