Discussion items
Fine tuned W15 plan
- DM-1034
- check for scalability problems
- spanning multiple file systems
- idea: perhaps always bring data through butler to avoid silly copying of the same data, or bringing data without metadata
- DM-1033
- throw quick prototype early
- Butler work and image archive - Swap assignment: AndyS with Serge
problems with building test program with g++ (GCC) 4.8.3 20140624
- comment out the line that builds that test program, it is an obsolete test and will be removed
- create story under refactoring: "remove code made obsolete by new xrootd port (czar and worker)" (see DM-1145)
publishing on lsst distribution server:
- need write permissions lsstsw
- Fabrice will stop his own distribution server
- useful link related to buildbot: [Triggering a Buildbot Build|https://confluence.lsstcorp.org/display/LDMDG/Triggering+a+Buildbot+Build]
DM-602 (installing without network)
- Fabrice has working draft
Topics for meeting with Monty
- splitting myisam so that we can build it as lightweight library
- proxy
- lua painful
- lua is single-threaded, can't block on calls
- MaxScale and ProxySQL. Both seem lower in maturity than mysqlproxy. In both, the focus is on scalability and load-balancing, and customizability is focused on rewriting queries
- narrow table for objectId, need efficient index, need some updates, 50B rows
- worth trying Aria?
- joint keynote about myisam at percona mysql conf?
- borrowing mysql developer for 2-3 years?
