[jira] [Commented] (PARQUET-129) AvroParquetWriter can't save object who can have link to object of same type

["Ryan Blue (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PARQUET-129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14205005#comment-14205005 ] 

Ryan Blue commented on PARQUET-129:
-----------------------------------

I think the correct resolution is to catch recursive schemas and fail. We could design a system for storing recursive records, but it would be a lot of work. So if we need this feature in the long term we can keep this open, but the short-term solution is to reject schemas like this.
