Covers:\n\n- Why SortExec is expensive and what `Exact` / `Inexact` ordering mean\n at runtime (static `fetch` vs `TopK` dynamic filter).\n- Phase 1 (#19064): the `PushdownSort` rule + reverse row-group case.\n- Phase 2 (#21182): statistics-based file sort that upgrades\n `Unsupported` to `Exact`, eliminating the `SortExec` on\n non-overlapping ASC scans. Includes the BufferExec compensation\n (#21426) so the SPM above doesn\u0027t lose its implicit memory buffer.\n- Reverse scans: today\u0027s row-group reverse (Inexact, #18817) and the\n community decision to wait for arrow-rs page-level reverse (#9937)\n before pursuing Exact reverse, after memory-profile pushback on the\n original row-group-level proposal.\n- Benchmarks: 2.1×-49× on the ASC-LIMIT sort_pushdown suite.\n- What\u0027s next: the dynamic / TopK-driven path (#21351 merged, #21733,\n #21712, #21956, #21580) including the precise RG-pruning vs\n mid-stream-early-return distinction, and the EnsureRequirements\n unification (#21976).\n- Links into the prior dynamic filters and limit pruning posts so the\n series reads as a coherent thread.\n\n* Push draft date to 2026-05-25\n\n* Add Phase 3 section covering #21956 runtime reorder pipeline\n\nThe post previously only mentioned #21956 in passing. The PR is\nlanding the full mechanism — `try_pushdown_sort` decision tree,\ntwo flags on `ParquetSource`, three composable runtime steps\n(file reorder + RG reorder + reverse), and a `sort_prefix`-\npreserving short-circuit — so cover it as a dedicated phase\nbetween Phase 2 and the existing reverse-scan section.\n\n- TL;DR: add a Phase 3 bullet alongside Phase 1 and Phase 2.\n- Phase 1: replace the in-flight `#21956` aside with a cross-link\n to the new section.\n- Phase 2: keep the caveat about function-wrapped sorts but note\n that #21956\u0027s `Inexact` path now covers them via monotonicity\n inference.\n- New `## Phase 3` section with two SVG diagrams: a decision tree\n for the three protocol outcomes, and a three-step pipeline for\n the `Inexact` runtime. Covers the two-flag design, the nested\n file/RG layers, when EXPLAIN surfaces each flag, and four\n scenarios where Phase 3 does not fire (aggregations, multi-\n column secondary keys, function-wrapped sorts without a\n declared ordering, source declares a forward prefix of the\n request).\n- \"What\u0027s Next\": rename the old \"Phase 3 — filter + sort\" bullet\n to \"Filtered reverse TopK end-to-end\" so the label doesn\u0027t\n clash with the new section, and add a follow-up bullet\n referencing #22198 for multi-column / function-wrapped reorder.\n\n* Add empirical note: why we keep an out-of-tree RG-level Exact reverse\n\nAdd an ### Empirical note subsection inside \"Reverse Scans for\n`ORDER BY ... DESC`\" that records what we found running an in-house\nRG-level `Exact` reverse against upstream `Inexact` + `TopK`:\n\n- `LIMIT N` does not propagate as a static stop signal in the\n Inexact path. The dynamic filter pushdown can stats-prune\n *subsequent* row groups once the threshold tightens, but inside\n the row group `TopK` is currently reading the sort column has to\n be fully decoded so the filter can be evaluated row by row.\n `LIMIT 10` on a 1M-row row group is still ~1M sort-column\n decodes regardless of N. LIMIT only saves work on non-sort\n columns inside that row group and on whole subsequent row\n groups the threshold prunes.\n- `SortExec` stays on top of `Inexact`, so the final ordering\n pass and per-row heap maintenance are both extra costs the\n `Exact` path (which deletes `SortExec`) does not pay.\n\nThen explain why we run RG-level `Exact` in production but did\nnot upstream it: parquet does not allow partial row-group reads,\nso any RG-level `Exact` implementation peaks at one whole row\ngroup (~128 MB) of decoded data in memory — the same constraint\nthat closed `#18817`. Our runtime advantage comes from skipping\nheap / filter / `SortExec` overhead, not from decoding less.