Keywords: DataAccWG
Hi,
Reminder: we have a DataAccWG telecon tomorrow at 11:00 PST.
Phone number: 866 330 1200
passcode: 300 2363
Fairly packed agenda this time:
1) disk space requirements
- what is still missing in our estimates
(SDSS: 300 million of 2kB records --> 600GB.
That is the size of PhotoObj, but the whole
db DR4 is 1.8TB due to indexes, spectroscopic
db, usnob, First, 2Mass, Stetson. Then there
is freespace, tempspace)
2) base camp db architecture
- I/O needed for joining Ingest Tables with
pre-cached archived data
- joining remote tables
3) implementing db software for DC1
(Data Ingest Service, Data Ingest Converter,
who is doing what and when?)
4) missing Data Access use cases
- Querying use case (still in very primitive stage)
- Admin use cases (e.g. backup, dealing with hot spots)
