This Pocketmine-MP plugin removes all the empty chunks from your world, reducing world size and read/writes to disc. Along with reducing cpu usage on world load , improving performance , reducing lag.

• Using in-memory world provider
• Having large maps of skyblock, bedwars, etc gamemodes (void worlds)
• After importing/converting java or pc worlds to bedrock (mc bedrock and java by default saves empty chunks, increasing world size whereas pmmp does not)
• Storing worlds on a remote server

• Took 24.6 secs to convert a world having a total of 10152 chunks out of which 9872 chunks were empty (Remaning chunks: 280) World size reduced from 1.62MB to 265KB

• Took 1.8 secs to convert a world having total 1057 chunks out of which 0 were empty

• Took 15.7mins to convert a world having total 395478 chunks out of which 377748 chunks were empty (Remaning chunks: 17730) World size reduced from 96.8MB to 19MB

• Took 7.47mins to convert a world having total 191794 chunks out of which 191336 chunks were empty (Remaning chunks: 458) World size reduced from 40.5MB to 888KB

Above tests were performed on github codespaces (basic)

Please note this is a cpu intensive process

• Just download the .phar file.
• Upload it to your plugins folder.
• Upload your worlds to the worlds folder
• Edit config.yml to your needs
• Restart the server.
• Wait for worlds to be converted (might take more time depending on world size)
• Check plugin_data/EmptyChunkRemover for your converted worlds

# Configuration Version
config-version: "1.0"

# World names that need to be converted / fixed.
