[GitHub] [iceberg] steveloughran opened a new issue #2124: Improve HadoopCatalog performance/scalability

steveloughran opened a new issue #2124:
URL: https://github.com/apache/iceberg/issues/2124


   By moving HadoopCatalog onto `listStatusIterator()` list API calls, filesystem clients which do paged listings (hdfs, webhdfs, s3a, and soon abfs) can mix prefetching of the next page of results while HadoopCatalog examines the current entries. This makes a difference on object stores. (Not that you should be using HadoopCatalog on S3; ABFS is a different matter)

   Thanks for submitting a fix for this, @steveloughran. Seems like this issue is resolved but I am wondering whether we should add this functionality to other places like `RemoveOrphanFilesAction` that do lists as well.
