Very recently as part of our library for example we've set it up that on enable it will grab data from a db and initialise an "sqlTable" class which is essentially a cache that periodically updated back to the dB (every few mins) the big changes.
Or if ur not a masochist, learn redis and implement a duel system of SQL and redis
echo basalt
A database is a piece of software written with the objective of managing data. It provides an easy solution to manage your data at a large scale, across multiple machines.
Depending on the type of database (SQL vs NoSQL), data can be stored in different ways:
-
In an SQL database, the data is stored in tables which consist of columns you write ("PlayerID is a variable character array of length 36"), which are then indexed by the DBMS (Database Management system, such as MySQL for example) so you can do queries like
SELECT money FROM player_data WHERE PlayerId = '...'; -
In a NoSQL database (Let's say mongo), the data is stored in documents, that look like "json" files (In practice it's actually bson, a binary version of json), where each document has an internal ID and is also indexed for queries.
To operate a DBMS, you must establish a connection with it. Most DBMS software is designed to handle multiple connections from multiple sources, and have safety checks such as internal locking and read-only views to deal with concurrent requests, so things don't become desynchronized.
Don't forget that your DBMS instance isn't made of iron, and you want to cause as little load on it as possible, so you need to have a balance between keeping data in cache on your program (plugin), and hitting your database with queries.
Once you achieve a huge load, it's important to shard your database, which means that segments of it are kept in separate instances and it all acts as one, with shared indexes. This allows you to hit different instances at the same and retain functionality while spreading the load.

If there are 1000s of data in a haspmap, how much ram will it consume?
prime epoch
and how much ram and cpu am i need for this ?
not much, its mostly hard drive space you need. If youre using a server hosting provider then they should have MySQL support already
prime epoch
If there are 1000s of data in a haspmap, how much ram will it consume?
depends on teh data being stored
livid dove
If there are 1000s of data in a haspmap, how much ram will it consume?
It's a very varied answer unfortunately.
It will 100% depend on the data being stored. E.g storing 1000 into would be be less ram than storing 1000 strings that are all 3 sentences long

If you understand java's memory structure, you'll understand that literally everything (with the exception of primitives) is pass-by-reference and not pass-by-value. When you're storing an object in a collection, you're storing the reference of that object in the collection and there's a sort of "reference table" that assigns references to objects in the JVM.

What I'm saying is that when you're dealing with players, there's usually only 1 instance of each online player, and the same reference is being passed around EVERYWHERE, including your map
young knoll
Because they are both just a refrence to an object
livid dove
You said you can save memory by storing UUID over player
I mean preventing a memory leak is saving ram. Check mate atheists
young knoll
And refrences are all the same size
prime epoch
Because they are both just a refrence to an object
oh i see
alright i see my mistake my bad
echo basalt
When you put players in a map however, you're still holding a reference in that map which prevents the object from being garbage-collected. When the player then leaves and rejoins, the old instance is not GC'd because it's reachable by your map, but the new instance is also put in your map which results in a memory leak
young knoll
Unless you use a weak map

livid dove
How does it work? Can you make an example?
Of course. That image is a single table.
It is controlled using an SQL table manager:
Each "table" added to the manager is a cache of the table that updates every X ammount of time (config defined) that allows for easy calling of data from the table.
If a row is added, updated, removed etc, every X ammount of time the SQL is also auto updated.
If, onEnable, the table is initialised, and a check of the database shows the table does not exist, it will create it as per the fields of the Class.
In fact

Decent, I usually just have a main table class and do a lot of manual logic
Problem is

the filtered param type is also used for automatic filtering and casting

Am i being dense? Whats the problem
echo basalt
So the parser is broken down into 4 elements:
- Literals
- Parameters
- Tags
- List parameters
Literals are just 1:1 text
Parameters have a type, and if they're optional and don't match the type you skip ahead to the next element
Tags are like optional literals
And list parameters are like parameters except that if you do have a match, you match until:
- The next element (Everything has priority over list parameters)
- The list's parameter type no longer matches the input
And I just did this with a big ass for loop
And honestly I want to rewrite it into an actual parser with tokens

