Expected behaviour when dropping columns?

[aurany]

Adding columns seems to work fine using evolve-schema-enabled: true but dropping columns does not affect the resulting iceberg table. Is this expected?

I'm using cassandra and debezium with cdc enabled.

The connector won't delete columns. The most it will do is make one optional.

I was incorrect. There is a bug --the connector can throw when columns are deleting. We are in the process of fixing this. Will link the PR when it is available.
