when load type is selected as bulk or normal in session level ?let me know the internal process and give me an example?
Answer
For History Load, generally the data is bulk loaded because the cost of indexes on the table is skipped when bulk loading is done as indexes on the target table are not allowed for bulk load.Once the data is loaded then the indexes are created. This way we could load the data into the target much faster.Also bulk load would not write the rows in the roll back segment.The time taken to write into roll back segment is also saved.Hence performance improved.