I don't think any changes were made to that event

But from what I saw, there isn't differences for the levitation handling
wet breach
So the issue is when you cancel the event they continue to go up?
dull atlas
So the issue is when you cancel the event they continue to go up?
I don't cancel the event, I simply modify the X and Z position of the destination, yet it affects the levitation velocity
As alternative solution, I will simply add the levitation velocity in my event (even tho it's not great/optimal)
wet breach
So when the player moves you are changing where they are moving to?
If that is the case that makes sense in why velocity is affected
This isnt really a bug
Rather the server recalculating their trajectory and time it should get there
By setting for example their position further then the server says well for that to be possible they need to be going this fast or this slow lol
Its not like teleporting
wet breach
As alternative solution, I will simply add the levitation velocity in my event (...
This would be the correct action. You need to factor in their new velocity due to the sudden change in position
dull atlas
If that is the case that makes sense in why velocity is affected
It makes sense that when you change the X/Z destination, that the X/Z velocity is affected (due to shorter/longer distance).
But how is it affecting vertically?
wet breach
Well idk if while having levitation you can hover across the ground moving freely. If not the only free movement is on the y
dull atlas
Well in vanilla MC, you can move horizontally while having the levitation effect
Which I am trying to avoid by simply making the player levitate upwards only
young knoll
You can try setting their walk speed to 0
wet breach
Then i would cancel the move event if x and z changed by 0.5
dull atlas
Then i would cancel the move event if x and z changed by 0.5
I am not quite sure to understand your sentence
wet breach
Move event?
Just cancel it if x and z changed by 0.5
Not sure what is difficult to understand here
dull atlas
By canceling it, you cancel the Y velocity
young knoll
Does setting fly speed work?
wet breach
By canceling it, you cancel the Y velocity
Sure, just reset the y velocity
Not sure why that would be so hard
dull atlas
Sure, just reset the y velocity
That would break the levitation effect
If I cancel it
dull atlas
Does setting fly speed work?
Not sure but I can try, I think fly speed only affects when you fly, rather than hovering
wet breach
It shouldnt if velocity is reset back to being upwards
dull atlas
As alternative solution, I will simply add the levitation velocity in my event (...
Yes, that's what I said here, no?
wet breach
Like they are not going to fall out of the sky unless you dont set the velocity of course. All you should do is check the move event and see if x and z changed by a certain amount. If it has, cancel the event reset their velocity
dull atlas
I'll try to calculate the levitation velocity while revoking the horizontal ones
wet breach
You dont need to recalculate anything if you just cancel the event
echo basalt
Is there a way to know what chunks a player sees?
Or what players can see a chunk
Might be something about the chunk ticket system
dull atlas
Like they are not going to fall out of the sky unless you dont set the velocity ...
Why would I cancel the event? It would lock player Yaw and Pitch
wet breach
Is there a way to know what chunks a player sees?
Believe you can do this by seeing the amount of chunks the client requests?
echo basalt
Probably
wet breach
Why would I cancel the event? It would lock player Yaw and Pitch
You never specified this as a requirement
dull atlas
You never specified this as a requirement
π
wet breach
Anyways their view only resets when the event is cancelled and the event should be cancelled when x and z changes
So it wouldnt be all the time
dull atlas
Same way I never specified that I don't want the player to die or other things.
I just don't see why would you delete a variable, just to recode the same one, when you can just modifiy a variable via get/set
wet breach
What you should do then, is set their velocity to 0 when you change their position
Then set the velocity back to upwards
dull atlas
I have no ideas if you are trolling or if you are genuily serious
But that sounds like a really bad idea, sorry
wet breach
Ok then i wont help further.
compact haven
heβs being serious lol
I have no idea what this issue is, but frost doesnβt joke
dull atlas
I will simply add levitation velocity (0.9blocks/s) to my event while preventing the x/z variables to change
compact haven
pretty sure heβs incapable of such
wet breach
Spigots code on the other hand there isnt a flaw with it though
Just you have a unique requirement that doesnt fit the api
dull atlas
Indeed
I don't really think it's a flaw, just my case is very unique and wasn't taken in account for the Event
wet breach
Well resetting the velocity should do the trick for you
Because then it removes any guessing
Its basically like normalizing
dull atlas
But math/code wise, it's far simplier (logically) to revoke X and Z changes in the movement, while adding the predicted Y movement needed for the levitation.
Instead of rewritting the whole Location after canceling an event
wet breach
Well you said it was causing velocity to be added everytime to the y
You could just nullify that velocity by resetting it.
dull atlas
Hi, how can I freeze player movement on the horizontal axis (x and z) without af...
Nope, the velocity is frozen a bit
But I'll try to reset the velocity
rather than canceling the event
wet breach
I was continuing with you not cancelling the event
If you dont cancel the event just nullify the velocity by resetting back to known values
dull atlas
Yeah
wet breach
And then add velocity if its needed right after
dull atlas
Mhm, hopefully this won't alter the levitation
wet breach
It shouldnt, but this just removes a lot of guessing to predict unexpected velocities lol
dull atlas
Tried and, it works halfway. The player moves simply slower horizontally (altho the levitation works fine now)
It's like if the velocity (event) is reset in specific frames, but in between them the player can move a little bit
wet breach
Well better then nothing. And see wasnt such a crazy idea after all 
dull atlas
xD
wet breach
I wonder if its because of the client
dull atlas
Well I will revert my code like before, and will do some testing to find a good way to remove the freeze of levitation by adding some Y velocity
dull atlas
I wonder if its because of the client
It could be
wet breach
If its due to the client you would need to reset velocity a couple of times to get the client to register that lol
wet breach
Client uses prediction with movement and over rules the server in regards to where it wants the player to move
So even though the server recognizes you want the player to stop the client could send another position packet and thus player moving again
Always fun to battle the client

