Fabrice, Daniel, Douglas, Bill, Jacek
[lots of ad hoc design discussions]
missing in our current draft module diagram
(homework, from Daniel)
- cluster mgr
- configuration
- bootstrapping / static configuration
- geometry/partitioner (many parts need to know it,
it is not only on master, things like replication
management etc need to know on the worker. So,
geometry not master specific
Jacek's input, see:
https://dev.lsstcorp.org/trac/wiki/db/Qserv/Components#ToDiscuss
Daniel+Bill will work on further details of the modules
for the master query execution
- need to define interfaces, state kept, etc...
sessionId --> perhaps call it "userQueryId", or uQueryId instead
deal with authorization/authentication later
topics that might be worth addressing soon
- data loading
- data distribution
- configuration
- worker
- fault tolerance
would be useful to have fault tolerance checklist
- what types of problems does the system have to survive
Next meeting this Thursday, probably no heavy design
discussion, might talk about:
- wishlists
- documentation
- merge engine
