Hi, all,
I use Elastic Search to store some JSON data like the following:
{
"_index" : "normalized",
"_type" : "90A2DAFB0621",
"_id" : "Fri Sep 12 16:59:50 UTC 2014",
"_score" : 1.0,
"_source":{"id":"2014-09-12T16:59:50.000Z","r":72.16,"o":74.3,"m":78.01,"s":66.99,"c":0.03,"p":2.77,"e":7.694444444444444E-6,"ec":1.8466666666666666E-6,"mo":0,"ot":64.31,"ecop":91}
}
I changed how "_id" is calculated in my program later on. Then, in the old data
sets, there are two duplicated items for older data. I was able to find the
duplicated items using the aggregation API:
{
"aggs": {
"types": {
"terms": {
"field": "_type"
},
"aggs": {
"dups": {
"histogram": {
"field": "id",
"interval": 1,
"min_doc_count": 2
}
}
}
}
}
}
I can remove the old data one by one using the delete API. But I wonder if
there are any better solutions.
Thanks a lot for your help!
Jingzhao
