Interface ExternalTable

All Superinterfaces:

RowSource, Table

All Known Implementing Classes:

BaseFlatfileTable, DelimitedFlatfileTable, ExternalDatabaseTable

public interface ExternalTable

extends Table

Extends Table interface to accept configuration parameters associated with connecting a table to an external resource, such as a flatfile or external JDBC-compatible database.

Typically the external tables or data file are pre-existing so, we need to get more meta information about the data organization so that it can load those existing data file as Axion table.
