     31The bulk of my work this week was on code to speed-up the ingestion of DVO data into MySQL while not breaking the existing mechanism of using the C-API for reading DVO data on an exposure-by-exposure basis, as this will still be more efficient for parts of the sky with thin coverage. One big speed-up came from removing the need for 'SOURCE_ID', which I had been carrying unnecessarily per detection in my MySQL database.
     32
     33The other development task was figuring out how to queue available data to load to PSPS by region on the sky based on the ratio of exposures I have to load and the size on disk of the corresponding DVO FITS files. An algorithm is required to decide when it is appropriate to load on-the-fly, exposure-by-exposure, and when it is more efficient to pre-ingest a region of DVO. This becomes especially confusing as I have a multi-client system where clients, thus far, worked independently of one another. This will have to change.
