limit of 400 concurrent Copy Data activities
Hi, I’m experiencing a concurrency issue when running my orchestrator in Fabric. I’m using the Trial version with an F64 SKU. The error is as follows:
There are substantial concurrent copy activity executions which is causing failures due to throttling under subscription XXXXX-XXXXXX-XXXXX, region ne and limitation 400. Please reduce the concurrent executions.
ErrorCode: UserErrorWithLargeConcurrentRuns.
If I increase the capacity, should this issue be resolved? In other words, is capacity related to the concurrency level?
Thanks.
Based on the documentation,

that seems to be an issue at fabric level

- Hello AgustinPlain
Adding few other details in additiin to NandanHegde - Fabric allocates computing resources through CU providing a different amount of capacity
- One Capacity Unit = two Apache Spark VCores for compute-intensive operations
Capacity defines the ability of resources to perform activities or produce output, but does not directly control concurrency limits
The 400-activity concurrent execution limit exists independently of your purchased capacity SKU
Increasing your capacity from F64 to a higher SKU will provide more computational power but will not increase the 400 concurrent Copy activity limit
Potential solutiom would be :
Implement staggered pipeline scheduling to ensure that not all Copy activities attempt to run simultaneously
