stageRewrite

public void stageRewrite(Table table,
                         java.lang.String fileSetId,
                         java.util.Set<F> newFiles)

Called to persist the output of a rewrite action for a specific group. Since the write is done via a Spark Datasource, we have to propagate the result through this side-effect call.

Parameters:

table - table where the rewrite is occurring

fileSetId - the id used to identify the source set of files being rewritten

newFiles - the new files which have been written

fetchNewFiles

public java.util.Set<F> fetchNewFiles(Table table,
                                      java.lang.String fileSetId)

clearRewrite

public void clearRewrite(Table table,
                         java.lang.String fileSetId)

fetchSetIds
