alamb opened a new issue #560: URL: https://github.com/apache/arrow-datafusion/issues/560
**Describe the bug** The logic for pruning on `!=` predicates introduced in https://github.com/apache/arrow-datafusion/pull/544 is incorrect **To Reproduce** Use the pruning logic with a `!=` predicate where the range covers the expression So like `s != M` where the min/max is `A` -> `Z`. **Expected behavior** Must check all values in block (as s!=M might be true for every one) Actual behavior: Pruning logic says we must look at it. **Additional context** I found this issue when integrating / testing DataFusion into IOx here: https://github.com/influxdata/influxdb_iox/pull/1721#issuecomment-860858033 -- This is an automated message from the Apache Git Service.
