Struct TierConfig 

pub struct TierConfig {
    pub root_folder: PathBuf,
    pub partition_granularity: PartitionGranularity,
    pub hold: u32,
    pub gather: u32,
    pub max_open_writers: Option<usize>,
}

Fields

root_folder: PathBuf

partition_granularity: PartitionGranularity

hold: u32

Number of partitions to hold before ETL moves data out.

gather: u32

Number of partitions to gather (move out) at once.

max_open_writers: Option<usize>

Per-tier cap on open BufWriter file handles. Only consulted when StorageConfig::max_open_writers_total is None; otherwise all tiers share the global budget. 0 disables the cap (lifts to usize::MAX); None falls back to a tier-appropriate default (STS: 512, MTS/LTS: 64 — STS gets the bulk because it’s the live ingest path).
