Structure DFU Cache

Structure DFU Cache 1.2.0

Features & Improvements

• TOML configuration: Added config/structure_dfu_cache.toml (loaded on game startup; restart required after editing).
• Configurable processing limits:
  • maxDecodedNbtMiB (default 1024): Positive integer in MiB tracking the NBT decoder's accounting of in-memory NBT objects and allocation overhead during processing (this does not measure total DFU memory).
  • maxCompressedResourceMiB (default 64): Positive integer in MiB setting the limit for compressed structure resource size.
• Concurrency & memory estimation: Worker concurrency is budgeted based on available heap after deducting resident memory and a 2 GiB reserve, estimating total DFU memory at roughly 4x maxDecodedNbtMiB per worker (capped at 4 threads, leaving 1 CPU core free when more than 1 core is available). Higher quota values reduce worker concurrency to allocate more memory headroom.
• Fallback behavior: Structures exceeding maxCompressedResourceMiB bypass startup pre-processing and are handed back to vanilla reading. Structures exceeding maxDecodedNbtMiB or failing conversion cache the raw compressed bytes as unoptimized resources to retry during future load or reload.
