David Chen updated TAJO-30:
---------------------------
Description:
Parquet is a columnar storage format developed by Twitter. Implement Parquet
(http://parquet.io/) support for Tajo.
The implementation consists of the following:
* {{TajoParquetReader}} and {{TajoParquetWriter}} - Top-level reader and
writer for serializing/deserializing to Tajo Tuples.
* {{TajoReadSupport}} and {{TajoWriteSupport}} - Abstractions to perform
conversion between Parquet and Tajo records.
* {{TajoRecordMaterializer}} - Materializes Tajo Tuples from Parquet's
internal representation.
* {{TajoRecordConverter}} - Used by {{TajoRecordMateriailzer}} to materialize
a Tajo Tuple.
* {{TajoSchemaConverter}} - Converts between Tajo and Parquet schemas.
was:
Parquet is very promising file format developed by twitter. We need to
investigate the applicability of Parquet. If possible, we implement Parquet
port.
