Jing Ge commented on FLINK-32906:
---------------------------------
The idea behind it is to enable users to show content of table in a feasible
way. Afiak, it is expected to truncate char. [~jark] would you please double
confirm? Thanks!

> SqlClient and Table APi in both Streaming and Batch execMode

> Tests:
> Both configs could be set with new value and following behaviours are
> expected :
> | | |sql-client.display.max-column-width, default value is
> 30|table.display.max-column-width, default value is 30|
> |sqlclient|Streaming|text longer than the value will be truncated and
> replaced with “...”|Text longer than the value will be truncated and replaced
> with “...”|
> |sqlclient|Batch|text longer than the value will be truncated and replaced
> with “...”|Text longer than the value will be truncated and replaced with
> “...”|
> |Table API|Streaming|No effect.
> table.display.max-column-width with the default value 30 will be used|Text
> longer than the value will be truncated and replaced with “...”|
> |Table API|Batch|No effect.
> table.display.max-column-width with the default value 30 will be used|Text
> longer than the value will be truncated and replaced with “...”|
>
> Please pay attention that this task offers a backward compatible solution and
> deprecated sql-client.display.max-column-width, which means once
> sql-client.display.max-column-width is used, it falls into the old scenario
> where table.display.max-column-width didn't exist, any changes of
> table.display.max-column-width won't take effect. You should test it either
> by only using table.display.max-column-width or by using
> sql-client.display.max-column-width, but not both of them back and forth.
