In This Chapter

This chapter describes how Extended Parallel Server performs high-performance loading with external tables. An external table is a data file that you use to load and unload data. The data file is not managed by an Informix database server. The definition of the external table includes data-formatting type, external data description fields, and global parameters.

This chapter describes the following tasks:

• Getting an overview of high-performance loading
• Starting to load and unload data
• Loading, unloading, and reorganizing data
• Loading simple large objects
• Monitoring the load or unload operations
• Recovering after errors
