Why teams connect Apache Cassandra and Smartsheet

Mirror Smartsheet's data into Apache Cassandra so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Smartsheet through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Apache Cassandra.

Stacksync mirrors Rows, Columns, Cells, Reports from Smartsheet into Collections, Counters, Keyspaces, Tables in Apache Cassandra and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Smartsheet, so the tool and the database never disagree.

Common use cases

  • 01 Two-way sync a project-tracker Sheet's Rows with a Postgres table so engineering works in SQL while project managers stay in Smartsheet.
  • 02 Write records from a CRM or ERP into Smartsheet Rows so ops teams manage intake and status in a grid, then push status Cells back to the source.
  • 03 Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.
  • 04 Sync customer profile data between Cassandra and a CRM so operational apps and sales tools agree.

Common sync patterns

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Smartsheet with a query

Records from Smartsheet are ordinary rows in Apache Cassandra; join them, index them, and use them in application logic without touching the vendor API.

Automate Smartsheet from your codebase

Write to the synced tables in Apache Cassandra and Stacksync propagates the change into Smartsheet, replacing custom integration code.

What you can sync between Apache Cassandra 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.

Apache Cassandra objects Smartsheet objects How this pairing syncs
Tables Wide-column tables addressed by partition key, the unit of row-level sync. 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. Tables is specific to Apache Cassandra and Sheets to Smartsheet — each maps to any object or custom field on the other side.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Rows Records inside a sheet, each with createdAt/modifiedAt and cells keyed by columnId; the primary unit synced to and from external tables. Partitions and Rows is specific to Apache Cassandra and Rows to Smartsheet — each maps to any object or custom field on the other side.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Columns Define sheet schema and cell type (TEXT_NUMBER, DATE, CONTACT_LIST, PICKLIST, CHECKBOX); read via the API so field mappings can be generated. Materialized Views is specific to Apache Cassandra and Columns to Smartsheet — each maps to any object or custom field on the other side.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Cells Row-by-column values; writes must match the column type and no single cell can exceed 4,000 characters. Secondary Indexes is specific to Apache Cassandra and Cells to Smartsheet — each maps to any object or custom field on the other side.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Reports Read-only roll-ups spanning multiple sheets; pulled into a warehouse for cross-sheet reporting, capped at 50,000 rows. User-Defined Types is specific to Apache Cassandra and Reports to Smartsheet — each maps to any object or custom field on the other side.
Collections List, set, and map columns handled with type-aware field mapping. Attachments Files linked to rows or sheets; posting one carries a 10x rate cost, so bulk file sync is throttled to 30 per minute. Collections is specific to Apache Cassandra and Attachments to Smartsheet — each maps to any object or custom field on the other side.

How changes propagate between Apache Cassandra 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.

Apache Cassandra Smartsheet Sub-second propagation

DetectionChanges in Apache Cassandra are captured at the source via change data capture — no polling loop against its API. Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns.

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

Smartsheet Apache Cassandra 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 written to Apache Cassandra through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apache Cassandra: No API quotas; throughput is governed by cluster capacity and consistency-level choices.
  • 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.
