[I] KafkaConnect Sink: Dynamic routing should respect iceberg.table.namespace [iceberg]
djakupovic opened a new issue, #14530:
URL: https://github.com/apache/iceberg/issues/14530
### Feature Request / Improvement
Hey,
my use case:
debezium cdc into kafka + iceberg kafka connect sink
iceberg kafka connect config:
topics.regex: '^dev\.(.*)' --> fetch every topic starting with dev so only one kafka iceberg sink connector which is great
idea:
sink into iceberg.table.namespace + topic name therefore $1 from the matcher of the regex. but currently that's not possible, this would be great if this could be handled.
improvement:
the dynamic feature is somehow great to sink data into the landing zone. However, if we use:
iceberg.tables.dynamic-enabled: "true"
iceberg.tables.route-field: "source_table" --> filed in the record called source_table
it does not respect the iceberg.table.namespace therefore not the schema e.g. "landing" and tries to write without any schema. So only the route-field as table name is being used instead namespace.route-field.
Therefore we need to create a field in the record with the schema in order to route but that's not a good idea to be honest. This feature should be somehow rewritten at least with iceberg.table.namespace being respected or even better with a regex pattern to fetch from the incoming topic name. the record itself should be independent from the target.
I do not see any possibility to do a 1:1 dynamic sink with the kafka connect iceberg sink at the current feature set.

I created a pull request for this. Would be great to have this feature in iceberg kafka connect so we can route dynamically with namespace awareness.
The pull request does not respect iceberg.table.namespace, instead a new field is being created called: "iceberg.tables.route-namespace"
