Topic: Can you Update a Primary Key in Scylla?
Audience: Scylla administrators
In Scylla, you cannot update a primary key. It is impossible to do so.
However, you can migrate the data from the old table with the old primary key to a new table with a new primary key. There are two ways to handle the migration:
Fork-lifting the historical data with the Spark Migrator tool.
Double writing the new data.
