THE REALITY

ClickHouse is brilliant at what it does. Useless at everything else your data needs to touch.

ClickHouse is the fastest open-source OLAP engine you can run, so teams point everything at it - and then the integration story breaks. Custom apps proxy queries through bespoke layers. Per-tenant row policies live in app code. AI agents query without lineage. Sharded clusters need orchestration ClickHouse-keeper alone wasn't designed to expose to ops systems.

The integration tool you've already tried probably can't fix it.

What Zapier + iPaaS reach

SaaS-to-SaaS. Useful, until it isn't.

Connectors for ClickHouse, Slack + a thousand other SaaS apps. Cheap + fast for the easy half of integration. Where they hit a wall:

CRM, ERP + customer-facing apps reading ClickHouse through brittle proxy layers rather than governed integrations
Real-time CDC from operational OLTP into ClickHouse via Kafka table engines + Materialized Views
AI agents querying ClickHouse live through MCP rather than batched analytical jobs
Customer-facing apps backed by ClickHouse with MergeTree-aware caching + per-tenant row policies
Multi-shard + replica routing across ClickHouse Cloud + self-hosted clusters

What Rayven reaches

Ops, apps, agents, BI + AI. One platform.

The integration platform built for what other tools can't (or won't) reach - plus an AI data fabric, MCP server + app builder layered on top. Australian-priced.

ClickHouse + every CRM, ERP + operational system
Streaming, CDC, files, APIs + custom-built connectors.
Files, legacy SQL, FTP + custom-built connectors
Real-time bidirectional sync, tier-aware + rate-limit-safe
AI Data Fabric, MCP, automation + custom apps included

WHAT YOU CAN BUILD

ClickHouse + Rayven: AI, automation + tools that reach every system you run.

What is ClickHouse integration?

ClickHouse integration is the practice of connecting ClickHouse to the rest of your business stack - CRM, ERP, customer-facing apps + AI agents - so OLAP data is usable everywhere it matters. Rayven delivers ClickHouse integration as part of an AI data fabric, not a bespoke proxy layer.

How does Rayven connect ClickHouse to other systems?

Rayven uses ClickHouse's HTTP interface, Native protocol, JDBC/ODBC, Kafka table engines + Materialized Views for real-time bidirectional sync. Basic, LDAP + SSL authentication + ClickHouse Cloud OAuth handled per environment. See the Rayven Platform for the integration + data layers.

What systems can Rayven connect ClickHouse to?

Rayven connects ClickHouse to 600+ systems including Salesforce, HubSpot CRM, NetSuite ERP, Xero, Kafka, Kinesis, S3, GCS + custom OLTP databases - plus AI agents via Rayven MCP.

How does Rayven handle ClickHouse sharding + replication?

Rayven's routing layer is shard + replica-aware. Operational reads route to the closest replica; analytical workloads scatter-gather across shards. ClickHouse Keeper coordination respected end-to-end. See the data layer for the model.

Does ClickHouse have a native API? Why does Rayven add value on top?

Yes - ClickHouse ships HTTP interface, Native protocol, JDBC/ODBC, Kafka + Kinesis table engines + Materialized Views. Rayven adds value because production sync needs more than a connector: MergeTree-aware routing, sharded cluster orchestration, MCP-grade AI access + the apps + portal layers on top. Read more in how Rayven works.

What are the most common ClickHouse integration use cases?

Top use cases are Kafka-engine CDC, reverse ETL to CRM + ERP, Claude querying ClickHouse via MCP, sharded cluster federation + customer-facing apps backed by real-time OLAP. See the automations above for specifics.

What are the technical specifics of ClickHouse integration with Rayven?

Rayven uses ClickHouse's HTTP interface, Native protocol, JDBC/ODBC drivers + Kafka table engines for real-time bidirectional sync, authenticated via Basic, LDAP, SSL + ClickHouse Cloud OAuth with per-cluster credential rotation. Kafka + Kinesis table engines drive sub-millisecond CDC into MergeTree tables; Materialized Views fire on insert so downstream aggregations stay live without polling. Shard + replica-aware query routing means operational reads route to the closest replica while analytical workloads scatter-gather across all shards. MergeTree engine family choice (ReplacingMergeTree, AggregatingMergeTree, SummingMergeTree) preserved across every flow into CRM, ERP, AI agents + custom apps. Row-level access + role-based access policies travel through the connection. Sharded clusters across self-hosted + ClickHouse Cloud reconcile via Rayven's customer-master layer with per-shard query routing. Claude + your AI agents query ClickHouse through Rayven MCP. Validated against self-hosted + ClickHouse Cloud deployments + the Rayven Platform.
