Why teams connect ClickHouse and Smartsheet

Get the data locked inside Smartsheet into ClickHouse as live tables, and send results back where Smartsheet can use them, without writing a pipeline.

Whatever Smartsheet is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Reports, Attachments, Discussions and Comments, Users and Groups from Smartsheet into tables in ClickHouse continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in ClickHouse can also be written back into fields in Smartsheet where the tool can use them.

Common use cases

  • 01 Pull Reports and Sheets into a warehouse for cross-project reporting and dashboards without manual CSV exports.
  • 02 Mirror Users and Groups from an HR system or directory so sheet sharing and workspace access stay aligned with headcount changes.
  • 03 Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • 04 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.

Common sync patterns

History that outlives the tool

A continuously synced copy in ClickHouse preserves a queryable record even as data ages out of Smartsheet or gets changed inside it.

Analytics on Smartsheet's data

Records and events from Smartsheet land in ClickHouse as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine Smartsheet's data with data from every other synced system to answer questions no single tool can.

What you can sync between ClickHouse and Smartsheet

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 Smartsheet objects How this pairing syncs
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Discussions and Comments Threaded comments on rows and sheets; read out to sync collaboration history or activity into another system. Materialized views is specific to ClickHouse and Discussions and Comments to Smartsheet — each maps to any object or custom field on the other side.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Users and Groups Account membership and sharing; synced to keep an HR or identity source aligned with sheet and workspace access. Distributed tables is specific to ClickHouse and Users and Groups to Smartsheet — 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. Sheets The core container; each sheet has typed columns, rows, and a modifiedAt stamp. Stacksync treats a sheet as a table and syncs its rows two-way. Dictionaries is specific to ClickHouse and Sheets to Smartsheet — 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. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Tables (MergeTree family) is specific to ClickHouse and Rows to Smartsheet — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Databases is specific to ClickHouse and Columns to Smartsheet — each maps to any object or custom field on the other side.
Views Saved queries used as curated, read-only sync sources. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. Views is specific to ClickHouse and Cells to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse and Smartsheet

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

Smartsheet ClickHouse Sub-second propagation

DetectionSmartsheet notifies Stacksync of record changes through webhook events. Sheet-scoped webhooks subscribed to *.* events notify on row and cell changes.

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

Rate-limit considerations

  • Smartsheet: 300 requests per minute per access token; heavy calls like posting attachments cost 10x (30/min). A 429 returns errorCode 4003, back off ~60s.
