| Subj: || || Loading Back Dated Data |
| From: || || Brian Rampersad |
Just a general question about how handle back dated data. Currently we receive data from stores for as much as 1 week to 2 weeks ago.
Upon loading this data, we will need to rebuild some aggregations. My questions is, when rebuilding aggregations, do most people 1) delete
and rebuild or 2) do math and just update the aggregations with the delta information?
