- Dremel Assembly

- Online demo of dremel assembly of lists from definition and repetition levels.
-
-
- Google introduced dremel in 2010 as a columnar storage format for nested data.
- The format uses repetition levels and definition levels to encode nested data efficiently.
- This demo maps definition and repetition levels to assembled lists.
-
-
- This demo is developed as a learning and debugging tool as part of hyparquet : a parser for apache parquet files.
