I observed a significant performance improvement just testing on the master branch without any metadata caching as compared to before. ``` ➜ datafusion git:(main) ✗ ./target/debug/datafusion-cli DataFusion CLI v48.0.0 > CREATE EXTERNAL TABLE nyc_taxi_rides STORED AS PARQUET LOCATION 's3://altinity-clickhouse-data/nyc_taxi_rides/data/tripdata_parquet/'; 0 row(s) fetched.
