Method Detail

self

protected RewritePositionDeleteFilesSparkAction self()

filter

public RewritePositionDeleteFilesSparkAction filter(Expression expression)

Description copied from interface: RewritePositionDeleteFiles

A filter for finding deletes to rewrite.

The filter will be converted to a partition filter with an inclusive projection. Any file that may contain rows matching this filter will be used by the action. The matching delete files will be rewritten.

Specified by:

filter in interface RewritePositionDeleteFiles

Parameters:

expression - An iceberg expression used to find deletes.

Returns:

this for method chaining

execute

public RewritePositionDeleteFiles.Result execute()

Description copied from interface: Action

Executes this action.

Specified by:

execute in interface Action<RewritePositionDeleteFiles,RewritePositionDeleteFiles.Result>

Returns:

the result of this action
