TableDdl

A descriptor of the specific SQL DDL statements required to manage a specific Comet table in a JDBC-accessible database engine

name: the name of the table as it is known on the database engine
createSql: the SQL Create Table statement with the database-specific type, constraints etc. tacked on.
pingSql: a cheap SQL query whose results are irrelevant but guaranteed to trigger an error in case the table is absent

Note: pingSql is optional, and will default to select * from $name where 1=0 as Spark SQL does
