--------------------------------------------
Summary: [Ruby] ArrayBuilder doesn't work correctly with Decimal
Key: ARROW-14518
URL: https://issues.apache.org/jira/browse/ARROW-14518
Project: Apache Arrow
Issue Type: Bug
Components: Ruby
Reporter: Kanstantsin Ilchanka
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}