Ah yes, forgot that in Minecraft it's the way around than most video games xDD but yes makes sense

Would I need to make a loop or idk to make it work?
wet breach
Idk you could try that or see if resetting velcity a couple times spaced by a tick or two works
dull atlas
mhm
If could maybe give negative velocity depending on the destination velocity? altho it might not be great
wet breach
Really wished mojang would let the server dictate movements and not the client
wet breach
Well the hacks are actually easy to curtail
Most people dont because they want hardcore pvp
Basically how you handle them especially something like reach is you would set a lower value for the reach. This way if they use a hack they can only ever achieve normal values
Which makes detection super easy after that
But yeah it is the reason those things can be done more easily

imho you should make a thread covering multithreaded workdist for operations like FAWE block placement etc which must be sync
I personally would like to see and in detph coverage of that kinda workdist vs an overview of the logic

you know what fawe does, do you?

but its still good to understand meaning of workload distributions
Distributing a workload over multiple ticks is splitting a synchronous computation into an asynchronous one.

Pretty much the same i do in this thread

Nope no clue but you seem to have a good grasp which is why I made the reccomendation I can't write it I don't know wtf is going on

if they use workload distribution it doesnt mean they have same code
try {
asyncCatcher = Class.forName("org.spigotmc.AsyncCatcher").getDeclaredField("enabled");
asyncCatcher.setAccessible(true);
asyncCatcher.setBoolean(asyncCatcher, true);
} catch (Throwable ignored) {
}
thats part of fawe's code

Quick question. I know the best practices but I'm curious why they're best practices.
So obviously, use SQL connection pooling because it's slow to open a new connection for each transaction.
But why not just have a single connection open for the whole duration of the program?
lost matrix
on github or spigot
?!
lunar wigeon
well you have repo on github and thread on spigot
lost matrix
Quick question. I know the best practices but I'm curious *why* they're best pra...
Because you should close connections after you are done using them.
Sometimes there might be an error while doing transactions which will
drop the connection. There is also the possibility of multiple threads
wanting to connect to your DB. And all of them waiting for a single connection
is very questionable.
lavish hemlock
But why should you close connections after you're done with them?
lunar wigeon
also using NMS you can place block way faster
lavish hemlock
The other parts make sense though.
lost matrix
well you have repo on github and thread on spigot
What are you talking about? There is no runtime check i can do to gain the exact server tick start.
lavish hemlock
also using NMS you can place block way faster
NMS is discouraged due to its instability, but nobody's stopping you from using it.

reminds me i wanted to PR a ServerTickEvent w two possible "stages", START, and END, like
public class ServerTickEvent extends Event {
private final Stage stage;
public ServerTickEvent(Stage stage) {
this.stage = stage;
}
public Stage getStage() {
return stage;
}
public enum Stage {
START, END
}
}```Oh Fabric has something like that.
remote swallow

as long as the servers event manager isnt dogshit it shouldnt be an issue

Well, you're probably already calling a shit ton of events every second anyway
And on Paper this is negligible

So I can only imagine what that looks like on the server side
lost matrix
But why should you close connections after you're done with them?
Same reason why you dont have open, dangling file pointers: Resource management.
There are only so many open connections you can have. So best practice is:
Use a pool
Close your connections
Dont worry about creating them and just ask the pool to handle it
buoyant viper
1.9+ tried? to optimize this iirc by sending fewer position packets if a player hasnt moved
but i think it still spams hard p sure

lavish hemlock
I'm not arguing, mind you. I'm just trying to understand why it is that it's so vital to close a connection immediately after you're done with a single transaction.
I can understand the multithreading aspect though
lost matrix
Also mem mapped files dont keep file pointers open in the traditional sense. It lets the os
map files into virtual memory. Big difference.
lavish hemlock
That's true.
Most of the time I keep resources active for however long I need them and then when everything's all done I shut 'em down lol

But good question. Its been a long time since manually handling connections myself so i just took it as a given to close them.

application crashes -> resources get hogged
lunar wigeon
@lost matrix you may implement system to your queue that reduces queue ticks per second depending on tick responds (how fast is the code ran)
or just use multithreading somewhere
lavish hemlock
Not entirely true, the kernel will close most resources, i.e. sockets and file pointers, and I thiiink that should apply to SQL connections since hopefully the server would be able to detect a closed socket...?

For a task like setting a large area of blocks, fork/join sounds perfect since you cut down the large task into smaller tasks.
But I'm not sure how compatible Bukkit is with just regular ol' Java concurrency lol
lost matrix
Yeah that might work. But that sounds very specifc to me.
Its just a matter if introducing a tick counter and checking with a modulo
which is defined by the current tps. Limiting the millis per tick should be enought

The thread kind of is about a fork/join where you fork on ticks but stay on the same thread.
Not sure how this analogy holds up.
