trait Table extends AnyRef
An interface representing a logical structured data set of a data source. For example, the implementation can be a directory on the file system, a topic of Kafka, or a table in the catalog, etc.
This interface can mixin SupportsRead and SupportsWrite to provide data reading
and writing ability.
The default implementation of #partitioning() returns an empty array of partitions, and
the default implementation of #properties() returns an empty map. These should be
overridden by implementations that support partitioning and table properties.

Abstract Value Members
- abstract def capabilities(): Set[TableCapability]
Returns the set of capabilities for this table.
- abstract def name(): String
A name to identify this table.
A name to identify this table. Implementations should provide a meaningful name, like the database and table name from catalog, or the location of files for this table.

An ID of the table that can be used to reliably check if two table objects refer to the same metastore entity. If a table is dropped and recreated again with the same name, the new table ID must be different. This method must return null if connectors don't support the notion of table ID.

Returns the version of this table if versioning is supported, null otherwise.
This method must not trigger a refresh of the table metadata. It should return the version that corresponds to the current state of this table instance.
