I always wanted to ship a write-only database. Lightning fast.

Back in the 80s a professor at our college got a presentation on the concept of «write-only memory» accepted for some symposium.

Good times.

Very secure!

Pretty much how eventstoredb works. Deleting data fully only happens at scavenge which rewrites the data files.

[hxtk]

I think it was a joke. It sounds like you read it as append-only, like most LSM tree databases (not rewriting files in the course of write operations), but I think GP meant it as write-only to the exclusion of reads, roughly equivalent to `echo $data > /dev/null`

That would be useful for logging.

[warkdarrior]

If it's write-only, and no reads ever happen, one can write to /dev/null without loss of utility.

Also useful for backups, so long as you don't need to restore.
