aokolnychyi opened a new pull request #351: Provide an API to modify records within files URL: https://github.com/apache/incubator-iceberg/pull/351 We need an API to remove some existing files and add new ones to perform "eager" updates and deletes. While `RewriteFiles` is doing exactly this, it is designed for cases like compaction, where a set of files is replaced but the content does not change. This PR introduces a way how to perform "eager" updates and deletes. Right now, we do partition-level conflict resolution but it can be enhanced further by leveraging columns stats. The isolation level can be either serializable or snapshot isolation. Original credit goes to @miguelnmiranda.
