回复： 每天0点数据写入Elasticsearch异常且kafka数据堆积
Mapping采用的template，格式如下：
"xxx-2020.04.23": {
"mappings": {
"doc": {
"dynamic_templates": [
{
"string_fields": {
"match": "*",
"match_mapping_type": "string",
"mapping": {
"type": "keyword"
}
}
}
],
"properties": {
"cost": {
"type": "long"
},
"result": {
"type": "keyword"
}
}
}
}
}
setting如下：
"xxx-2020.04.23": {
"settings": {
"index": {
"routing": {
"allocation": {
"total_shards_per_node": "1"
}
},
"refresh_interval": "10s",
"number_of_shards": "2",
"provided_name": "xxx-2020.04.23",
"creation_date": "1587509965602", -- 2020/4/22 6:59:25
"number_of_replicas": "0",
"uuid": "f9OqpCmJQnyqlqTeYpt1Sg",
"version": {
"created": "6020499"
}
}
}
}

主题: Re: 每天0点数据写入Elasticsearch异常且kafka数据堆积
hi,
es index 的 mapping 是否提前设置好了？
我看到异常 :
> failed to process cluster event (put-mapping) within 30s
像是自动建 mapping 超时了
