> Add support in CQLSH for COPY FROM / TO in compact Parquet format

>                 Key: CASSANDRA-17831
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17831
>             Project: Cassandra
>          Issue Type: Improvement
>          Components: Tool/cqlsh
>            Reporter: Brad Schoening
>            Priority: Normal
>
> CQL supports only CSV as a format for import and export. A binary big data 
> format such as Avro and/or Parquet would be more compact and highly portable 
> to other platforms.
> Parquet does not require a schema, so it appears the easier format to support.
> The existing syntax supports adding key value pair options, such as FORMAT = 
> PARQUET
> {{     COPY table_name ... FROM 'file_name'[, 'file2_name', ...] }}
>                      {{[WITH option = 'value' [AND ...]]}}
> Side by side comparisons of CSV and Parquet show a 80% plus saving in disk 
> space.
