steFaiz opened a new pull request, #7921: URL: https://github.com/apache/paimon/pull/7921
### Purpose This is the part0 of https://github.com/apache/paimon/issues/7881 Currently, we can't add new blob columns through Flink/Spark sql. In this PR, I slightly changes the restriction of altering `blob-fields` configuration, as below: 1. Do not allow altering an existing fields to BLOB 2. Do not allow removing an existing fields from blob fields 3. Allow configuring a non-existing fields as blob -- this is for future blob fields Then during altering tables, new bytes fields with blob-fields configured will be converted to blob fields, as below: ```sql -- current setting is only 'blob-field'='video' ALTER TABLE T_BLOB SET ('blob-field'='video,picture'); ALTER TABLE T_BLOB ADD picture BYTES ``` ### Tests See Unit Tests and ITCases -- This is an automated message from the Apache Git Service.
