Mnesia: Intensive Use Table

Question

When I receive a message like this:

** WARNING ** Mnesia is overloaded: {dump_log, write_threshold} 

What is the famous approach that is used intensively in the table ? What debugging do I need to do?

Thanks.

An interesting post on StreamHacker on the topic:

One suggestion in this article is to switch to synchronous recording, but I'm not sure if this is such a good general answer. This will certainly change your scaling characteristics, so don't skip the technique or measure changes.

However, both dc_dump_limit and dump_log_write_threshold are good settings for playback. The default values ​​are somewhat overly sensitive.
