thank you for you very thoughtfull insight, but datapacks can only get as performence friendly as they can before you need to convert it to a plugin.



the reason being is NBT tags, name tags and custom enetity triggers and UUID's are all fairly different but all fall under the exception that they put stress on ticks.



for example if you had a data pack checking for items to clear lag, checking all entities at once can cause not so noticeable but a small amount of lag, and then adding complex variables and checks using the MCFUNCTION will only go so far.


the limitation of a datapack is dependant on its purpose, for singleplayer datapacks, simple UI's , Custom GUI's and simeple function or ONE BLOCK function are okay.



but when you get down to heavy performing tasks which requires alot of itteration of functions will stress out the game, thats when you can switch to a plugin.





plugins allow libraries which boost performence by a method called "reflection", also commonly known in other forms in games such as .dll files (dynamic link libraries) this takes a load of the games engine, and we all know that java isnt the best perofming engine out there but with .APIs in plugins we can use it with servers that directly modify NBT's , which is what most anti-lag projects are made on.



the idea is the scope of your project, my pack is deisnged for singleplayer giggles, nothing serious but for bigger scopes like custom GUI's , interfacing, RNG loot crates and other similar information systems like that, plugins provide better support and is more aimed at small servers for friends that run on spigot or paper or craft bukkit.



i do appreciate the advice on datapacks about relasing when something isnt done but do keep in mind that projects do have a percentage completed, but between making minecraft mods, plugins, datapacks and other various projects out side the scope of minecraft, i only get to release things here and there.



also remeber stay proffesional when providing constructive criticism , it helps to convey your intentions more clearly, thank you.
