Ma configuration dans kafka-connect-JDBC est:.

name=task-view-list-stage 
connector.class=io.confluent.connect.jdbc.JdbcSourceConnector 
tasks.max=10 
connection.url=jdbc:postgresql://localhost:5432/postgres?user=postgres&password=test 
table.types=TABLE 
query=select * from employee_master 
mode=timestamp+incrementing 
incrementing.column.name=employee_master_id 
timestamp.column.name=modified_date 
validate.non.null=false 
topic.prefix=my-id-app

Et mon kafka-connect configuration ElasticSearch est:

name=es-id-view 
connector.class=io.confluent.connect.elasticsearch.ElasticsearchSinkConnector 
tasks.max=1 
topics=my-id-app 
topics.key.ignore=false 
transforms=InsertKey 
transforms.InsertKey.type=org.apache.kafka.connect.transforms.ValueToKey 
transforms.InsertKey.fields=employee_master_id 
connection.url=http://localhost:9200 
type.name=type_id

Ma structure de table est:

employee_master_id | emp_name | modified_date 
----------------------------------------------------------- 
1     | Bala | "2017-05-18 11:51:46.721182+05:30" 
------------------------------------------------------------------- 
2     | murugan | "2017-05-21 15:59:11.443901+05:30" 
-------------------------------------------------------------------

Pour d'autres qui traversent ce sujet, voir discussion liés: https://groups.google.com/d/topic/confluent-platform/2jaRg-oT -p4/discussion –

En plus comme ValueToKey vous avez besoin de ExtractField pour convertir la clé d'un objet à un champ simple:

transforms=InsertKey,ExtractId 
transforms.InsertKey.type=org.apache.kafka.connect.transforms.ValueToKey 
transforms.InsertKey.fields=employee_master_id  
transforms.ExtractId.type=org.apache.kafka.connect.transforms.ExtractField$Key 
transforms.ExtractId.field=employee_master_id
