Struct persist::indexed::encoding::TraceBatchMeta

pub struct TraceBatchMeta {
    pub key: String,
    pub format: ProtoBatchFormat,
    pub desc: Description<u64>,
    pub level: u64,
    pub size_bytes: u64,
}

The metadata necessary to reconstruct a BlobTraceBatch.

Invariants:

• The Description’s time interval is non-empty.
• TODO: key invariants?

Fields

key: String

The key to retrieve the batch’s data from the blob store.

format: ProtoBatchFormat

The format of the stored batch data.

desc: Description<u64>

The half-open time interval [lower, upper) this batch contains data for.

level: u64

The compaction level of each batch.

size_bytes: u64

Size of the encoded batch.
