getPrefetchedRow

public Row getPrefetchedRow(DecoratedKey key,
                            Clustering clustering)

Returns the prefetched row with the already performed modifications.

If no modification have yet been performed this method will return the fetched row or null if the row does not exist. If some modifications (updates or deletions) have already been done the row returned will be the result of the merge of the fetched row and of the pending mutations.

Parameters:

key - the partition key

clustering - the row clustering

Returns:

the prefetched row with the already performed modifications
