Create Mappings for DB output columns in Logstash configurations file

Hello everyone,
I'm new to logstash and elastic search.Please help me out on the below
We are working on loading data from SQL Server database onto elasticsearch.(Version 6.2.4)

The below is the simple configuration

input {
jdbc {
jdbc_driver_library => "sqljdbc4-2.0.jar"
jdbc_connection_string => "jdbc:sqlserver://localhost:1433;databaseName=sampleDB;MultiSubnetFailover=True;"
jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
jdbc_user => ""
jdbc_password => "
****"
statement => "SELECT name , salary from Test"
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index => "es_mappings"
document_type => "DOCUMENT_TYPE"
document_id => "es_configurations"
}
stdout { codec => rubydebug }
}

The above works as expected.

When we try to add mappings to it like below configuration :slight_smile:

input {
jdbc {
jdbc_driver_library => "sqljdbc4-2.0.jar"
jdbc_connection_string => "jdbc:sqlserver://localhost:1433;databaseName=sampleDB;MultiSubnetFailover=True;"
jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
jdbc_user => ""
jdbc_password => "
****"
statement => "SELECT name , salary from Test"
}
}
mappings : {
"properties": {
"name": {
"type": "string",
"index": "not_analyzed",
"include_in_all": false
}
}

		}

output {
elasticsearch {
hosts => ["localhost:9200"]
index => "es_%{slice}_mappings"
document_type => "DOCUMENT_TYPE"
document_id => "es_configurations"
}
stdout { codec => rubydebug }
}

It throws an error.

Can someone please specify how we need to map a DB column output in elastic search for the below properties
"type": "string",
"index": "not_analyzed",
"include_in_all": false

The below is the error log:

Mappings can't be stored in the Logstash configuration file. Read about index templates in the ES documentation and check out the template-related configuration options of the elasticsearch output.
