asubiotto opened a new issue, #38918: URL: https://github.com/apache/arrow/issues/38918
### Describe the enhancement requested https://github.com/apache/arrow/pull/35307 changed schema.Fields to return a copy of the fields for safety: https://github.com/apache/arrow/blob/c614014db805caf3bbc4d5270bd990c095bf8725/go/arrow/schema.go#L198 However, a big part of the codebase continues to use schema.Fields assuming it is zero-allocation. We should review all callsites and change to using `NumFields` in cases where we only need the number of fields and looping over the field indices rather than the result of `schema.Fields`. ### Component(s) Go -- This is an automated message from the Apache Git Service.
