[英]Kafka Elasticsearch Connector Timestamps
I can see this has been discussed a few times here for instance but I think the solutions are out of date due to breaking changes in Elasticsearch.例如,我可以看到这里已经讨论过几次,但我认为由于 Elasticsearch 中的重大变化,这些解决方案已经过时。
I'm trying to convert a long/epoch field in my Json in my Kafka topic to an Elasticsearch date type which is pushed through the connector.我正在尝试将我的 Kafka 主题中的 Json 中的 long/epoch 字段转换为通过连接器推送的 Elasticsearch 日期类型。
When I try to add a dynamic mapping, my Kafka connect updates fail because Im trying to apply two mappings to a field, _doc and kafkaconnect.当我尝试添加动态映射时,我的 Kafka 连接更新失败,因为我尝试将两个映射应用于字段,_doc 和 kafkaconnect。 This was a breaking change around version 6 I believe where you can only have one mapping per index.
这是版本 6 的一项重大更改,我相信每个索引只能有一个映射。
{
"index_patterns": [ "depart_details" ],
"mappings": {
"dynamic_templates": [
{
"scheduled_to_date": {
"match": "scheduled",
"mapping": {
"type": "date"
}
}
}
]
}}
I've now focussed on trying to translate the message at source in the connector by changing the field to a timestamp, time or date.我现在专注于尝试通过将字段更改为时间戳、时间或日期来从连接器中的源翻译消息。
"transforms.TimestampConverter.type": "org.apache.kafka.connect.transforms.TimestampConverter$Value",
"transforms.TimestampConverter.field" : "scheduled",
"transforms.TimestampConverter.target.type": "Timestamp"
However, any messages I try to send through this transformer fail with但是,我尝试通过此转换器发送的任何消息都失败了
Caused by: org.apache.kafka.connect.errors.DataException: Java class class java.util.Date does not have corresponding schema type.

Seems like a really common thing to need to do, but I don't see how to get a date or time field into Elastic through this connector in version 7?似乎需要做一件很常见的事情,但我看不到如何通过版本 7 中的此连接器将日期或时间字段输入 Elastic?
The Confluent documentation states that the ES connector is currently not supported with ES 7. Confluent 文档指出,ES 7 当前不支持ES 连接器。
According to this issue , it might suffice to change type.name=kafkaconnect
to type.name=_doc
in your connector configuration.根据这个问题,在您的连接器配置
type.name=_doc
type.name=kafkaconnect
可能就足够了。
