To speed up the loading of data, many DBAs prefer to use the load tool for data migration and loading, but the load utility brings us some problems as well, and today focuses on the solution when we encounter problems when we use the Load tool again.As we all know, the load process is divided into 4 stages: Load/build/delete/index copy. The load phase is a format that parser the source files into the physical data store, directly into the page, not through the
