Why teams connect ClickHouse and Seismic

Sync Seismic into ClickHouse continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Content Versions, Users, User Groups, Teamsites from Seismic land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Seismic. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • 01 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
  • 02 Extract content-interaction and LiveSend engagement from the Reporting API v2 into a warehouse to tie asset views to CRM Opportunities.
  • 03 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • 04 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.

Common sync patterns

A single customer view

Join Seismic's relationship data with billing, product, and support data in ClickHouse to build the customer picture the CRM alone cannot hold.

Cleanup that sticks

Deduplication and normalization done in ClickHouse can be written back, so warehouse-side cleanup actually fixes the CRM.

CRM analytics on live data

Accounts, contacts, and activity from Seismic are queryable in ClickHouse moments after they change, so dashboards stop lagging the reality they describe.

What you can sync between ClickHouse and Seismic

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 Seismic objects How this pairing syncs
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Digital Sales Rooms Buyer-facing microsites (DSRs); lifecycle and content-change events surface via webhooks, currently marked Early Access. Materialized views is specific to ClickHouse and Digital Sales Rooms to Seismic — each maps to any object or custom field on the other side.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. Distributed tables is specific to ClickHouse and Reporting Activities to Seismic — each maps to any object or custom field on the other side.
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. Dictionaries is specific to ClickHouse and Library Content to Seismic — 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. Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. Tables (MergeTree family) is specific to ClickHouse and Content Versions to Seismic — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Databases is specific to ClickHouse and Users to Seismic — each maps to any object or custom field on the other side.
Views Saved queries used as curated, read-only sync sources. User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. Views is specific to ClickHouse and User Groups to Seismic — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse and Seismic

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 Seismic 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 Seismic through its API, with automatic retries and rate-limit backoff.

Seismic ClickHouse Sub-second propagation

DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.

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

Rate-limit considerations

  • Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.
