I'm looking for a way to change a large amount of blocks (~2M BPS) quickly and with as little lag as possible. I found this thread but it's pretty outdated (2 years is an eternity in Mojang time, LooL). I should mention that the persistence of these changes (i.e. them being saved to memory when the server shuts down) is NOT essential (maybe this will help the process?). On the other hand, I DO want the blocks to have light calculated and they should actually exist (i.e. not just sending packets to show them to players). Is such a thing possible? And if not, then how about something slower but that's still faster than the regular Spigot API Block#setType? Thanks in advance!
