Struct persist::indexed::encoding::UnsealedBatchMeta

pub struct UnsealedBatchMeta {
    pub key: String,
    pub format: ProtoBatchFormat,
    pub desc: Range<SeqNo>,
    pub ts_upper: u64,
    pub ts_lower: u64,
    pub size_bytes: u64,
}

The metadata necessary to reconstruct a BlobUnsealedBatch.

Invariants:

• The [lower, upper) interval of sequence numbers in desc is non-empty.

Fields

key: String

The key to retrieve the BlobUnsealedBatch from blob storage.

format: ProtoBatchFormat

The format of the stored batch data.

desc: Range<SeqNo>

Half-open interval [lower, upper) of sequence numbers that this batch contains updates for.

ts_upper: u64

The maximum timestamp of any update contained in this batch.

ts_lower: u64

The minimum timestamp from any update contained in this batch.

size_bytes: u64

Size of the encoded batch.
