Struct ShardedSparseConfig 

pub struct ShardedSparseConfig {
    pub version: u32,
    pub shards: usize,
    pub balance_weight: f64,
    pub df_threshold: u32,
}

Persisted as _sparse_config.json at the root of the storage.

Versioned and tolerant on purpose: it used to carry deny_unknown_fields and no version, so the day a field was added, the previous release could no longer read the file — the compatibility was structurally broken for this one file, while the shard router next to it does it right (magic SHRD, version, a range of readable versions). A field this build does not know is now ignored, and version says what wrote the file.

Fields

version: u32

Format of this file. Absent means the versionless original (0).

shards: usize

Number of shards, at least 1.

balance_weight: f64

Routing balance, 0.0..=1.0: 1.0 is round-robin (the default), lower values co-locate vectors sharing dimensions on the same shard.

df_threshold: u32

Dimensions with a global document frequency above this are not tracked for routing (they carry no locality information).
