Elastic Dynamic field mapping - elasticsearch

Question

ES version 6.8.12
I want to map all types to a given field in an index, it should store all types of data , instead of bound to specific type.
im facing issue when the string is stored in Long type field.
[WARN ] 2020-09-14 06:34:36.470 [[main]>worker0] elasticsearch - Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>"5f4632bab98bdd75a267546b", :_index=>"cdrindex", :_type=>"doc", :routing=>nil}, #<LogStash::Event:0x38a5506>], :response=>{"index"=>{"_index"=>"cdrindex", "_type"=>"doc", "_id"=>"5f4632bab98bdd75a267546b", "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse field [caller_id_number] of type [long] in document with id '5f4632bab98bdd75a267546b'", "caused_by"=>{"type"=>"illegal_argument_exception", "reason"=>"For input string: \"Anonymous\""}}}}}

Answer 1

Then you need to pick the text or keyword data type.
In your mapping, you need to set the caller_id_number data type explicitly to one of the above instead of letting Elasticsearch decide for you.
For instance:
PUT your-index
{
"mappings": {
"properties": {
"caller_id_number": {
"type": "text"
},
...
}
}
}
Note that you can leverage dynamic mappings if you want to automatically set the mapping for some fields:
PUT your-index
{
"mappings": {
"dynamic_templates": [
{
"sources": {
"match": "caller_*",
"mapping": {
"type": "text"
}
}
}
],
"properties": {
"specific_field": {
"type": "long"
}
}
}
}
With the dynamic mapping above, all fields starting with caller_ would get automatically mapped as text while specific_field would be mapped as long...
