Hi
By accident I noticed that when I configure a LevelDB aggregator
persistence with completionSize = 1 (yes I know, this is kind of an
aggregator that does not aggregate), I get the stacktrace below on every
message.
As soon as I set a completionSize > 1, everything runs fine.
I guess this is a bug, since it worked fine with the old HawtDB repository.
If completionSize = 1 is totally useless it would be better to throw an
explicit error when starting the context.
Should I create a Jira issue for this?
Thanks
Stephan
