Important
We reserve the right to evolve this schema. Microsoft does not make any guarantees to maintain full backward compatibility with this published schema.
Follow these best practices:
No SELECT* // is supported because the column list can grow.
No user-generated schema modifications are supported.
No write operations are supported.
Test any queries that you build on representatively-sized databases to be sure that the queries can perform at a level to meet your needs.
