> CLI: Truncate table columns to fit terminal width
> -------------------------------------------------
>
> Key: IGNITE-27515
> URL: https://issues.apache.org/jira/browse/IGNITE-27515
> Project: Ignite
> Issue Type: Improvement
> Reporter: Aleksandr
> Assignee: Aleksandr
> Priority: Major
> Labels: ignite-3
> Time Spent: 2.5h
> Remaining Estimate: 0h
>
> Implement column truncation in SQL REPL to prevent tables from exceeding
> terminal width.
> _Problem:_
> Wide tables with many columns or long cell values break terminal formatting.
> Horizontal scrolling is not available, and tables become unreadable.
> _Solution:_
> Detect terminal width using JLine's terminal.getWidth() and
> truncate/distribute column widths to fit.
> _New config keys:_
> * ignite.cli.output.truncate (boolean, default: true)
> * ignite.cli.output.max-column-width (integer, default: 50)
> _Command-line flags:_
> * --max-col-width N - override default max column width
> * --no-truncate - disable truncation (show full content)
> _Considerations:_
> * Priority columns (e.g., primary key, ID) may need more width
> * Numeric columns should not be truncated mid-number
> * Consider smart truncation for different data types
