"@AlexMillerDB @dxhuang also the screenshotted text is a quote reply to another message about DSQL using Rust. So Moritz was replying in that context of why not Rust for Cedar DB"

"Loved reading this excellent post by @MarcJBrooker and @ankushpd: Systems Correctness Practices at Amazon Web Services on how they use formal methods internally at AWS. One of the best articles I've read this year on formal verification and testing. I liked how this article lists various methods and how they're used to solve particular cases. Also includes references to some great papers"

"AWS published a blog post: An Aurora DSQL Story. It's less about database development and more like a love letter to Rust. DSQL's initial development was in Kotlin but they weren't happy with its performance. So two engineers who had never written Rust before rewrote a component in Rust. The code was 10x faster even though they didn't make any attempt to optimize it. They had spent years carefully tuning the Kotlin version which did 3000 TPS. The Rust one clocked 30000 TPS. Insane They wanted to extend Postgres. Instead of C they chose Rust again for memory safety reasons. For tooling reasons"

"There is a new fork of RocksDB called ToplingDB which claims to be 8x faster In the Memtable SkipList is replaced by CSPP (Crash Safe Parallel Patricia trie). In SST BlockBasedTable is replaced by ToplingZipTable which seems to be their internal table with built in compression. They have already integrated with MySQL in MyTopling a fork of MyRocks"
