Interface DeleteFiles

  • All Superinterfaces:
    PendingUpdate<Snapshot>, SnapshotUpdate<DeleteFiles>

    public interface DeleteFiles
extends SnapshotUpdate<DeleteFiles>
    API for deleting files from a table.

    This API accumulates file deletions, produces a new Snapshot of the table, and commits that snapshot as the current.

    When committing, these changes will be applied to the latest table snapshot. Commit conflicts will be resolved by applying the changes to the new latest snapshot and reattempting the commit.

    • Method Detail

      • deleteFile

        DeleteFiles deleteFile​(java.lang.CharSequence path)
        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.

        Parameters:
        path - a fully-qualified file path to remove from the table
        Returns:
        this for method chaining

      • deleteFile

        default DeleteFiles deleteFile​(DataFile file)
        Delete a file tracked by a DataFile from the underlying table.
        Parameters:
        file - a DataFile to remove from the table
        Returns:
        this for method chaining

      • deleteFromRowFilter

        DeleteFiles deleteFromRowFilter​(Expression expr)
        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.

        Parameters:
        expr - an expression on rows in the table
        Returns:
        this for method chaining
        Throws:
        ValidationException - If a file can contain both rows that match and rows that do not

      • caseSensitive

        DeleteFiles caseSensitive​(boolean caseSensitive)
        Enables or disables case sensitive expression binding for methods that accept expressions.
        Parameters:
        caseSensitive - whether expression binding should be case sensitive
        Returns:
        this for method chaining

      • validateFilesExist

        default DeleteFiles validateFilesExist()
        Enables validation that any files that are part of the deletion still exist when committing the operation.
        Returns:
        this for method chaining
