Should be possible to experiment with loading additional databases without affecting S82 data
Working on better file organization for the image data
Looking at following Unknown User (jalt)'s proposal for data immutability (see
RFC-249

Ran into some problems with respect to time stamps / time zones in creating Docker containers (see
DM-8119
-
Getting issue details...STATUS
)
Interpreting logs when containers have a different time zone than the host OS - KTL says that
DM-1203

- Set single time for all project software & common machines Done is meant to be the current policy on log timezones and formatting; if NCSA can now support UTC-only systems, that would be preferable.
Interpretation of time stamps in the database data - KTL says that database columns are meant to be explicit in the schema (usually in the column name itself) as to which time scale they are in (TAI or UTC) and should never be in local time. But while this appears to have been followed in the baseline schema, it doesn't seem to have been written down. MySQL (MariaDB) appears to store TIMESTAMP columns as integers containing YYYYMMDDHHMMSS interpreted as UTC but they appear to ignore leap seconds and do not accept 60 as a seconds value.
Unknown User (jalt): NCSA is very happy to go to uniform UTC time zone settings in production services
Working on getting multiple types of searches attached to dbserv from the UI. Have demonstrated full round trips from the UI to the current temporary dbserv. Really need the actual Qserv service in order to continue to make progress.
These search processors are already running on the PDAC Firefly deployment
Load-balancing server is up and running
Planning to put the DAX services behind the load-balancer as well
Planning to do direct DAX queries from an IPython notebook as a proof-of-concept, with Firefly visualization in the notebook
Have started the creation of the PDAC Firefly application page
Will bring in the IRSA light curve viewer once the images are available
Action items
Igor Gaponenko: change to the Docker container production/configuration procedures in such a way that internal timezone setting of the containers were inherited from their host environment. The implementation of this will be conducted in a context of DM-8119
