RE: What is meant by source is changing incrementally?
I think, source is changing incrementally means new rows are getting inserted into the source. For example, If a source on day1 has 10 records; then on day2, 5 new records got added along with the previous day's 10 records, so total 15 records come on day2; lets assume 7 reocrds got added on day3, then there will be total 22 records coming on day3; and so on. In nutshell, the previous day's data remain unchanged and new data gets inserted in the source.
