Stefan Miklosovic commented on CASSANDRA-13460: ----------------------------------------------- Hi [~spod], do you plan to work on this? I have WIP branch here (1) which is fetching events from stores and it displays them in vtable. We plan to also introduce a helper (mutable) vtable once CASSANDRA-16806 is in via which one might enable / disable events conveniently from CQL shell. If we want to survive reboot, I plan to cover that by implementing Chronicle Queues impl, same way as it was done for FQL / Audit but that I want to cover in a separate ticket.
