eric-maynard opened a new pull request, #1456:
URL: https://github.com/apache/polaris/pull/1456

   For rest catalogs, `TableOperations.refresh()` can result in an expensive 
trip to object storage. Despite this, the method is called quite frequently and 
is currently called after every commit when we construct a BaseTable to return 
back to a client that requested a commit.
   
   In some cases, the same TableOperations is used for one commit and then is 
immediately used for another. We can see this in some tests, such as Iceberg's 
`CatalogTests.testUpdateTableSchemaThenRevert`:
   
   ```
   table.updateSchema().addColumn("col1", StringType.get()).addColumn("col2", 
StringType.get()).addColumn("col3", StringType.get()).commit();
   
table.updateSchema().deleteColumn("col1").deleteColumn("col2").deleteColumn("col3").commit();
      
   ```
   
   This PR proposes that the TableOperations can update its `currentMetadata` 
metadata on commit so that future calls to `doRefresh` might be able to skip a 
trip to object storage.

   This is an alternate implementation to #1378 that does not rely on reflection
