--------------------------------------
Thanks.
(Could you create a new Jira issue for the segmentation fault with an invalid precision?)
[~mrkn] What do you think about this?

> Key: ARROW-14518
> URL: https://issues.apache.org/jira/browse/ARROW-14518
> Project: Apache Arrow
> Issue Type: Bug
> Components: Ruby
> Reporter: Kanstantsin Ilchanka
> Priority: Minor
>
> When trying to convert raw data with decimal values to Arrow::Table error received
>
> {code:java}
> Arrow::Table.new(x: [BigDecimal('1.1')])
> ArgumentError: wrong arguments: Arrow::Decimal128ArrayBuilder#initialize(): available signatures: (data_type: interface(Arrow::Decimal128DataType(GArrowDecimal128DataType)))
> {code}
> I guess this is because Decimal128ArrayBuilder expects Decimal128DataType in initialiser, however I'm not sure how to correctly and effectively detect precision and scale from array of BigDecimal
>
> {code:java}
> Arrow::VERSION
> => "5.0.0"{code}
