No long-term profiles visible: invalid magic footer of parquet file

Thanks for the report. I'm uncertain what would cause this but I'm curious if you're able to recreate this using the latest version 0.20.0 there were significant updates to the database.

If you inspect the storage do you notice a lot of corrupt files or is it just one?

I will try to test with 0.20.0 and let you know.

Regarding corrupt files. I suspect data.parquet file is corrupted, but did not find any tool how to check if it is true. Also, there are plenty of stacktrace blocks on storage, is there any way to know which is causing problem?

You should be able to use any off the shelf parquet tool like parquet-tools or parquet-cli to inspect the files to determine which one(s) are corrupt.
