Limits and restrictions

This section outlines the default data modeling limits for a CDF project and the values that are reserved for internal Cognite use.

注意

If you need to increase limits for a CDF project, contact Cognite support.

Limits

Name	Maximum value
Spaces	100
Containers	1,000
Container properties	100
Views	10,0001
View versions	100
View properties	100
Levels of nested views ("implements")	10
Data models	100
Data model versions	100
Data model views	100
Total properties	25,000
Enum values in an enum property	32
Live instances	5,000,000
Soft deleted instances	10,000,000
Concurrent instance apply operations	4
Concurrent instance delete operations	2
Concurrent instance query operations	8
Max size - text	128000 bytes (UTF-8)
Max size - json	40960 bytes (UTF-8)
Max items - arrays	1000 items
Max items - arrays (direct relations)	100 items

¹ The limit includes the number of versions per model. If you have 100 views, each with 100 versions, you have consumed 10,000 views.

Concurrency limits

Concurrency limits are project-wide. By default, you can have up to 4 concurrent apply operations, 2 concurrent delete operations, and 8 concurrent query operations in total at any given time.

Transformations can use a maximum of 75% of the budget while the remaining 25% is reserved for other clients.

If a request exceeds any of the concurrency limits, it will be throttled with a 429 Too Many Requests response.

Reserved values

We've reserved some property values for Cognite internal use and to prevent GraphQL issues. You can't use the reserved values in your data models.

Views and containers

For views and containers, we reserve these values:

• For externalId:

  Boolean, Date, Float32, Float64, Float, Int32, Int64, Int, JSONObject, Mutation, Numeric, PageInfo, Query, String, Subscription, TimeSeries, File, Sequence, and Timestamp.

• For properties:

  createdTime, deletedTime, edge_id, extensions, externalId, lastUpdatedTime, node_id, project_id, property_group, seq, space, version, tg_table_name, startNode, and endNode.

Spaces

For spaces, we reserve these values:

• For space:

  cdf, dms, edge, node, pg3, shared, space, mapping, system, constraint, edge_source, history, identifier_by_space, index, node_source, project, property_group_constraint, property_group_index, property_group, property_group, property, and version_info.
