> To avoid disk I/O potential competition between GC and broker threads, GC logs are placed into {{/dev/shm}}. This is a valid concern, but I propose more consideration to be done to situations when the system crashes (and, as a result, in-memory logs disappear).
> Long-term logging is essential for analysis of the brokers' performance.
