@@ -84,6 +84,7 @@ The following configuration settings are available:
8484
| datafusion.execution.parquet.metadata_size_hint | 524288 | (reading) If specified, the parquet reader will try and fetch the last `size_hint` bytes of the parquet file optimistically. If not specified, two reads are required: One read to fetch the 8-byte parquet footer and another to fetch the metadata length encoded in the footer Default setting to 512 KiB, which should be sufficient for most parquet files, it can reduce one I/O operation per parquet file. If the metadata is larger than the hint, two reads will still be performed. |
8585
| datafusion.execution.parquet.pushdown_filters | false | (reading) If true, filter expressions are be applied during the parquet decoding operation to reduce the number of rows decoded. This optimization is sometimes called "late materialization". |
8686
| datafusion.execution.parquet.reorder_filters | false | (reading) If true, filter expressions evaluated during the parquet decoding operation will be reordered heuristically to minimize the cost of evaluation. If false, the filters are applied in the same order as written in the query |
87+
| datafusion.execution.parquet.force_filter_selections | false | (reading) Force the use of RowSelections for filter results, when pushdown_filters is enabled. If false, the reader will automatically choose between a RowSelection and a Bitmap based on the number and pattern of selected rows. |
8788
| datafusion.execution.parquet.schema_force_view_types | true | (reading) If true, parquet reader will read columns of `Utf8/Utf8Large` with `Utf8View`, and `Binary/BinaryLarge` with `BinaryView`. |
8889
| datafusion.execution.parquet.binary_as_string | false | (reading) If true, parquet reader will read columns of `Binary/LargeBinary` with `Utf8`, and `BinaryView` with `Utf8View`. Parquet files generated by some legacy writers do not correctly set the UTF8 flag for strings, causing string columns to be loaded as BLOB instead. |
8990
| datafusion.execution.parquet.coerce_int96 | NULL | (reading) If true, parquet reader will read columns of physical type int96 as originating from a different resolution than nanosecond. This is useful for reading data from systems like Spark which stores microsecond resolution timestamps in an int96 allowing it to write values with a larger date range than 64-bit timestamps with nanosecond resolution. |
