I've been mentioning high level spreadsheet with
long term plan. It is in docushare, LDM-240, see:
https://docushare.lsstcorp.org/docushare/dsweb/Get/LDM-240/LDM-240%2020141118-outlined.xlsx
rows 40-48 are in particular relevant for us.
From qserv perspective, this is what we are on a hook to do in FY 15
-----
Rewrite build and installation scripts and test harness
Evaluate alternative systems and components
Begin rewrite and restructuring of master, worker, and metadata server
Rewrite master and worker and metadata server to support:
Creation and removal of distributed databases
Creation and loading of prepartitioned distributed tables
Initial version of query aborting
Implement initial query types
All of the above robust to user errors, crash-free, and fault-tolerant
----
Also, have a look at KPIs, we promised to demonstrate:
LV query rate simult. queries qserv 50
LV query response time seconds qserv 18
HV shared scan duration hours qserv 24
HV simultaneous queries queries qserv 6
We HAVE TO demonstrate the KPIs by 9/30/2015
