Hi All,
We have a requirement to store nested json objects ( depth can be upto 5 levels) in elastic search. I have the current mapping
"dynamic_templates": [
{
"nested_feature": {
"match": "payload",
"mapping": {
"type": "object"
}
}
},
{
"nested_template": {
"path_match": "payload*.*", - match everything under payload
"match_mapping_type": "object", - if the dynamic mapping type is 'object' , make it 'nested'
"mapping": {
"type": "nested"
}
}
},
What I have in the dynamic templates will match ANY object and map it to a nested type. While it would preserve relationships of objects in arrays, it also means non-array objects will be treated the same as array objects and nested queries would be required for everything in the json object hierarchy.
Can anyone suggest a mapping to make non array objects as "Object" datatype and array objects as "Nested" datatype.
Note:All the fields inside json are dynamic.
Ex :json data
{
"ts": "2014-07-30T07:14:06.840",
"pid": 2104,
"tid": "1e88",
"sev": "info",
"req": "U9j9rgqgYVgAAA@kHr8AAAHs",
"sess": "B84F19DEC88D4362B9164D87A687CFBC-0:1",
"site": "Default",
"user": "nsawant",
"k": "begin-query",
"v": {
"protocol": "c4561a0",
"query": "(restrict (aggregate (select (project (table [Extract].[Extract]) (([yr:Date:ok] (year [Date])) ([none:Region:nk] [Region]) ([none:Country / Region:nk] [Country / Region]))) (= [none:Region:nk] \"Asia\")) (([none:Country / Region:nk] [none:Country / Region:nk])) (([avg:P: Population (count):ok] (average [P: Population (count)])))) ([none:Country / Region:nk] [avg:P: Population (count):ok]))"
}
}
Ex:json data
{
"data": [
