How to use wildcard field in Aiven's ElasticSearch? - elasticsearch

Question

I wanted to test the new wildcard field type in my ElasticSearch instance (Aiven).
I've tried this:
PUT /wildcard_test
{
"mappings" : {
"properties" : {
"wildcard_field" : {
"type" : "wildcard"
}
}
}
}
And I'm getting this response:
{
"error" : {
"root_cause" : [
{
"type" : "mapper_parsing_exception",
"reason" : "No handler for type [wildcard] declared on field [wildcard_field]"
}
],
"type" : "mapper_parsing_exception",
"reason" : "Failed to parse mapping [_doc]: No handler for type [wildcard] declared on field [wildcard_field]",
"caused_by" : {
"type" : "mapper_parsing_exception",
"reason" : "No handler for type [wildcard] declared on field [wildcard_field]"
}
},
"status" : 400
}
Here are the info regarding the instance:
GET /
{
"name" : "...",
"cluster_name" : "...",
"cluster_uuid" : "...",
"version" : {
"number" : "7.9.3",
"build_flavor" : "unknown",
"build_type" : "unknown",
"build_hash" : "c4138e51121ef06a6404866cddc601906fe5c868",
"build_date" : "2020-10-16T10:36:16.141335Z",
"build_snapshot" : false,
"lucene_version" : "8.6.2",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
GET /_license
{
"error" : {
"root_cause" : [
{
"type" : "invalid_index_name_exception",
"reason" : "Invalid index name [_license], must not start with '_'.",
"index_uuid" : "_na_",
"index" : "_license"
}
],
"type" : "invalid_index_name_exception",
"reason" : "Invalid index name [_license], must not start with '_'.",
"index_uuid" : "_na_",
"index" : "_license"
},
"status" : 400
}
My understanding is that this feature is provided by X-Pack, which I don't whether or not is included in Aiven's service. Is there some way to make this work?

Answer 1

Although the wildcard field type was indeed added in v7.9, it's (unfortunately) only available as part of an X-Pack subscription and I presume the one running on Aiven is OSS which is missing this and other X-Pack features.
