Why teams connect ClickHouse and Close
Sync Close 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. Users, Smart Views, Leads, Contacts from Close land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Close. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.
Common use cases
- Sync Close leads and opportunities into Postgres or a warehouse for pipeline reporting outside Close's built-in reports.
- Two-way sync between Close and a billing or ERP system so closed-won opportunities create customers and invoices automatically.
- Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
- Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
Scores and segments back on the record
Lead scores, churn risk, or usage segments computed in ClickHouse appear as fields in Close, where the people working accounts actually see them.
A single customer view
Join Close'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.
What you can sync between ClickHouse and Close
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 | Close objects | |
|---|---|---|
| Views Saved queries used as curated, read-only sync sources. | Users Sales reps referenced as owners on leads, opportunities, and activities. | |
| Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. | Smart Views Saved lead searches that can scope which records a segment-based sync pulls. | |
| Distributed tables Query-routing tables over cluster shards in self-managed deployments. | Leads The top-level record in Close; represents a company and holds its contacts, opportunities, and activity history. | |
| Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. | Contacts People nested under a lead, with emails and phone numbers used for outreach syncs. | |
| Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. | Opportunities Deal records with value, confidence, and status; commonly synced to reporting and billing systems. | |
| Databases Namespaces that group tables and scope permissions for sync users. | Activities Calls, emails, SMS, notes, and meetings logged against a lead; the source for engagement analytics. |