\n\nFrame the page-level `Exact` reverse work in arrow-rs `#9937` as\nthe path that keeps the runtime win we measured while bringing\npeak memory back into the streaming regime via `OffsetIndex`\npage-level seek.\n\n* Correct internal RG-Exact description and trim arrow-rs #9937 duplication\n\nTwo corrections in the empirical-note / reverse-scans section:\n\n1. The internal RG-level `Exact` reverse path was incorrectly\n described as \"walks pages from the back, decodes each batch,\n reverses row-wise, stops the moment K rows have been delivered.\"\n That is actually the page-level `Exact` shape (arrow-rs #9937),\n not the in-house RG-level implementation. Parquet does not allow\n partial row-group reads, so the in-house path has to decode the\n entire target row group, reverse the buffer in memory, take the\n first K rows, and stop — same memory profile as #18817\u0027s\n proposal. The runtime advantage over `Inexact` + `TopK` comes\n from removing the per-row heap maintenance, dynamic-filter\n evaluation, and `SortExec` final ordering pass, not from\n decoding less sort-column data. Sort col decode on the target\n row group is the same on both paths.\n\n2. The arrow-rs #9937 paragraph I previously added duplicated the\n technical detail already present in the long-standing\n \"That primitive is the page-level reverse traversal...\"\n paragraph. Replaced with a one-sentence bridge (\"The fix that\n keeps both the runtime win and a streaming memory profile is\n page-level `Exact` reverse via arrow-rs #9937, described next.\")\n so the existing paragraph carries the explanation without\n repetition.\n\n* Mark #21956 as landed (merged via merge queue)\n\n* Reframe blog from Phase N → capability-based sections\n\nAll three sort-pushdown PRs have now landed, so the chronological\n\u0027Phase 1/2/3\u0027 framing is less useful for readers than a capability\nbreakdown. Sections are now:\n- The PushdownSort Rule (#19064)\n- Sort Elimination via Statistics (#21182)\n- Runtime Reorder for TopK Convergence (#21956)\n- Reverse Scans for ORDER BY ... DESC (unchanged)\n\nIn-body Phase references replaced with PR numbers or capability names;\nanchor links updated; references section restructured.\n\n* Clarify two-layer composability: same key (min), not \u0027nest by construction\u0027\n\nThe previous wording \u0027nest by construction\u0027 could be read as a code-\nenforced property. It\u0027s actually a logical consequence of using the\nsame sort key (min) at both file and row-group level: a file\u0027s\nmin(col) is just the minimum over its row groups\u0027 min(col) values, so\nthe most-promising file contains the most-promising row group. The\nrewritten paragraph spells that out and ties it to why TopK\u0027s dynamic\nfilter tightens fast.\n\n* Strip inline PR refs from narrative; collect all links in References\n\nMatch the dynamic-filter blog\u0027s style: narrative talks about\ncapabilities/mechanisms, not \u0027PR #21956 did X / PR #19064 introduced\nY\u0027. The 81 inline PR/issue references in the body were dropping the\nreader out of the narrative; they belong in a single Issues-and-PRs\nlist at the end.\n\nChanges:\n- TL;DR: drop 6 inline PR refs from the 4 capability bullets\n- Body sections (PushdownSort Rule, Sort Elimination, Runtime Reorder,\n Reverse Scans, Empirical Note): drop ~30 inline refs to historical\n PRs; replace with capability names or \u0027the rule\u0027 / \u0027the runtime\n reorder path\u0027 style descriptions\n- What\u0027s Next: switch from [#NNNNN] format to named markdown links\n (matching dynamic-filter\u0027s Future Work style)\n- Issues for new contributors: same conversion\n- References section: rewrite using full URLs (no link-ref\n indirection); split into \u0027Landed\u0027 vs \u0027In flight / open\u0027 for\n clarity\n\nNet: ~90 lines removed, all PR/issue numbers now consolidated at\nthe bottom of the post.