support:
1. **Predicate pushdown**: Pushdown of the Hive SQL `WHERE` clause has been
implemented so that these filters are used at the Iceberg `TableScan` level as
well as by the Parquet and ORC Readers.
2. **Column projection**: Columns from the Hive SQL `SELECT` clause are
projected down to the Iceberg readers to reduce the number of columns read.
3. **Hive query engines**:
- - With Hive 2.3.x, 3.1.x both the MapReduce and Tez query execution engines
are supported.
- - With Hive 4.0.0-alpha-1 Tez query execution engine is supported.

Some of the advanced / little used optimizations are not yet implemented for
Iceberg tables, so you should check your individual queries.
Also currently the statistics stored in the MetaStore are used for query
planning. This is something we are planning to improve in the future.
