Discussion items
Large scale test
- data loaded
- need simple statistics, like size of data loaded
- Fabrice looking into ELK (https://www.elastic.co/webinars/elk-stack-devops-environment)
- Fabrice backing up data
- problems with rebuilding stack on the build node at in2p3
- eups uses max # of cores (it worked with 4 and 8, with 16 it is much harder to rebuild the stack)
Connections
- hardcoded limits in qserv (per worker): 32 limit for scanScheduler, 4 for GroupScheduler
- Fabrice sees no connection leak on the worker, (except on SL7)
- created story DM-2713 to check for connection leaks in integration tests
Multi-node tests prep
- Vaikunth working on loader-related issues for case 4 and 5
2605 (packaging flask dependencies)
- non blocker. Slowly, over the course of the next two months or so
1674 (data ingest)
- starting, but connection/timing problems higher priority
init.d vs systemd
- latest distros, like centOS 7.1 rely on systemd instead of init.d
- too fresh for us
- install special compatibility packages
We are mixing boost and std
- created DM-2711, DM-2712
Shared memory implementation
- ok to restrict to 2 GB
