@falizadeh - Thanks. Unfortunately, the current answer is that Great Expectations doesn’t have a native method to handle this internally unless the computing framework you’re working in can handle it. For example, this post talks about how to use Spark to load multiple files into one batch. Validate foreign keys / load multiple files to a single spark dataframe with batch generator
Spark supports specifying a path with multiple files and spark will read them into a data frame. So this works. Other frameworks may not support this. Great Expectations currently doesn’t handle that internally so you’d have to get all the files into a single file or dataframe before pointing Great Expectations to it.
