我正在使用 druid 快速入门附带的 wikiticker-index.json 文件在 druid 中进行批量摄取。
以下是我在 wikiticker-index.json 文件中的数据架构。
{
type:"index_hadoop",
spec:{
ioConfig:{
type:"hadoop",
inputSpec:{
type:"static",
paths:"quickstart/wikiticker-2015-09-12-sampled.json"
}
},
dataSchema:{
dataSource:"wikiticker",
granularitySpec:{
type:"uniform",
segmentGranularity:"day",
queryGranularity:"none",
intervals:[
"2015-09-12/2015-09-13"
]
},
parser:{
type:"hadoopyString",
parseSpec:{
format:"json",
dimensionsSpec:{
dimensions:[
"channel",
"cityName",
"comment",
"countryIsoCode",
"countryName",
"isAnonymous",
"isMinor",
"isNew",
"isRobot",
"isUnpatrolled",
"metroCode",
"namespace",
"page",
"regionIsoCode",
"regionName",
"user"
]
},
timestampSpec:{
format:"auto",
column:"time"
}
}
},
metricsSpec:[
{
name:"count",
type:"count"
},
{
name:"added",
type:"longSum",
fieldName:"added"
},
{
name:"deleted",
type:"longSum",
fieldName:"deleted"
},
{
name:"delta",
type:"longSum",
fieldName:"delta"
},
{
name:"user_unique",
type:"hyperUnique",
fieldName:"user"
}
]
},
tuningConfig:{
type:"hadoop",
partitionsSpec:{
type:"hashed",
targetPartitionSize:5000000
},
jobProperties:{
}
}
}
}
摄取样本 json后。仅显示以下指标。
我找不到 longSum metrics.ie 添加、删除和增量。有什么特别的原因吗？
有人知道吗？
提前致谢。
