warmup_single_split_initial_allocation

Error message

warmup_single_split_initial_allocation ({}) must be lower or equal to warmup_memory_budget ({})

What it means

Searcher split-cache warmup validation found that `split_cache.warmup_single_split_initial_allocation` (bytes reserved for one split's warmup) exceeds the total `split_cache.warmup_memory_budget`. A single split's warmup could never fit in the budget, so the configuration is rejected.

Solutions

1. Lower `warmup_single_split_initial_allocation` to at most `warmup_memory_budget`
2. Increase `warmup_memory_budget` to comfortably exceed the per-split allocation

When it happens

Trigger: Thrown at quickwit/quickwit-config/src/node_config/mod.rs:707 when the library encounters an invalid state.
