HTAP Deployment - poor performance on the ColumnStore replication

Reported by customer

We configured HTAP using "Deploy an Enterprise HTAP Server with MariaDB Enterprise ColumnStore 1.5 and MariaDB Enterprise Server 10.5." documentation on URL

https://mariadb.com/docs/deploy/enterprise-htap/#deploy-target-enterprise-htap.

We have tested replication from innoDB to ColumnStore using this configuration and are experiencing poor performance on the ColumnStore replication. We are trying to insert 10,000 rows into the innoDB table and seeing very poor performance replicating to the ColumnStore table. Our main question is the utility cpimport being used in the replication process, and if not is there a way the replicate process can utilize cpimport to improve performance? Are we using the right deployment which would invoke cpimport in the replication process?
