rdblue opened a new pull request #21: Add manifest listing files URL: https://github.com/apache/incubator-iceberg/pull/21 This adds a separate file, a manifest list, to track the manifests for a snapshot. The manifest list is an Avro file with a row for each manifest. The file columns are used to avoid reading manifests to look for data files. Columns include: * `manifest_path`: path of the manifest file * `partition_spec_id`: ID of the partition spec used to write the manifest (depends on #3) * `added_snapshot_id`: snapshot ID when the manifest was added to the table * `added_data_files_count`, `existing_data_files_count`, `deleted_data_files_count` to track operations * `partitions`: a summary (min, max, and containsNull for each field) of the partitions in the manifest file
