Method Detail

open

public void open()

Description copied from interface: ElasticsearchSinkFunction

Initialization method for the function. It is called once before the actual working process methods.

Specified by:

open in interface ElasticsearchSinkFunction<Tuple2<Boolean,Row>>

process

public void process(Tuple2<Boolean,Row> element,
                    RuntimeContext ctx,
                    RequestIndexer indexer)

Description copied from interface: ElasticsearchSinkFunction

Process the incoming element to produce multiple ActionsRequests. The produced requests should be added to the provided RequestIndexer.

Specified by:

process in interface ElasticsearchSinkFunction<Tuple2<Boolean,Row>>

Parameters:

element - incoming element to process

ctx - runtime context containing information about the sink instance

indexer - request indexer that ActionRequest should be added to
