我使用的kafkaconnect-mongosource配置如下:
curl -X PUT http://localhost:8083/connectors/mongo-source2/config -H "Content-Type: application/json" -d '{
"name":"mongo-source2",
"tasks.max":1,
"connector.class":"com.mongodb.kafka.connect.MongoSourceConnector",
"key.converter":"org.apache.kafka.connect.storage.StringConverter",
"value.converter":"org.apache.kafka.connect.storage.StringConverter",
"connection.uri":"mongodb://xxx:xxx@localhost:27017/mydb",
"database":"mydb",
"collection":"claimmappingrules.66667777-8888-9999-0000-666677770000",
"pipeline":"[{\"$addFields\": {\"something\":\"xxxx\"} }]",
"transforms":"dropTopicPrefix",
"transforms.dropTopicPrefix.type":"org.apache.kafka.connect.transforms.RegexRouter",
"transforms.dropTopicPrefix.regex":".*",
"transforms.dropTopicPrefix.replacement":"my-topic"
}'
出于某种原因,当我使用消息时,我会得到一个奇怪的密钥:
"_id": {
"_data": "825DFD2A53000000012B022C0100296E5A1004060C0FB7484A4990A7363EF5F662CF8D465A5F6964005A1003F9974744D06AFB498EF8D78370B0CD440004"
}
我不知道它是从哪里来的,我的mongo文档的id是uuid,当我消费消息时,我希望在我的消费者密钥处看到documentkey字段。
以下是连接器发布到Kafka的消息示例:
{
"_id": {
"_data": "825DFD2A53000000012B022C0100296E5A1004060C0FB7484A4990A7363EF5F662CF8D465A5F6964005A1003F9974744D06AFB498EF8D78370B0CD440004"
},
"operationType": "replace",
"clusterTime": {
"$timestamp": {
"t": 1576872531,
"i": 1
}
},
"fullDocument": {
"_id": {
"$binary": "+ZdHRNBq+0mO+NeDcLDNRA==",
"$type": "03"
},
...
},
"ns": {
"db": "security",
"coll": "users"
},
"documentKey": {
"_id": {
"$binary": "+ZdHRNBq+0mO+NeDcLDNRA==",
"$type": "03"
}
}
}
