4.  def alterTable(newCatalogTable: DeltaCatalogBaseTable): Unit

   Executes ALTER operation on Delta table.

   Executes ALTER operation on Delta table. Currently, only changing table name and changing/setting table properties is supported using ALTER statement.

   Changing table name: ALTER TABLE sourceTable RENAME TO newSourceTable

   Setting table property: ALTER TABLE sourceTable SET ('userCustomProp'='myVal')

   newCatalogTable

   catalog table with new name and properties defined by ALTER statement.

7.  def createTable(catalogTable: DeltaCatalogBaseTable, ignoreIfExists: Boolean): Unit

   Creates a new table in metastore and _delta_log if not already exists under given table Path.

   Creates a new table in metastore and _delta_log if not already exists under given table Path. The information stored in metastore will contain only catalog path (database.tableName) and connector type. DDL options and table schema will be stored in _delta_log.

   If _delta_log already exists under DDL's table-path option this method will throw an exception if DDL scheme does not match _delta_log schema or DDL options override existing _delta_log table properties or Partition specification defined in PARTITION BY does not match _delta_log partition specification.

   The framework will make sure to call this method with fully validated ResolvedCatalogTable or ResolvedCatalogView.

   catalogTable

   the DeltaCatalogBaseTable with describing new table that should be added to the catalog.

   ignoreIfExists

   specifies behavior when a table or view already exists at the given path: if set to false, it throws a TableAlreadyExistException, if set to true, do nothing.

   Exceptions thrown

   CatalogException in case of any runtime exception

   DatabaseNotExistException if the database in tablePath doesn't exist

   TableAlreadyExistException if table already exists and ignoreIfExists is false

8.  def dropTable(catalogTable: DeltaCatalogBaseTable, ignoreIfExists: Boolean): Unit

   Deletes metastore entry and clears DeltaCatalog cache for given Delta table.

   Deletes metastore entry and clears DeltaCatalog cache for given Delta table.

   By design, we will remove only metastore information during drop table. No filesystem information (for example _delta_log folder) will be removed. However, we have to clear DeltaCatalog's cache for this table.

    Returns a CatalogBaseTable identified by the given DeltaCatalogBaseTable#getCatalogTable(). This method assumes that provided DeltaCatalogBaseTable#getCatalogTable() table already exists in metastore hence no extra metastore checks will be executed.

    Exceptions thrown

    TableNotExistException if the target does not exist

    Checks if _delta_log folder exists for table described by DeltaCatalogBaseTable#getCatalogTable() metastore entry. This method assumes that table exists in metastore thus not execute any checks there.

    returns

    true if _delta_log exists for given DeltaCatalogBaseTable, false if not.
