With this in mind, I will expect a load pattern like this
Every extract from the source will be a full load
Every load in terms of records, will be equal to last load + new records – deleted records
80-90 % of the extracted records will already exist in the valid table instance
Every load will be incrementally larger than the previous load, as more records are added to the sourceThinking
