CWG13 regular bi-weekly meeting.

Participants: Charis, Barth, Lazaros, Tom, Vasco, Markus, Alexander, Peter

Remote participants: Alexey, Ivana, Matthias

1. DDS topology editor

  • Tests: the topologies created by the the editor were tested and worked successfully;
  • Documentation: Do we need more? We probably should add "Help" button;
  • Installation: the editor is installed locally;
  • Code: it is in GitHub, will be merged in DDS;
  • We would need a link to a DB or repository, where we keep the existing topologies. Alexey will provide a solution for this request.
  • If you do "refresh", everything is lost, but we are implementing a local storage.

2. Key-value

  • The latency is measured for one query;
  • The number of hosts is 15 on the same cluster. The latency includes the connection time. The startup time is excluded. We are considering the burn-in/burn-out period.
  • Is there any connectors for ALFA? They are not yet integrated, the work is ongoing;
  • We should enlarge the scope to single values and big objects;
  • MySQL may have better performance for key-value storage;
  • Load-balance may be bottleneck, but multiple instances mey help;
  • Do we have onsite access to the DB?
  • We should use for the tests reference data from the existing ODB, not random data;
  • We have to define the standard use cases.
There are minutes attached to this event. Show them.
