I'm pretty new to logstash. I have an index called person in Kibana. The index includes firstname, lastname, email, address... Now I need to update person's address by using a table in database. My table only have emails and new addresses. I want to retrieve id in the elasticserach filter.  
Here's my config file:

input {  
jdbc{  
#jdbc library, connection string...  
}

```
statement => "select email, address from person_table"

```

}  
filter{  
elasticsearch {  
host =\>"myhost"  
index =\> "person"  
query =\> "email\_field:%{email}"  
fields =\> ["id"] # I want to retrieve id here and use it later, but couldn't make it work.  
}  
}

output{  
elasticsearch {  
host =\>"myhost"  
index =\> "person"  
action =\> "update"  
doc\_as\_upsert =\> "true"  
document\_id =\> "%{id}"  
}

docinfo is not availble in filter. How can I get the id?

Why not add a unique key to your database table that you can use as document id in Elasticsearch?

My table has an integer id. The document id in Elasticsearch for the index is a 33 character string. They are not equal. So I couldn't do document\_id =\>%{id} in output.

I would recommend reindexing the data with this id as document id as it will make updates much easier and more efficient.

If it's possible to retrieve document id and set it as parameter in filter and use it in output?
