eric-maynard opened a new pull request, #13709: URL: https://github.com/apache/iceberg/pull/13709
This adds support for the DELTA_LENGTH_BYTE_ARRAY [Parquet encoding](https://parquet.apache.org/docs/file-format/data-pages/encodings/). The logic is taken from Spark's [VectorizedDeltaLengthByteArrayReader](https://github.com/apache/spark/blob/8fac87e8cbe952c4965bbcaf363bf0af10c4dc18/sql/core/src/main/java/org/apache/spark/sql/execution/datasources/parquet/VectorizedDeltaLengthByteArrayReader.java#L33) with adjustments made for compatibility with our existing Parquet reader. Because this encoding is not used by default for any types in the Parquet writer, it's challenging to test this with files generated at test time. For that reason, this PR remains a draft while #13450 is in review. -- This is an automated message from the Apache Git Service.
