waterlx opened a new issue #751: Add an option to decide whether to delete data files in Catalog.dropTable() URL: https://github.com/apache/incubator-iceberg/issues/751 I would like to propose to modify Catalog.dropTable() to add an option to decide whether to delete data files when dropping the table, like: ``` /** * Drop a table; optionally delete data and metadata files. * <p> * If purge is set to true the implementation should delete all data and metadata files. * * @param identifier a table identifier * @param purge if true, delete all data and metadata files in the table * @param deleteData ignored if purge is false; If purge is true and deleteData is true, delete all data and metadata files in the table; If purge is true and deleteData is false, delete all metadata files while keep all data files; * @return true if the table was dropped, false if the table did not exist */ boolean dropTable(TableIdentifier identifier, boolean purge, boolean deleteData); ```
