Interface Table

public interface Table
Table provides different views (key-value vs record) and approaches (mapped-object vs binary) to access the data.

Binary table views might be useful in the various scenarios, including when the user key-value classes are not in classpath and/or when deserialization of the entire table record is undesirable for performance reasons.

Key-value views project table rows into key-value pairs, where all key columns are mapped to the key object, and the rest of the columns are mapped to the value object. Record and key-value views provide identical functionality, the projection is performed on the client side.
