Hi Marc,
You once explained that the data used by the Perf Schema is all-static,
allocated at startup. What happens if, after startup, a client does
"INSTALL PLUGIN a_plugin;"
and this plugin features your instrumentation?
Will the plugin's instrumented data be properly reported, or ignored?
Does a concurrent SELECT from the Perf Schema risk reading something wrong?
What about UNINSTALL PLUGIN?
Thanks.
