Hi, This question duplicates with a post in 2019 What are the best migration tools for Cassandra? and the answer was "there isn't such a tool in Cassandra". Hope the tooling landscape has improved since then.
The typical usage of this tool is to apply incremental changes to schema during the entire life cycle of an application. Let assume the dev team starts with an initial schema. Works Ok until a business logic change which requires to add a new column C1 in table T1. Then 2 weeks later, column Cn in table Tn needs to change data type from string to integer, etc.
A schema maintenance/versioning tool, like Flyway for relational DB, allows to write scripts which are sourced controled. Then apply the incremental changes in chronological order in an idempotent fashion. ie. a change which is already applied will be skipped.
QUESTION: Can you please recommend such a tool for Cassandra?
