------------------------------------------
Assignee: Arvind Kandpal
> Enhance CQLSH to support machine-readable output formatting
> -----------------------------------------------------------
>
> Key: CASSANDRA-19985
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19985
> Project: Apache Cassandra
> Issue Type: New Feature
> Components: CQL/Interpreter
> Reporter: Brad Schoening
> Assignee: Arvind Kandpal
> Priority: Normal
>
> Existing CQLSH output formatting provides tabular formatting using grid-like
> separators and text alignment which is designed for user readability.
> When CQL is run for non-interactive tasks as part of a pipeline this
> formatting complicates the machine processing of the output. As an example,
> [Sqlite|https://www.sqlite.org/cli.html] has a command line flag -mode to
> switch between tablular, csv, and several other supported formats.
> This enhancement will provide a new mode argument which will initially offer
> tabular and csv output formats. Tabular will remain the default so there will
> be no change for existing users. In the future, other modes such as json and
> insert could be added.
> {noformat}
> --mode={tabular, csv}
> Specify an output display format. The default is tabular.
> {noformat}
> The existing Copy To can be used for exporting to CSV, but it doesn't allow
> for query criteria and thus isn't a general solution for this issue.
> In cqlshmain.py, the EXPAND CQLSH option which uses print_formatted_result()
> for result output is an example of alternative formatting.
