[jira] [Comment Edited] (ARROW-7085) [C++][CSV] Add support for
Extention type in csv reader
[ https://issues.apache.org/jira/browse/ARROW-7085?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16970050#comment-16970050 ]

-----------------------------------------------------------------
[~wesm], [~apitrou] For our purposes we need to define a custom type and use arrow CSV reader to parse it. Unfortunately, there is no way to use custom types with CSV reader right now, because of type dispatch when choosing an appropriate column builder.
I'm not sure how architecturally it could be solved, maybe custom ColumnBuilder is a case.
