title: Increase parallel copy in Azure Data Factory
body: <p>I'm trying to perform ADF copy activity from CosmosDB to Azure Blob Container. The degree of copy parallelism is always 1, even if I specify a greater value. what determines the parallelism value and how do I increase it ? . If the copy is from CosmosDB to another CosmosDB , I could achieve more than 1 parallel copies. But when the sink is blob container, I'm facing the issue.</p>
  <p>Currently, the pipeline is writing into single file in Azure Blob Container. But I don't see an option to write multiple output files , incase if that helps to increase parallel copy.</p>
