> Spark/Hive table support Boolean data type, the internal table also should
> support Boolean data type.
> Boolean data type Range: TRUE or FALSE. Do not use quotation marks around
> the TRUE and FALSE literal values. You can write the literal values in
> uppercase, lowercase, or mixed case. The values queried from a table are
> always returned in lowercase, true or false.
