kz930 opened a new issue, #8479:
URL: https://github.com/apache/texera/issues/8479

   ### Task Summary
   
   The same gap as #8478, on the other kind of column. Grouping by a continuous 
number puts almost every row in a group of its own, so counts per age bracket 
or per price band cannot be asked for. A user wanting them had to write a 
Python UDF.
   
   An operator that cuts a numeric column into bins closes it. Two cuts, 
because they answer different questions: equal width divides the span into bins 
of one size, and equal frequency cuts at the quantiles so the bins hold about 
as many rows as each other. The bin reads as its own range, `(2.5, 5.0]`, which 
is a label to group by rather than a number to do arithmetic on.
   
   It reads the whole table before it emits, since a quantile is not known 
until the last row has arrived.
   
   Twenty-fourth of the steps listed in #8325. It ships standalone code, so it 
comes after the trait #8327 introduces.
