Answer 1

Hi @Deepak Patil , welcome to Microsoft Q&A forum.

We need to use below properties to get/set the concurrency in java sdk for Azure Cosmos DB:

getMaxDegreeOfParallelism

setMaxDegreeOfParallelism

This is available for all the sdk versions and we can use it with CosmosQueryRequestOptions class.

CosmosQueryRequestOptions options = new CosmosQueryRequestOptions();  
  
        // 0 maximum parallel tasks, effectively serial execution  
        options.setMaxDegreeOfParallelism(0);  

Please refer to below code snippet for more details:
