Used in: VectorLSMChunkPB

• optional google.protobuf.Any user_frontier = 1

Information about added chunk.

Used in: VectorLSMUpdatePB

• uint64 serial_no = 1

  Serial no is unique for all chunks created during vector lsm lifetime. Used in chunk filename and never changes.

• uint64 order_no = 2

  Position in the in-memory chunk list. Not required to be unique. Used on the write path to manifest chunks in the correct order. On flush, set to max(existing order_no) + 1. On compaction, each output chunk gets the order_no of the latest input chunk that contributed vectors to it.

• optional VectorLSMBoundaryPB smallest = 4

• optional VectorLSMBoundaryPB largest = 5

• bytes vertex_id = 1

  16 bytes uuid

• bool reset = 1

  When reset is true, all previous updates should be ignored.

• repeated VectorLSMChunkPB add_chunks = 2

  Chunks could be added and removed within the single update. But the same chunk cannot be added and removed within the single update.

• repeated uint64 remove_chunks = 3
