CDF Data Modeling: Limits, Concurrency & Best Practices

This is a reference skill. When writing or reviewing code that calls CDF Data Modeling APIs, apply the patterns below.

DMS Limits Reference

For the latest concurrency limits, resource limits, and property value limits, see the official documentation: https://docs.cognite.com/cdf/dm/dm_reference/dm_limits_and_restrictions

Key things to be aware of:

• Instance apply, delete, and query operations each have their own concurrent request limits
• Exceeding these limits returns 429 Too Many Requests
• Transformations consume a large portion of the concurrency budget, leaving less for other clients
• instances.list has a max page size (use pagination for complete results)
• instances.query table expressions each have their own item limit
• instances.upsert accepts up to 1000 items per call
• in filters accept at most 1000 values per expression; larger sets must be split into batches
