No, that is not possible. What is it you are looking to achieve? ---

I want fetch a message (and index value (primary\_key of a table )) from Kafka Queue and pass this jdbc input so that i can query it and send the data to Elasticsearch ---

How many records/documents would each query return? If you are simply looking up a value based on the key coming from Kafka, you may be able to use the [jdbc\_streaming](https://www.elastic.co/guide/en/logstash/current/plugins-filters-jdbc_streaming.html) plugin for this. ---

Only One key at a time, You mean I can use Kafka in the Input plugin and then use the Jdbc stream plugin to take input value from kafka and then run a query in the filter section and then in ouput section use elasticsearch right ? input{ kakfa {} } filter { jdbcstreaming } output { elasticsearch {} } Is this right ? Can you share example if you have any ? ---

Something like that. Do not have any example though. ---

But this is possible if implemented ? ---

@Christian_Dahlqvist, is it not possible to configure a TCP output for the first 'stage' and then a TCP input for the second 'stage'? ---

@patrick007 I think it should be possible, but I do not know anything about your data or queries. @wwalker I am not sure I understand what you are suggesting. Could you please add some more details on why TCP inputs would be useful here? ---
