The shredding procedure processes in a streaming fashion (the whole document is not loaded into memory all at once) each of the documents returned by evaluating the SQL query specified by queryString. The annotated schema is used to extract the values of interest from each of the documents and the target tables are updated using these values. During this process, if an externalContext is specified, any configuration values specified are used to override equivalent parameters in the annotated schema mapping.
