Logstash adding duplicate rows

Hello ,
We implemented a solution to push Microsoft SQL Data in form of simple rows from SQL Server to Logstash which will index the data to Elasticsearch. The data (SQL rows and columns) are getting successfully by using a simple jdbc plugin to logstash and logstash indexing the data to elasticsearch. But, everytime we try to pump the data (same data) what its doing is adding duplicate records with same data

input {
jdbc {
jdbc_driver_library => "/etc/logstash/sqljdbc42.jar"
jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
jdbc_connection_string => "jdbc:sqlserver://;user=sa;password=root;"
jdbc_user => "sa"
jdbc_password => "root"
statement => "SELECT * FROM hlidb.dbo.inf"
type => "pers"
jdbc {

    jdbc_connection_string => "jdbc:postgresql://"
    # The user we wish to execute our statement as
    jdbc_user => "postgres"
    jdbc_validate_connection => true
    jdbc_driver_library => "/etc/logstash/postgresql-42.0.0.jar"
    # The name of the driver class for Postgresql
    jdbc_driver_class => "org.postgresql.Driver"
    # our query
    statement => "SELECT * from contacts"
    type => "contact"

filter {
output {
elasticsearch {
hosts => ""

index => "sqltab"

document_type => "%{type}"
document_id => "%{uid}"

stdout { codec => rubydebug }


What's the origin of the uid field? Is it coming from the database table or is it something you're computing in a filter configuration that you didn't include in your post?
