andygrove opened a new issue #834:
URL: https://github.com/apache/arrow-datafusion/issues/834
**Describe the bug**
We use Int32 to represent keys and at SF=1000 we generate values >
2,147,483,647, resulting in errors like this:
```
Error: ArrowError(ExternalError(ArrowError(ExternalError(Execution("Arrow
error: External error: Execution error: Arrow error: External error: Execution
error: Arrow error: Parser error: Error while parsing value 3000000002 for
column 0 at line 1")))))
```
**To Reproduce**
Generate SF=1000 data set and try running queries.
**Expected behavior**
We should use a more appropriate data type for keys. Perhaps UInt64.
**Additional context**
None
