But which set of 20 queries? Not all users will want to access the tables in the same way. However, there are clear patterns of queries that are common to all users and we have designed to implement them.
This is an area where our team has spent a great deal of effort. There are any possibilities available and it’s unclear which is the best. We’ve decided on a model with objects held in the main data base and detections and copies of some smaller tables in the slices. OK, then how do you choose to partition? What RAID model?
This is a second area that has involved a great deal of design effort. In SDSS much of the work flow monitoring and error handling occurred in the loading phase – but the PS1 ODM will be loading all the time. We expect the most potential problems in the load/merge process!We’re taking a Sunny, Sticky, and Cloudy day approach to the testing and error handling implementation. Ultimately real data will define the Rainy day case – hopefully it won’t be a Cat 5 hurricane!
