pub async fn export_records_to_files( &self, table_name: String, filepath: String, ) -> Result<ExportRecordsToFilesResponse, KineticaError>
Export records from table
Export records from a table to files. All tables can be exported, in full or partial (see columns_to_export and columns_to_skip). Additional filtering can be applied when using export table with expression through SQL. Default destination is KIFS, though other storage types (Azure, S3, GCS, and HDFS) are supported through datasink_name; see /create/datasink.
Server’s local file system is not supported. Default file format is delimited text. See options for different file types and different options for each file type. Table is saved to a single file if within max file size limits (may vary depending on datasink type). If not, then table is split into multiple files; these may be smaller than the max size limit.
All filenames created are returned in the response.
table_name- The name of the table whose records are to be exported.filepath- Path to data export target. Iffilepathhas a file extension, it is read as the name of a file. Iffilepathis a directory, then the source table name with a random UUID appended will be used as the name of each exported file, all written to that directory. If filepath is a filename, then all exported files will have a random UUID appended to the given name. In either case, the target directory specified or implied must exist. The names of all exported files are returned in the response.
