**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** While evaluating queries against data stored in containers / multiple files, it is helpful to prune entire files using statistics (see #363 for more details). DataFusion has this logic already for `==`, `<`, `<=`, `>` and `>=` operators in the pruning predicate. However, as @NGA-TRAN noticed, there is no support for `!=` at the moment. https://github.com/apache/arrow-datafusion/blob/14f1eebef068a9e65f556ed74d2b6d98376c97f4/datafusion/src/physical_plan/parquet.rs#L683 **Describe the solution you'd like** Add support and tests for `!=` in predicate pruning logic -- This is an automated message from the Apache Git Service.
