aokolnychyi opened a new issue #397: Push down StringStartsWith in Spark IcebergSource URL: https://github.com/apache/incubator-iceberg/issues/397 Apart from changes in `SparkFilters`, we will need to extend `InclusiveMetricsEvaluator`, `ParquetDictionaryRowGroupFilter`, `ParquetMetricsRowGroupFilter` with the logic that checks lower/upper bounds in `startsWith`. One way to implement this is to take the same number of bytes from prefix and bounds (e.g. slice) and then rely on `UnsignedByteBufComparator` for unsigned lexicographical comparison.
