h2. What is the captured database version and mode of deployment?

postgres 18, k8s cloudnativepg operator
h2. What behavior do you expect?

composite config is being used correctly, maybe also bug in openlineage itself

debezium does not send its configuration into kafka
h2. What behavior do you see?

composite problem:

does not work. needs to be set by env variables in order to work like:
env:
        - name: OPENLINEAGE__TRANSPORT__TYPE
          value: "composite"
        - name: OPENLINEAGE__TRANSPORT__CONTINUE_ON_FAILURE
          value: "true"
        - name: OPENLINEAGE__TRANSPORT__TRANSPORTS__MARQUEZ__TYPE
          value: "http"
        - name: OPENLINEAGE__TRANSPORT__TRANSPORTS__MARQUEZ__URL
          value: "http://marquez:5000"
        - name: OPENLINEAGE__TRANSPORT__TRANSPORTS__MARQUEZ__ENDPOINT
          value: "api/v1/lineage"
        - name: OPENLINEAGE__TRANSPORT__TRANSPORTS__MARQUEZ__COMPRESSION
          value: "gzip"
        - name: OPENLINEAGE__TRANSPORT__TRANSPORTS__KAFKA__TYPE
          value: "kafka"
        - name: OPENLINEAGE__TRANSPORT__TRANSPORTS__KAFKA__TOPIC_NAME
          value: "dev.openlineage.postgres.debezium"
        - name: OPENLINEAGE__TRANSPORT__TRANSPORTS__KAFKA__PROPERTIES
          value: "mykafka:9090"
h2. Do you see the same behaviour using the latest released Debezium version?

yes 3.3.0 final
h2. Do you have the connector logs, ideally from start till finish?

Yes but logs are all fine
h2. How to reproduce the issue using our [tutorial|https://github.com/debezium/debezium-examples/tree/main/tutorial] deployment?

look at the created kafka messages from debezium from openlineage. they send the whole debezium config with it, so with db credentials etc.
h1. Feature request or enhancement

do not send config of debezium into openlineage kafka topci
h2. Which use case/requirement will be addressed by the proposed feature?

security
h2. Implementation ideas (optional)

openlineage configuration
