Dominik Moritz resolved ARROW-9496.
-----------------------------------
Resolution: Won't Fix
Not a problem anymore since Arrow does not have a filtered data frame anymore.
> [JS] toArray() called on filtered Table returns all rows
> --------------------------------------------------------
>
> Key: ARROW-9496
> URL: https://issues.apache.org/jira/browse/ARROW-9496
> Project: Apache Arrow
> Issue Type: Bug
> Components: JavaScript
> Environment: OSX 10.15.2
> Behavior seen in browser and node
> Reporter: Peter Murphy
> Priority: Major
>
> Trying to experiment with building a library on top of Apache Arrow's
> Javascript implementation, but ran into this:
> Example:
> [https://runkit.com/pjm17971/pond-arrow]
> {code:java}
> const filtered = table.filter(predicate.col("pressure").lt(28.5))
> filtered.count() // 2 (correct)
> {code}
> However:
> {code:java}
> const result = filtered.toArray().map(row => row.toJSON()) // 4 rows
> (??){code}
> Is this expected behavior?
