> Test TableDdlIntegrationTest#alterTableLogging is rare flaky cause
> disco-notifier and user threads are not syncronized, I can`t reproduce it
> locally but it can be reproduced by simple sleep hack like :
> CacheGroupDescriptor#walEnabled(boolean) ->
> {noformat}
> public void walEnabled(boolean walEnabled) {
> try {
> Thread.sleep(100);
> }
> catch (InterruptedException e) {
> throw new RuntimeException(e);
> }
> this.walEnabled = walEnabled;
> }
> {noformat}
