Goals for JCC meetings:

  • Capacity for the DAC
  • Data distribution from Archive site to JCC members
  • Staffing efforts required to operate the necessary infrastructure
  • Collaboration on investigations
  • ~6 months small group / focused meetings. Avoid distractions

UK progress on Qserv testing

  • Using real data release (Euclid's ~3TiB)
  • Problems with ingesting data (resolved). Ingesting from empty databases (blank starting point)
  • Functional system available. Comparison to MS SQL instances serving same data.
  • Starting 8 node physical installation. (current installation is virtual)
  • How to efficiently ingest data into Qserv? ascii / binary format? Parallel loading?
  • Need documentation of multi node setup
  • Expect different number of Qserv worker nodes. Estimation of loading time needed.

Calibrated Exposures

  • Likely not a bulk exported product due to capacity requirements
  • Most likely needed to recompute on remote ends

Next meeting in 2 months cadence
