Migrating Data from Other OLAP

To migrate data from other OLAP systems to Doris, you have several options:

• For systems like Hive/Iceberg/Hudi, you can use Multi-Catalog to map them as external tables and then use "Insert Into" to load the data

• You can export data from the OLAP system into formats like CSV, and then load these data files into Doris

• You can use systems like Spark/Flink, utilizing the OLAP system's Connector to read data, and then call the Doris Connector to write into Doris

NOTE

If you know of other migration tools that could be added to this list, please contact dev@doris.apache.org
