When we give {} as key in scan, it gives all of the records in output and when we give {} in dedup, output depends on the keep parameter..

Hi
If you keep {} or any value it sends all the records into the output
Where as in dedup if you keep key as {} and keep unique as parameter then no records will be sent
it treat as single group and no unique values will be fetched
Someone can correct me if im wrong

In case of {} key in scan it will give all the records in case of dedup if you keep it as first it will give first record if you keep it as last it will give last record in case of unique only it will give no records.

For unique only, the output for Dedup will be 0 records. While if you keep it to first or last it will be first or last record of each partition respectively.. While in case of scam it will treat the entire base as one group, or divide the entire base = Number of parttions if the file is partitioned.
