}
Expand description

The metadata necessary to reconstruct a list of BlobTraceBatchParts.

Invariants:

  • The Description’s time interval is non-empty.
  • Keys for all trace batch parts are unique.
  • Keys for all trace batch parts are stored in index order.
  • The data in all of the trace batch parts is sorted and consolidated.
  • All of the trace batch parts have the same desc as the metadata.

Fields§

§keys: Vec<String>

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

The set of keys can be empty to denote an empty batch.

§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.
