Narrow scope needs custom logic
“They've made some unique choices that work great for them, but it really doesn't seem like they can be universally applied.”
Comment from 28 Oct 2026 in “Four Months of Zig” “it handles so little you will have to roll a lot of custom logic around it to batch realtime transactions quickly”
Comment from 11 Nov 2025 in “Building a high-performance ticketing system with TigerBeetle” Seen as simple key-value store
“tiger beetle is awesome to keep the account balance. that's it.”
Comment from 16 Apr 2026 in “TigerBeetle: A Trillion Transactions [video]” “This looks like yet another basic key value store.”
Comment from 16 Apr 2026 in “TigerBeetle: A Trillion Transactions [video]” Non-batch performance drop disappointed
“Was there something wrong with our test of the individual transactions in our Go script that caused the drop in transaction performance we observed?”
