How does one do incremnental loading
CHECK OUT THE OPTION, truncate target table option in
sesson==> target properties.
this makes the incremental load.
Scenario - You are trying to load reasonable amount of
rows into the target table, and its taking a helluva lot of
time.What could be the reasons?
use bulk loading in session properties.
use less record as master table in joiner
use filter in first of the mappings
dont use unwanted columns in source qualifier.. better use
SQL overriding.
use dynamic lookup only if in use.
tune your query what ever reads from db.
use partitioning of table if records are huge in number.

Answer
1.We can do incremental loading by clicking on the check box inside Aggrgator T/R.Use filter transformation before Aggrgator to filter out rows and pass only the changed records to the flow.
2.One of the reasons could be the time its taking to build caches.to answer this more details of the maping is required.
