[jira] [Commented] (ARROW-2786) [JS] Read Parquet files in JavaScript

["Paul Taylor (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-2786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16922744#comment-16922744 ] 

Paul Taylor commented on ARROW-2786:
------------------------------------

There are a few JS Parquet implementations, with [parquetjs|https://www.npmjs.com/package/parquetjs] being the more mature one from what I recall.

A while back I put together [this demo|https://github.com/trxcllnt/arrow-to-parquet-js] converting Arrow -> Parquet in pure JS. The major drawback is the ParquetJS writer is row-oriented, so performance will be an issue.

I opened [this issue|https://github.com/ironSource/parquetjs/issues/84] to get some clarification, but haven't heard back yet.
