Expected Behavior

  • Eliminating out of memory heap errors on the watchlist and when editing the publisher - with 1.5 million events, the memory demand did not exceed 500MB, previously 4GB would not be enough;
  • Improved application stability - +250 000 events does not lead to performance issues and crash; (the previous limit was about 5,000 events)
  • Faster up the loading for +250 000 events:
    Context Data Source - Data Points list, and Data Source Events list;
    Context Data Point - Data Point Details;
    Context Publisher - Edit Publisher;
    Context Graphical View - Alarm List Component;
    Context Alarms;
    Context Watchlists

Solution

  • Disabling the old cache - env.properties, same configuration, you can go back;
  • Added a limit for Pending Events - can be configured in runtime in system settings, on old and new ui;
  • Fixed sorting by active timestamp for Pending Events;
