Chunk processor

Disclaimer

This is a new feature, not a magical solution to all your problems. The chunk processor isn't perfect, and it is your fault if it fails to mitigate crashes / corrupt chunks and the likes (Although feel free to create a ticket if you think it's something it could prevent in future).

It is however very efficient, and will hardly leave a footprint when there are no chunks to process.

Overview

The chunk processor will process chunks before they are saved / loaded from disk. It is lightweight at the moment with the following capabilities:

• Clear entities if a dangerous amount is detected
• Clear blockstates if a dangerous amount is detected

The purpose of the processor is to:

• Decrease server lag
• Prevent potentially dangerous chunks being saved / loaded from disk
• Prevent repeated server crashes from dangerous chunks

The usual causes of dangerous chunks are:

• People abusing WorldEdit
• People abusing VoxelSniper
• Any other tool you have that can be used to spam entites / blocks

Configuration

Configuration is done through the settings.yml

Enabling

chunk-processor:
// If the processor is enabled
  enabled: true
/// The maximum number of entities required in a chunk before it is deemed a source of lag
  max-entities: 512
// The maximum number of blockstates allowed per chunk
  max-blockstates: 4096
