Yes. Added the property to MockScanEntry. Need to add it to the
implementation as well, which is planned, but not yet complete.
> Allow "extended" mock tables access from SQL queries

> DRILL-5152 provided a simple way to generate sample data in SQL using a new,
> simplified version of the mock data generator. This approach is very
> convenient, but is inherently limited. For example, the limited syntax
> available in SQL does not encoding much information about columns such as
> repeat count, data generator or so on. The simple SQL approach does not allow
> generating multiple groups of data.
> However, all these features are present in the original mock data source via
> a special JSON configuration file. Previously, only physical plans could
> access that extended syntax.
> This ticket requests a SQL interface to the extended mock data source:
> {code}
> SELECT * FROM `mock`.`example/mock-options.json`
> {code}
> Mock data source options are always stored as a JSON file. Since the existing
> mock data generator for SQL never uses JSON files, a simple rule is that if
> the table name ends in ".json" then it is a specification, else the
> information is encoded in table and column names.
> The format of the data generation syntax is documented in the mock data
> source classes.
