When you run a mapping, in the native environment, to read a flat file that has unicode characters, a space, null values, single quotes, or a value that starts with a dollar sign, the Data Integration Service adds double quotes to the values when writing data to the target.

When you use the

Create Target

option to create a Microsoft Azure Blob Storage target and select Flat as the Resource Format, fields are not getting propagated to the target.

When you read data from or write data to Microsoft Azure Data Lake Store, the entire file gets downloaded in the staging directory even if you cancel the mapping.
