rdblue opened a new pull request #4154: URL: https://github.com/apache/iceberg/pull/4154
Some Spark tables support an option, `mergeSchema`, that will update the table schema on write if the incoming data has extra columns. This shows how Iceberg could support the `mergeSchema` option. Right now, this would not fully work because `SparkTable` would need to return `TableCapability.ACCEPT_ANY_SCHEMA` to disable Spark schema validation and rely completely on Iceberg. We would probably want to add a `SparkConf` setting to enable this. -- This is an automated message from the Apache Git Service.
