  • Which issue does this PR close?

    Rationale for this change

    This PR adds a configurable optimizer rewrite for UNION DISTINCT queries. The goal is to allow the optimizer to collapse eligible union branches into a single filtered scan when the branches read from the same source and differ only by filter predicates.

    This optimization can reduce duplicated work and avoid scanning the same input multiple times. Keeping it behind a configuration flag makes the behavior explicit and safe to enable only when desired.

    What changes are included in this PR?

    • Adds a new optimizer configuration option: datafusion.optimizer.enable_unions_to_filter, which is disabled by default.
    • Enables the UnionsToFilter optimization rule in the logical optimizer pipeline.
    • Adds documentation for the new configuration option, including plan-shape examples.
    • Extends sqllogictest coverage in datafusion/sqllogictest/test_files/union.slt to cover both the disabled and enabled cases.
    • Verifies that the rewrite only applies to eligible UNION DISTINCT queries.

    Example rewrite

    When the rule is enabled, a query such as:

    SQL

    SELECT id, name FROM t1 WHERE id = 1
UNION
SELECT id, name FROM t1 WHERE id = 2

    may be rewritten into an equivalent plan that scans t1 once and applies a combined filter such as:

    SQL

    SELECT id, name FROM t1 WHERE id = 1 OR id = 2

    This keeps the results unchanged while avoiding repeated reads from the same source.

    Are these changes tested?

    Yes.

    The new behavior is covered by sqllogictest cases that validate both plan variants:

    • the original UNION DISTINCT execution path when the option is disabled
    • the rewritten single-scan plan when the option is enabled

    Are there any user-facing changes?

    Yes.

    A new configuration option is introduced:

    • datafusion.optimizer.enable_unions_to_filter

    When enabled, some UNION DISTINCT queries may be optimized into a different plan shape. Query results remain the same, but the execution plan may change.

Hi @alamb , here's another PR related to plan optimization. Do we need it? I'd also like to know what aspects of optimization we accept.

Hi @Dandandan , I noticed that you’re very knowledgeable about SQL optimization. It would be great if you could help me review this!

@xiedeyantu -- can you please file a ticket explaining what usecase you are targeting with this optimization?

Your explanation in

Rationale for this change

Mostly focuses on "what" is changed, not the "why"

In terms of usecase I think what is important:

  1. Example SQL queries that show the pattern you are optimizing for

Then for this optimization it would be great to have some benchmark numbers showing that the query of interest iindeed gets faster with this optimization compared than without it

@alamb Here is an example: There is a rule for eliminating UNION under specific conditions. It applies when the branches of the UNION come from the same table and only differ in their WHERE conditions. This rule allows us to avoid an extra table scan — we only need to perform a single combined conditional filter.

I haven't looked at the proposed implementation but the rewrite can surely help in case of repeated costly union branches (especially when coming from possibly complex data sources powered via TableProvider).

It seems also particularly relevant until #8777 gets addressed (broader scope, CTE materialization), as currently there is no other way to mutualize repeated reads AFAIK.

Thank you @asolimando , for connecting me to such a valuable discussion. I think the idea in #8777 is excellent, but it seems we might need to perform a union operation once more. It looks like a final conclusion hasn't been reached yet? However, this approach can support UNION ALL. It seems the two might complement each other?

I tested the execution times, and in reality, the difference between the two was not significant. My understanding is that the multiple branches within a UNION operation can be processed in parallel; therefore, one would not expect to see a substantial reduction in overall execution time (and if a significant improvement were observed, it would likely indicate an issue elsewhere). Consequently, I had to rely on EXPLAIN ANALYZE to inspect the execution plan, thereby demonstrating that—prior to optimization—the data required two separate scans, whereas after optimization, only a single scan was necessary.

The test SQL script is as follows:

# test_data.csv
id,category,amount,created_at
1,A,10,2026-03-29 00:00:01
2,B,20,2026-03-29 00:00:02
3,C,30,2026-03-29 00:00:03
......
9999,D,99990,2026-03-29 02:46:39
10000,E,100000,2026-03-29 02:46:40

# create table
CREATE EXTERNAL TABLE t (
  id INT,
  category STRING,
  amount INT,
  created_at TIMESTAMP
)
STORED AS CSV
LOCATION 'test_data.csv'

  has_header 'true'
);

I would agree with @alamb to create initial ticket stating the problem. PR description is nice but it is a solution whereas ticket is a problem statement and some people could also participate in problem discussion

@comphead Apologies—I may not have fully understood the process earlier; I thought simply describing the issue within the PR itself (including both the problem and the proposed solution) would suffice. I have now created a new issue #21310 for everyone to discuss. Please take a look and let me know if it looks appropriate.

Thanks @xiedeyantu I'll take a look this week, would be super useful for users and also for regression to have internal microbenchmarks, similar to datafusion/core/benches/push_down_filter.rs

we can combine those 2 branches, or ideally to trace the reason why rewrite was skipped for each condition

considering all the introduced guardrails it would probably be useful adding some debug info why the optimizer rule cannot be applied

Thanks @xiedeyantu for this PR, I think we need to run current tests with this optimizer rule on. The easiest way to proceed if you enable the rule by default in this PR so we can run CI and also benchmarks to get some data points and then disable the rule

@comphead Thank you for your detailed review. I will immediately address these issues based on your comments and temporarily set the parameter to true.

Hi @comphead, run benchmark requires benchmark names (#21075 (comment)).

Supported benchmarks:

  • Standard: clickbench_1, clickbench_extended, clickbench_partitioned, clickbench_pushdown, external_aggr, smj, sort_pushdown, sort_pushdown_sorted, tpcds, tpch, tpch10, tpch_mem, tpch_mem10
  • Criterion: (any)

Usage:

run benchmark <name>           # run specific benchmark(s)
run benchmarks                 # run default suite
run benchmarks <name1> <name2> # run specific benchmarks

Per-side configuration (run benchmark tpch followed by):

env:
SHARED_SETTING: enabled
baseline:
ref: v45.0.0
env:
DATAFUSION_RUNTIME_MEMORY_LIMIT: 1G
changed:
ref: v46.0.0
env:
DATAFUSION_RUNTIME_MEMORY_LIMIT: 2G
