Hi, I have a question > Do Spark Iceberg Implement Copy On Write Delete and Update? * I find [this MR](https://github.com/apache/iceberg/pull/351), so Iceberg itself supports it. But what about implementation in spark? Looking on [this code](https://github.com/apache/iceberg/blob/master/spark3/src/main/java/org/apache/iceberg/spark/source/SparkWriteBuilder.java#L87) I can say that at least Spark 3 supports it, am I right? * But looking to spark the only usage of this builder method is in delete sections of org.apache.spark.sql.execution.datasources.v2.OverwriteByExpressionExecV1 and OverwriteByExpression. * So does it possible to implement Eager(CopyOnWriteUpdate) or there is some known issues?
