What is the difference between normal and bulk loading?
Which one is recommended?
Answer / rakesh
The main difference between normal and bulk load is, in normal load Informatica repository service create logs and in bulk load log is not being created. That is the reason bulk load loads the data fast and if anything goes wrong the data can not be recovered. But in normal load since the log is created the lost data can be recovered.
By configuring session to Bulk loading we cannot do 'session recovery' when it get failed whereas in normal loading we can easily do session recovery.
Note:In normal load Informatica creates logs record by record in database level and in bulk mode it will not create detail log. By avoiding that detail writing in bulk mode improve performance.
Note:If there are indexes and constraints in the table, you cannot use Bulk Load
You can drop/disable those indexes/constraints (pre session ) , then load the data (use Bulk Load) , and then create/enable the indexes/constraints (post session )
