Prepares the SST file for ingestion. The purpose is to make the ingestion retryable when using the move_files option. Things we need to consider here:

  1. We need to access the original file on retry, so we should make a clone before ingestion.
  2. RocksDB will modified the global seqno of the ingested file, so we need to modified the global seqno back to 0 so that we can pass the checksum validation.
  3. If the file has been ingested to RocksDB, we should not modified the global seqno directly, because that may corrupt RocksDB’s data.
