Statement of the week, citing EL (14-1-2025):
"There is nothing that can not be solved, what we are missing is meetings like this."
But the deployment could be at a single high reliable DC, which is easier to maintain.
when we know what we want we can include things in the SLAs to the DCs
more critical is the DBs, important that it is provided by the DC: backups, service, maintenance
questionnaire to the DCs, N. Neyroud made one in 2019, we can already ask for mysql,or mariadb , required by dirac (?), fully open source, questionnaire needs to be redone
is it going to be a shared db service, we can also use a distributed db?
set up the requirements, collect our own knowledge about DBs, needs a dedicated meeting
other systems like SUSS SOSS need to be included as well, they are in design phase we should include them in the discussion
MF (SUSS) already busy with this, is on top of SKAO developments regarding this
first have to agree among ourselves, then afterwards negotiate with DCs
we already have a list of DBs,some are already set: mysql and postgres.
galera clusters are independent, is an issue when eg power down at a DC, then we need backups and agreement with the DCs on accepted downtime
can we have a shared cluster distributed on different dcs?
if Rucio already provides what we need, why do we need to implement it?
BIG question marks about:
we only support restricted queries
