[jira] [Commented] (ARROW-12524) [Parquet][C++] Support arrow dense union type in Parquet

    [ https://issues.apache.org/jira/browse/ARROW-12524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17337758#comment-17337758 ] 

ZMZ91 commented on ARROW-12524:
-------------------------------

Thanks. I'm moving to support sparse union in parquet. For the value offsets data in sparse union array, do you think it's doable to save it in level info and read it back when building the sparse array data?

> Dense union type is not supported yet in Parquet [https://github.com/apache/arrow/blob/8e43f23dcc6a9e630516228f110c48b64d13cec6/cpp/src/parquet/arrow/schema.cc#L382] . Is it on schedule to support it nearly? If I'd implement this myself, is there any other codes to take care of? Thanks.
