Hi Fidea,
When specifying an ID, the IndexedRequest[1] can perform a complete overwrite.
If partial update is needed, the UpdateRequest[2] can be used.
@Override
public void process(
Tuple2<Integer, String> element, RuntimeContext ctx, RequestIndexer
indexer) {
UpdateRequest updateRequest = new UpdateRequest("index-name", "id-123");
Map<String, Object> jsonMap = new HashMap<>();
jsonMap.put("updated", new Date());
jsonMap.put("reason", "daily update");
updateRequest.doc(jsonMap);
indexer.add(updateRequest);
}
Best,
Jiabao
