Class StreamingDelete

    • Method Detail

      • operation

        protected java.lang.String operation()
        A string that describes the action that produced the new snapshot.
        Returns:
        a string operation

      • deleteFile

        public StreamingDelete deleteFile​(java.lang.CharSequence path)
        Description copied from interface: DeleteFiles
        Delete a file path from the underlying table.

        To remove a file from the table, this path must equal a path in the table's metadata. Paths that are different but equivalent will not be removed. For example, file:/path/file.avro is equivalent to file:///path/file.avro, but would not remove the latter path from the table.

        Specified by:
        deleteFile in interface DeleteFiles
        Parameters:
        path - a fully-qualified file path to remove from the table
        Returns:
        this for method chaining

      • deleteFile

        public StreamingDelete deleteFile​(DataFile file)
        Description copied from interface: DeleteFiles
        Delete a file tracked by a DataFile from the underlying table.
        Specified by:
        deleteFile in interface DeleteFiles
        Parameters:
        file - a DataFile to remove from the table
        Returns:
        this for method chaining

      • deleteFromRowFilter

        public StreamingDelete deleteFromRowFilter​(Expression expr)
        Description copied from interface: DeleteFiles
        Delete files that match an Expression on data rows from the table.

        A file is selected to be deleted by the expression if it could contain any rows that match the expression (candidate files are selected using an inclusive projection). These candidate files are deleted if all of the rows in the file must match the expression (the partition data matches the expression's Projections.strict(PartitionSpec) strict projection}). This guarantees that files are deleted if and only if all rows in the file must match the expression.

        Files that may contain some rows that match the expression and some rows that do not will result in a ValidationException.

        Specified by:
        deleteFromRowFilter in interface DeleteFiles
        Parameters:
        expr - an expression on rows in the table
        Returns:
        this for method chaining

        Set a summary property in the snapshot produced by this update.
        Parameters:

        value - a String property value
        Returns:
