introduce optional rle reads from parquet by Rich-T-kid · Pull Request #24227 · apache/datafusion

Rich-T-kid · 2026-08-10T15:21:19Z

a large portion of this PR is test!

Which issue does this PR close?

Rationale for this change

When DataFusion reads a parquet file with dictionary-encoded string or binary columns, it currently decodes the dictionary and returns plain Utf8/Binary arrays, discarding the encoding. For low-cardinality columns (status, country, category, etc.) this doesn't take full advantage of the compacted format parquet gives the engine Preserving the dictionary encoding reduces memory usage and can improve aggregation performance on these columns.

What changes are included in this PR?

Adds datafusion.execution.parquet.enable_rle_to_dictionary with a default of false.

When enabled for inferred-schema Parquet tables, DataFusion inspects Parquet footer metadata and promotes top-level string/binary columns with dictionary pages to Arrow dictionary types. Mixed dictionary/plain files are normalized before schema merge when the value types are compatible. At scan time, the parquet opener passes the promoted schema to arrow-rs so those columns can be read as dictionary arrays directly.

Tables with a user-supplied schema are not promoted because DataFusion does not use footer metadata to infer their schema.

Are these changes tested?

yes.

datafusion/sqllogictest/test_files/parquet_rle_to_dictionary.slt
datafusion/datasource-parquet/src/schema_coercion.rs
- uniform_dict_schemas_respects_value_type_families checks that mixed file schemas are normalized only across compatible string/binary families.
- rle_schema_coercion_respects_dictionary_value_type checks scan-time coercion into dictionary types, including incompatible cases and the flag-off path.
datafusion/datasource-parquet/src/opener/mod.rs
- test_rle_binary_column_promotion verifies the opener passes a promoted Dictionary(Int32, Binary) schema to arrow-rs so binary columns can be read as dictionary arrays directly.

Are there any user-facing changes?

New session config option: SET datafusion.execution.parquet.enable_rle_to_dictionary = true. Default is false so existing behavior is unchanged.

@adriangb pinging you since you seem interested in parquet related speed ups 👍

adriangb · 2026-08-13T12:49:06Z

If I understand correctly the goal is to evaluate filters during filter pushdown against dictionary / RLE encoded columns? We can't propagate these dynamic type changes to the rest of the query plan / scan. Is that right?

no not exactly. The goal of this PR is to keep RLE parquet columns in their compacted form by materializing them as dictionary arrays instead of regular strings.

We can't propagate these dynamic type changes to the rest of the query plan / scan. Is that right?

exactly! This is why it needs to be done as early in the plan as possible. we inspect DFParquetMetadata::fetch_schema to see if any RLE columns exist, if so change the plan type from utf8/binary to dict<_,utf8/binary>. Thanks to some plumbing in arrow-rs it will handle the conversions correctly returning a dictionary array, this can cause a 60x perf boost

Why only RLE and not dictionaries as well? How does this compare to / relate to the schema_force_view_types option?

It also looks like this goes through infer_schema right? A lot of code paths never touch that (CREATE EXTERNAL TABLE (a VARCHAR), any custom table providers, etc.).

I'd be more interested in seeing something at the parquet scan level that was able to e.g. optimize how row filters are applied by applying them to the dictionary instead of expanding into Utf8View. That would be applicable to all DataFusion users.

my bad when I say RLE i'm referring to RLE_DICTIONARY

I agree, ill update the PR to target all parquet scans.

Rich-T-kid · 2026-08-13T18:59:51Z

ideally we surface columns that are physically RLE_DICTIONARY-encoded in the parquet file as Arrow Dictionary(Int32, Utf8) arrays rather than decoding them back to plain Utf8.

To know whether a specific column is RLE_DICTIONARY-encoded you need to read the parquet file footer. For the infer_schema path this happens at table registration, but for explicit schemas (CREATE EXTERNAL TABLE (col VARCHAR)) and direct ParquetSource construction no footer is ever read during planning, so per-column encoding information isn't available for all paths.

Downstream physical operators (FilterExec, AggregateExec) are compiled against the scan's declared output schema during physical planning, before any files are opened. If the scan declares Utf8 but produces Dictionary(Int32, Utf8) at execution time that's a type mismatch.

So when the flag is enabled we promote all string/binary columns to dict at planning time, not just the ones that are actually RLE-encoded, because that's the only way to guarantee schema consistency across all parquet scan paths without introducing file I/O into the planning stage.

I feel like i'm missing something here. if we could take a peak at the parquets metadata before physical planning and change the schema for all operators from the point forward that would be perfect. Im not sure this is currently possible

Rich-T-kid · 2026-08-14T17:35:56Z

@adriangb When the flag is on, DataFusion promotes string and binary columns that are physically RLE_DICTIONARY encoded in the parquet file to Dictionary(Int32, Utf8) or Dictionary(Int32, Binary) at schema inference time. This applies to all parquet scans regardless of how the table was registered.

the PR is ready for review

Rich-T-kid · 2026-08-15T05:05:51Z

How does this compare to / relate to the schema_force_view_types option?

utf8 columns become dict<_,utf8 so the default string type for parquet columns utf8View is replaced.

thank you for the review @kumarUjjawal, I implemented all of you suggestions in 6b75dcf. everything related to the per-column allowlist has been removed

…ssion in schema coercion - Drop rle_column_allowlist from ParquetFormat and DFParquetMetadata: no callers existed and new public API is hard to remove post-release - Remove Dictionary arm from transform_schema_to_view and transform_binary_to_string: those arms fired unconditionally regardless of enable_rle_to_dictionary, causing pre-existing dict columns to get wrong value types when the flag was off - Remove the unit test that covered the now-deleted transform_binary_to_string dict arm - Drop Utf8View/BinaryView arms added to common_dictionary_value_type: the parquet reader never produces view types in the physical file schema so they were dead code - Clean up parquet_rle_to_dictionary.slt: remove redundant SET and spurious RESET
