Text Load Set Table Descriptors
Oracle LSH can read the data structure from a metadata (.mdd) file using a specified format (see Example 7-1) and define a Table Descriptor or read multiple metadata files zipped together to create multiple Table Descriptors. You can also define a target Table Descriptor manually; see Adding a New Target Table Descriptor.
You can create multiple Table Descriptors by uploading a zip file containing multiple metadata files. The system unzips the file, identifies and reads the metadata files (.mdd extension) and ignores any other files. It uses the metadata information to either create new Table Descriptors or update and synchronize existing Table Descriptors as the case may be.
