I am having a hard time in figuring the dynamic template which can define the parent-child relationship for ES 6.x . Any examples are welcome ...

Basically, I have a root and child documents (parent-child). Currently, I do the following explicit mapping:

PUT index-2018.06.05  
{  
"mappings": {  
"\_doc": {  
"properties": {  
"join\_field": {  
"type": "join",  
"relations": {  
"root": "child"  
}  
}  
}  
}  
}  
}

Is it possible for me to define the same as part of a dynamic template?

I managed to the same with two templates with different ordering numbers. Hope it helps someone.  
{  
"index\_patterns": [  
"discovery-\*"  
],  
"order": 0,  
"mappings": {  
"\_doc": {  
"properties": {  
"join\_field": {  
"type": "join",  
"relations": {  
"topo": "document"  
}  
}  
}  
}  
}  
}

PUT \_template/discovery-events  
{  
"order": 1,  
"index\_patterns": [  
"discovery-_"  
],  
"settings": {  
"index": {  
"number\_of\_shards": "1",  
"number\_of\_replicas": "1"  
}  
},  
"mappings": {  
"\_doc": {  
"dynamic\_templates": [  
{  
"timestamp": {  
"mapping": {  
"format": "strict\_date\_optional\_time||epoch\_millis",  
"type": "date"  
},  
"match\_mapping\_type": "long",  
"path\_match": "timestamp"  
}  
},  
{  
"name": {  
"mapping": {  
"type": "keyword"  
},  
"match\_mapping\_type": "string"  
}  
},  
{  
"namespace": {  
"mapping": {  
"type": "keyword"  
},  
"match\_mapping\_type": "string"  
}  
},  
{  
"doctype": {  
"mapping": {  
"type": "keyword"  
},  
"match\_mapping\_type": "string"  
}  
},  
{  
"dimensions": {  
"mapping": {  
"type": "nested",  
"eager\_global\_ordinals": true  
},  
"match": "_",  
"match\_mapping\_type": "object"  
}  
},  
{  
"values": {  
"mapping": {  
"type": "nested",  
"eager\_global\_ordinals": true  
},  
"match": "\*",  
"match\_mapping\_type": "object"  
}  
}  
]  
}
