[jira] [Commented] (SPARK-4176) Support decimals with precision >
18 in Parquet
[ https://issues.apache.org/jira/browse/SPARK-4176?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14580206#comment-14580206 ]
Rene Treffer commented on SPARK-4176:
-------------------------------------
Given that SPARK-7897 loads "unsigned bigint" as DecimalType.unlimited means you can now load tables with unsigned bigint but won't be able to store them in parquet files :-(
> Support decimals with precision > 18 in Parquet
> -----------------------------------------------
>
> Key: SPARK-4176
> URL: https://issues.apache.org/jira/browse/SPARK-4176
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 1.3.0, 1.3.1, 1.4.0
> Reporter: Matei Zaharia
> Assignee: Cheng Lian
>
> After https://issues.apache.org/jira/browse/SPARK-3929, only decimals with precisions <= 18 (that can be read into a Long) will be readable from Parquet, so we still need more work to support these larger ones.
