The settings related to memory size don't work

[kamikyo]

Describe the bug

I continuously write data to Garnet, primarily with three keys: two sorted sets and one string. Each time, I write 5000 entries, approximately 1 to 2 MB. Garnet's memory keeps increasing over time. As long as I keep writing data, the memory growth will not stop.

Steps to reproduce the bug

garnet server's code:

public static void Main(string[] args)
{
    try
    {
        var factory = LoggerFactory.Create(builder =>
        {
            builder.AddConsole(options =>
            {
                options.LogToStandardErrorThreshold = LogLevel.Trace;
            });
        });
        using var server = new GarnetServer(args, factory);
        server.Start();
        Thread.Sleep(Timeout.Infinite);
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Unable to initialize server due to exception: {ex.Message}");
    }
}

the parameters I specified are:
--port 7010 --index "256m" --index-max-size "512m" --obj-index-max-size "512m" --memory "1g" --recover true --compaction-type "Scan" --checkpointdir "data" --storage-tier true

Expected behavior

I expect the memory to stabilize after reaching a certain limit.

IDE

OS version

windows 10

Additional context

After each execution of the save command, memory usage increases by 200-300 MB.

Can you provide a sample client app as well? Try compaction type of Lookup.

If you are adding new entries in the sorted set, the total memory is expected to grow.

Also, it might be GC uncollected memory - try issuing the GC collection (FORCEGC) using the remote client command line.

The code for the garnet server is as described above. It is a console application(GarnetSample.csproj), and after publishing, it generates an executable file named GarnetSample.exe.
Server's start command:
GarnetSample.exe --port 7010 --index "256m" --index-max-size "512m" --obj-index-max-size "512m" --memory "1g" --recover true --compaction-type "Scan" --checkpointdir "data" --storage-tier true

Client project is DataCreator.csproj.It writes 5,000 records to the garnet server every 3 seconds.
The code repository is located at: https://github.com/kamikyo/garnetdemo

Does the problem persist if you use CompactionType of Lookup?
