bknbkn opened a new pull request, #11387: URL: https://github.com/apache/iceberg/pull/11387
fix #11314 In the previous code, each spec reads the latest schema. After deleting the corresponding field, the historical spec cannot find the corresponding field in the current schema, and an error will occur. This patch **persist the schema id corresponding to the spec. The historical spec can read the corresponding schema, and the current spec will be updated to the current schema** But even if the partition field is deleted in the V1 table, it will not be deleted in the spec. Therefore, the latest spec is not compatible with the schema after the field is deleted. So I prefer to forbid the V1 table from deleting the existing partition field (by Partition#checkCompatibility method guarantee) For V2 tables, it is safe to delete the corresponding column after deleting the partition field -- This is an automated message from the Apache Git Service.
