Each mark is one comment
Strong performance and low latency
“since it is written in cpp and doesnt have the performance bottlenecks jvm brings”
Comment from 7 Feb 2026 in “So you care about tail latency?” “scylla utilizes this fact with cpu pinning across cpus and other tricks”
Comment from 3 Feb 2026 in “So you care about tail latency?” Specialized for specific use cases
“There's still lots of room for specialization tuned database options like Cassandra, Scylla, etc.”
Comment from 27 Apr 2026 in “Branimir Lambov from IBM on Cassandra” “excellent db's meant for very specific use cases”
Comment from 27 Apr 2026 in “Branimir Lambov from IBM on Cassandra” Used for key-value and high-scale workloads
“Won't something like scyllaDB be a better choice for such workloads ?”
Comment from 28 Jan 2026 in “Show HN: Actionbase – A database for likes, views, follows at 1M+ req/min” “They use redis, dynamo, scylla or any number of enriched KV stores.”

What people warn about
Each mark is one comment
Open-source version discontinued
“since they discontinued their Open Source version we're stuck on the last supported version”
Comment from 21 Aug 2026 in “The road to ACID transactions in Cassandra 6” “Issue is that it’s no longer open source”
Comment from 21 Aug 2026 in “The road to ACID transactions in Cassandra 6” Paid support needed; open core
“The oss is lagging and you ultimately need to end up paying the company for support.”
Comment from 24 Aug 2026 in “The road to ACID transactions in Cassandra 6” “far more insidious "open core only"”
Comment from 8 Jan 2026 in “Creators of Tailwind laid off 75% of their engineering team” Costly to maintain and migrate
“aren't they struggling for the same reasons: not the default, faster horse, costly to maintain”
Comment from 23 Jan 2026 in “Turso is an in-process SQL database, compatible with SQLite” “There is no reasonable way of replacing a huge existing cassandra cluster with scylladb.”
