org.apache.tika.pipes.pipesiterator.jdbc.JDBCPipesIterator

All Implemented Interfaces:

Iterable<FetchEmitTuple>, Callable<Integer>, Initializable

public class JDBCPipesIterator
extends PipesIterator
implements Initializable

Iterates through a the results from a sql call via jdbc. This adds all columns (except for the 'fetchKeyColumn' and 'emitKeyColumn', if specified) to the metadata object.

• If a 'fetchKeyColumn' is specified, this will use that column's value as the fetchKey.
• If no 'fetchKeyColumn' is specified, this will send the metadata from the other columns.
• The 'fetchKeyColumn' value is not added to the metadata.

• An 'emitKeyColumn' must be specified
• The 'emitKeyColumn' value is not added to the metadata.
