Struct ChunkMeta

struct ChunkMeta {
    filename: String,
    min_timestamp: i64,
    max_timestamp: i64,
    point_count: u32,
}

Per-chunk metadata for zone map pruning (RFC-002-08).

Stores min/max timestamps so range queries can skip non-overlapping chunks without deserializing their contents. See Lamb et al. (VLDB 2012).

Fields

filename: String

min_timestamp: i64

max_timestamp: i64

point_count: u32
