You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: _sapo_data_parallelism_config.rs
    path of file: ./repos/aws-sdk-rust/sdk/appflow/src/types
    
    the code of the file until where you have to start completion: // Code generated by software.amazon.smithy.rust.codegen.smithy-rs. DO NOT EDIT.

/// <p>Sets the number of <i>concurrent processes</i> that transfer OData records from your SAP instance. A concurrent process is query that retrieves a batch of records as part of a flow run. Amazon AppFlow can run multiple concurrent processes in parallel to transfer data faster.</p>
