Interesting. Can you elaborate more? What extra info does it provide additional to the spans we attached in MonitoredObjectStore?

Recently we are debugging #15209, and found that the await tree of compactor node is a bit less:

--- Compactor Traces ---
>> Compaction Task 50708-0
Compaction Task 50708 Split 0  [1843.496s]
  compact [!!! 1843.496s]
    compact_and_build_sst [!!! 1843.496s]
      rewind [!!! 1843.496s]
        object_store_streaming_read_read_bytes [!!! 1843.456s]

>> Compaction Task 51832-0
Compaction Task 51832 Split 0  [1062.498s]
  compact [!!! 1062.498s]
    compact_and_build_sst [!!! 1062.498s]
      add_full_key [!!! 1061.768s]
        object_store_streaming_upload_write_bytes [!!! 1061.768s]

and OpenDAL provide AwaitTreeLayer, which will show the interfaces in it's operator level. With this await tree layer enabled, we will get these info right behind RisingWave's own trace file.

The bug is fixed, but it's still worth adding it and not complicated.

Can you give an example file of OpenDAL's await tree, collected from RisingWave?

LGTM. Do you think it needs to run a benchmark before merging?

+1， testing to get await-tree file before merge
