尝试使用 Kafka Connect 在 Elasticsearch 中索引 kafka 主题 [英] Trying to index kafka topic in Elasticsearch with Kafka Connect
问题描述
我想将一个主题从 avro 中的 kafka 索引到 elasticsearch 格式,但是我的时间戳字段有问题无法识别elasticsearch 作为日期格式字段.
I want to index a topic from kafka in avro to elasticsearch format but I have problems with my timestamp field to be recognized by elasticsearch as date format field.
我对连接器使用了以下配置.
I have used the following configuration for the connector.
{
"name": "es-sink-barchart-10",
"config": {
"connector.class": "io.confluent.connect.elasticsearch.ElasticsearchSinkConnector",
"value.converter": "io.confluent.connect.avro.AvroConverter",
"key.converter": "io.confluent.connect.avro.AvroConverter",
"key.converter.schema.registry.url": "http://localhost:8081",
"value.converter.schema.registry.url": "http://localhost:8081",
"connection.url": "http://localhost:9200",
"type.name":"type.name=kafka-connect",
"topics": "exchange_avro_01",
"topic.index.map": "exchange_avro_01:exchange_barchart",
"key.ignore": "true"
}
}
原始字段是 bigint 类型,我希望目标字段是具有任何有效格式的日期类型和 elasticsearch.我定义了一个动态模板,尝试通过以下方式解决:
The original field is bigint type and I want the target field to be date type with any valid format with elasticsearch. I have defined a dynamic template to try to solve it in the following way:
curl -XPUT "http://localhost:9200/_template/kafkaconnect/" -H 'Content-Type: application/json' -d'
{
"index_patterns": "exchange*",
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0
},
"mappings": {
"kafka-connect": {
"dynamic_templates": [
{
"dates": {
"match_mapping_type": "long",
"match": "TIME",
"mapping": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss"
}
}
}
]
,
"properties": {
"CLOSE": {
"type": "double"
},
.
.
.
}
}
}
}
}'
当我加载上述连接器时,没有任何内容被索引到 elasticsearch.
When I load the connector described above nothing is indexed to elasticsearch.
有什么帮助吗?
推荐答案
如果你的源代码是一个 bigint,那么它可能是一个 epoch.如果它是一个纪元,那么这将不起作用:
If your source is a bigint then presumably it's an epoch. If it's an epoch, then this won't work:
"mapping": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss"
}
因为你告诉 Elasticsearch 日期格式是 yyyy-MM-dd HH:mm:ss
(它不是).
because you're telling Elasticsearch that the date format is yyyy-MM-dd HH:mm:ss
(which it isn't).
因此,请尝试此操作(暂时省略您的自定义映射;先使其正常工作,然后再将其添加回来):
So instead, try this (omitting your custom mapping for the moment; get this working first and then add that back in):
{
"index_patterns": "exchange*",
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0
},
"mappings": {
"kafka-connect": {
"dynamic_templates": [
{
"dates": {
"match": "TIME",
"mapping": {
"type": "date"
} } } ] } } }
没有索引到elasticsearch.
nothing is indexed to elasticsearch.
检查 Kafka Connect 工作日志和 Elasticsearch 日志是否有任何错误.
Check the Kafka Connect worker log and the Elasticsearch log for any errors.
