Most tools I tried either:
Assume simple linear migrations
Don’t work well with managed Cassandra setups
Or make it hard to understand the actual state of a cluster
So I built cassachange.
It supports:
Apache Cassandra Managed Cassandra AstraDB (including SCB) ScyllaDB
It handles schema migrations, but I also added data insights and MCP capabilities because understanding the current cluster state is often half the battle.
A few things I’m especially curious about:
How are people managing Cassandra schema changes in production today?
Are most teams still using raw CQL scripts?
How do you handle drift between environments?
Has anyone built internal tooling for this?
I’d love critical feedback — especially from people running Cassandra/Scylla at scale.
