[GitHub] [incubator-paimon] wg1026688210 opened a new issue, #1322: [Feature] Support Column Default Value

wg1026688210 opened a new issue, #1322:
URL: https://github.com/apache/incubator-paimon/issues/1322

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.
   
   
   ### Motivation
   
   In some partial update scenarios, users expect table column defaults to not be null. For example, a table with three fields: is_click, is_sight, is_comment. Two data entries are received: 1,null,null and null,null,1. The expected result is 1,0,1.
   
   ### Solution
   
   we can add default value `xxx` at schema, and convert null to `xxx` when reading , As mentioned above, the final data  1,null,1 will be converted to 1,0,1.
   
   ### Anything else?
   
   I'm willing to submit a PR
