------------------------------------
Summary: [JS] Lazy row accessor in Table
Key: ARROW-1651
URL: https://issues.apache.org/jira/browse/ARROW-1651
Project: Apache Arrow
Issue Type: Improvement
Components: JavaScript
Reporter: Brian Hulette
Priority: Minor
Right now the {{Table}} class has a {{*rows}} function for grabbing a series of
rows, but the only available formats for the returned data are an Array and an
Object for each row, which contain the value from every column.
It would be useful to have the option to yield some kind of lazy accessor for
each row, so that end users can only access the columns they are actually
using. This would have caching benefits, and save us from doing dictionary
lookups and/or string decodes on unused columns.
I'm not sure exactly what form this accessor would take. Perhaps a function
that accepts a column name/index? Or an array with a function for each column?
Or maybe there's some other new JS pattern that could accomplish this.
