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

Additionally, the following third-party migration tools are available:
