Hello,
Please note that I updated the db spreadsheets few moments ago
and updated years: the spreadsheets used to incorrectly assume
that the first two data releases are in 2013 and the last one
in 2022

Hello all,
Thanks Jacek!
I have updated the LSST CPU Needs spreadsheet (document-2116) with the new
CPU numbers and the corresponding slide in the proposal presentation
(document-2082). Cristina and Arun, please adjust the AC and DAC cost
estimates accordingly for the latest CPU and disk requirements NLT Tuesday
next week. Thanks!

Subject: [LSST-data] database spreadsheets updated
Hello,
I have updated the database storage and diskIO spreadsheets
(Document-1779 and Document-1990).
The main changes in the diskIO spreadsheet include:
- near neighbor query is now using Object table
instead of Source table
- removed "find variable stars close to hot stars" and
adjusted number of other high-volume queries accordingly
- added cpu load
All the changes except the first one were discussed publicly
in the past few months.
The changes helped to significantly decrease the number
of disks and CPUs needed.
The storage spreadsheet contains minor changes,
the sizes are within ~1% difference.
thanks,
Jacek
