[jira] [Commented] (ARROW-10118) [Rust] [DataFusion] Add support
for JSON data sources
[ https://issues.apache.org/jira/browse/ARROW-10118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17239845#comment-17239845 ]
Neville Dipale commented on ARROW-10118:
----------------------------------------
[~andygrove] why is it not practical to parse the JSON files first to get the schema?
> [Rust] [DataFusion] Add support for JSON data sources

> Key: ARROW-10118
> URL: https://issues.apache.org/jira/browse/ARROW-10118
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Rust, Rust - DataFusion
> Reporter: Andy Grove
> Priority: Major
>
> Arrow already has a JSON reader and it would be nice to integrate this with DataFusion so that queries can be run against JSON files.
> This would probably not be trivial though since we would need to add support for schemaless data sources (it isn't practical to parse the JSON files first to extract the schema).
