   Sure! I just tried it out, but I'm getting an auth error from the GitHub 
API: "Must specify two-factor authentication OTP code."
   Did I miss some configuration step?

> Currently we repeat dictionary lookups every time we bind a new record batch 
> when doing an equality check in a DataFrame op 
> (https://github.com/apache/arrow/blob/master/js/src/predicate.ts#L143).
> In most cases the dictionary won't be changing between record batches, so we 
> should remember these reverse dictionary lookups, either permanently, or at 
> least for the duration of the current operation.
