Description

I noticed that the JsonDebeziumSchemaSerializer only detects schema changes with ADD or DROP. May I ask whether the reason why 'alter table change column' statements are not synchronized is due to lack of support or for some other reason?

doris light schema change only supports add and drop columns. Other ddl operations will modify historical data, so it is relatively slow. You can refer to https://mp.weixin.qq.com/s/UqQnTJkGZhmMYxnUO9rdaQ
