[I] panic: array_repeat scalar path overflows total repeated-value count [datafusion]

2026-05-15 Thread via GitHub 


Dandandan opened a new issue, #22218:
URL: https://github.com/apache/datafusion/issues/22218

   ### Describe the bug
   
   `array_repeat` can panic on scalar elements when the total repeated-value 
count overflows `usize` while summing counts.
   
   ### To Reproduce
   
   ```sql
   SELECT array_repeat(1, c)
   FROM (
 VALUES
   (9223372036854775807),
   (9223372036854775807),
   (9223372036854775807)
   ) AS t(c);
   ```
   
   ### Actual behavior
   
   ```text
   thread 'main' panicked at .../library/core/src/iter/traits/accum.rs:204:1:
   attempt to add with overflow
   ```
   
   ### Expected behavior
   
   Return an execution error for an output-size overflow, not a panic.
   
   ### Notes
   
   The overflow comes from summing the per-row repeat counts before building 
the result.
