Hi @javaht,
thank you for reporting it.
Currently, Spline agent doesn't support Doris format, but it should be possible to add a support for this by implementing a Spline agent plugin.
Could you possible try to do it and make a pull-request?

Here's a little bit of documentation about Spline agent plugins - https://github.com/AbsaOSS/spline-spark-agent#plugin-api
Example project for building Spline agent extensions (filters, dispatchers or plugins) - https://github.com/AbsaOSS/spline-getting-started/tree/main/spark-agent-extension-example

You can start with a simple solution by implementing the DataSourceFormatNameResolving trait (see AvroPlugin for example - https://github.com/AbsaOSS/spline-spark-agent/blob/develop/core/src/main/scala/za/co/absa/spline/harvester/plugin/embedded/AvroPlugin.scala)
If it's not enough then you might need to implement the RelationProviderProcessing trait (see KafkaPlugin, MongoPlugin, CassandraPlugin etc).

We would highly appreciate your contribution.
