: is it really necessary to run an full import every night ? (these comments are not specific to DIH, they are general opinions)
In my experience if you have a really good "delta" importing strategy, then the only reason you need a full rebuild strategy is in the event of catestrophic failure, or in cases where you may want to modify the schema.xml and reindex. If your delta importing mechanism is effecient enough it can *be* your full reindexing strategy by marking all records as modified. likewise: if your full builds are lightning fast, then you can eliminate some complexity by not bothering with a delta import strategy, and just rebuild on a regular basis. The key: have as much complexity as you need, but no more. -Hoss
