Precautions

  • Only instants that are not cleaned can be archived.
  • No matter whether the compaction operation is performed, at least x (x indicates the value of hoodie.compact.inline.max.delta.commits) instants are retained and not archived to ensure that there are enough instants to trigger the compaction schedule.

System Response

You can view command execution results in the driver log or on the client.
