ConeyLiu opened a new pull request, #4842:
URL: https://github.com/apache/iceberg/pull/4842

   This patch adds the support of file filtering based on the schema. This aims 
to reduce the file scan time when we have done a schema evaluation. For the 
following example:
   ```
   1. create a table with schema <id: long, name: string> and partition on id
   2. add new files
   3. update the schema and add a new column: address. Now the schema is <id: 
long, name: string, address: string>
   4. add new files
   // Before this patch, we have to read those files added at 2 and do the 
filter after reading those files.
   6. scan with filter start_with('address', 'some_value') and id > 10;
   ```
