Combines results from a resumed run with new results from continued
execution. Duplicate task rows must be identical or an integrity error
is raised.
Usage
merge_results(prior_results, new_results)
Arguments
- prior_results
Data frame of results from checkpoint.
- new_results
Data frame of results from new execution.
Value
Combined data frame with unique task_id values.
Details
If both inputs are NULL or empty, returns NULL. If only one input
has data, returns that input. Otherwise, removes any task_ids from
prior_results that appear in new_results, then combines.
