Hello, I wrote a post on Friday (here) and since I didn't get a reply, I'll give it another go with a different question.
Just a quick summary (check my previous post for a more detailed explanation):
Currently on Elasticsearch 7.12.1, but I plan on upgrading to a newer version.
I have hierarchical types. Think object oriented design, inheritance of properties and all. I want to index that. I thought about indexing under separate indices in my previous post, but the first way I implemented it was with nested types.
So let's say that my structure of inheritance is as follows:
parent
child1
child3
child2
What I did was call PUT on /parent/mapping with body:
{
"properties": {
"parent.parent_property": {
"type": "text"
},
"parent.child1.child1_property": {
"type": "text"
},
"parent.child1.child3.child3_property": {
"type": "text"
},
"parent.child2.child2_property": {
"type": "text"
}
}
}
Calling GET on /parent/_mapping nets me the following result:
{
"parent": {
"mappings": {
"properties": {
"parent": {
"properties": {
"child1": {
"properties": {
"child1_property": {
"type": "text"
},
"child3": {
"properties": {
"child3_property": {
"type": "text"
}
}
}
}
},
"child2": {
"properties": {
"child2_property": {
"type": "text"
}
}
},
"parent_property": {
"type": "text"
}
}
}
}
}
}
}
My worry here is
a) whether this has anything to do with deprecated mapping types.
b) it will result in a single index. I assume it will take a performance hit
Can anyone give me any input at all?
