Review Comment:
The `--limit` is used to limit the total count of records, the
`--max-records-per-file` is used to limit the max records count of specific
file.
Such as:
` ozone debug ldb ... --limit 10 --max-records-per-file 1 --out result.txt`
This command should generate 10 files, like result.txt0, result.txt1, ...,
and each of them has 1 record.
