OceanBase OBLOADER & OBDUMPER consists of the import tool OBLOADER and the export tool OBDUMPER. OBLOADER provides very flexible command line options to import schema and data into OceanBase database in a variety of complex scenarios. OBLOADER is mainly used together with OBDUMPER. But in external business, OBLOADER also supports the import of files in CSV format which are exported by tools such as Navicat, Mydumper, and SQLDeveloper. OBLOADER makes full use of the features of the OceanBase distributed system, focusing on optimizing the performance of import. OBDUMPER can export the data in OceanBase to files in CSV format. At the same time, you can use this tool to export the objects defined in the database to a file.
