Yeah, and I also added support for parallel read your own writes where you can write tons of entries and spawn multi children read-only transactions from your writes where transaction and read from them in parallel.

We use this in Meilisearch [1] to post-process cache for our most common prefixes i.e., "w" will match "work", "word"... and computing this requires doing large unions of the documents matching those words.

Being able to do it in parallel is necessary, especially when you have billions of entries to operate on.
