Rahil Chertara commented on HUDI-5608:
--------------------------------------
Synced with Alexey, based on our dicussion we will need to add an additional
DecimalWrapperV2 to the schema, and make this flexible to encode the precision
and scale.
> Support decimals w/ precision > 30 in Column Stats

> Key: HUDI-5608
> URL: https://issues.apache.org/jira/browse/HUDI-5608
> Project: Apache Hudi
> Issue Type: Bug
> Components: spark
> Affects Versions: 0.12.2
> Reporter: Alexey Kudinkin
> Priority: Critical
>
> As reported in: [https://github.com/apache/hudi/issues/7732]
>
> Currently we've limited precision of the supported decimals at 30 assuming
> that this number is reasonably high to cover 99% of use-cases, but it seems
> like there's still a demand for even larger Decimals.
> The challenge is however to balance the need to support longer Decimals vs
> storage space we have to provision for each one of them.
