When performing bulk inserts in Azure Cosmos DB, there are certain limitations and considerations to keep in mind. One potential error message you might encounter related to bulk insert speed limits is:
"Request rate is large. More Request Units may be needed, so no further request is being sent. Please retry after some time, or adjust the RUs per second on your collection or database to allow for higher request rates."
This error message indicates that the request rate for your bulk inserts is exceeding the provisioned Request Units (RUs) per second for your Cosmos DB collection or database. Azure Cosmos DB uses Request Units as a measure of throughput, representing the cost of a request in terms of CPU, memory, and I/O resources.
1. Increase the provisioned RUs per second for your collection or database: By scaling up the RUs, you allocate more throughput capacity to handle higher request rates. You can adjust the RUs through the Azure portal, Azure CLI, or Azure PowerShell.
2. Split the bulk insert operation into multiple smaller batches: Instead of inserting all the data in a single bulk operation, divide it into smaller batches and perform the inserts over time. This approach helps distribute the request rate more evenly, preventing the error.
3. Implement client-side throttling: If you are using a custom application to perform the bulk inserts, you can introduce client-side throttling logic to control the request rate and avoid exceeding the provisioned RUs.
By following these steps, you should be able to mitigate the error related to bulk insert speed limits in Azure Cosmos DB.