\n\n* Restructure: split into merged-features / bottlenecks / roadmap\n\nThe previous draft mixed merged work, in-flight work, and runtime-cost\nanalysis into a single \u0027Reverse Scans\u0027 section and a sprawling \u0027What\u0027s\nNext\u0027 section. Reorganize so the post answers three clear questions in\nsequence:\n\n1. What\u0027s merged today? (Sort Elimination via Statistics + benchmark,\n Runtime Reorder for TopK Convergence, Reverse Scans for DESC) —\n unchanged content, just kept tight.\n2. Where do those merged features still leave performance on the\n table? New \u0027Current Bottlenecks\u0027 section with three explicitly\n numbered bottlenecks: SortExec stays / sort column fully decoded\n inside open RG / file-granular scheduling can\u0027t close the tap\n mid-file. Pulls in the runtime-cost content that used to be buried\n in an \u0027Empirical note\u0027 subsection.\n3. How does each next-step optimization remove a specific bottleneck?\n New \u0027Roadmap\u0027 section maps page-level Exact reverse to bottlenecks\n 1+2, row-group-level dynamic early termination to bottleneck 3, and\n shows the in-flight 17x-60x pipeline benchmark as a preview of what\n stacking these mechanisms can deliver.\n\nSmaller follow-ups (EnsureRequirements, OFFSET pushdown, multi-column\nreorder) collected at the end of the roadmap section as a short\n\u0027Other follow-ups\u0027 bullet list.\n\n* Tighten verbose paragraphs; drop unrelated limit-pruning blog reference\n\n- \u0027Why not full Exact reverse\u0027 paragraph: cut reviewer attribution and\n forward-pointers that were already in the bottleneck/roadmap\n sections that follow.\n- TL;DR: trim Runtime Reorder + Reverse Scans bullets to capability\n and impact; drop implementation mechanics like \u0027stamps two flags\u0027\n and \u0027three-step pipeline\u0027.\n- \u0027The PushdownSort Rule\u0027 section: cut three paragraphs of\n \u0027covered in X below\u0027 forward-references that were repeating\n the section TOC.\n- Function-wrapped parenthetical in Sort Elimination: 4 lines to 2.\n- Single-partition vs multi-partition edge case: drop the trailing\n \u0027which is why the example is drawn that way\u0027 tangent.\n- \u0027What this change does not affect\u0027 note: trimmed redundant prose.\n- Remove all references to the limit-pruning blog (intro mention,\n link definition, References section bullet) — that work is about\n static LIMIT as an I/O optimization, separate problem from sort\n ordering.\n\n* Fold reverse as case of Inexact runtime reorder; make two-trigger asymmetry explicit\n\nPer code in datasource-parquet/src/source.rs:849-870, the reversed-\nsatisfies branch is \u0027strictly more powerful than the column-in-schema\ncheck\u0027 — it runs the request through EquivalenceProperties\u0027s full\nreasoning machinery and handles function monotonicity, constants from\nfilters, equivalence relationships, and multi-column composite\norderings. The blog had been treating reverse as just step 3 of the\nruntime pipeline, which undersold its standalone reach.\n\nStructural changes:\n- Drop the standalone \u0027Reverse Scans for ORDER BY DESC\u0027 H2 section;\n reverse is now a case of the Inexact runtime reorder path.\n- Rename Runtime Reorder section to \u0027Runtime Reorder for TopK and\n DESC Queries\u0027; intro now lists three classes that fall outside\n Exact (unsorted, overlapping, DESC).\n- \u0027try_pushdown_sort\u0027 subsection rewritten as \u0027Two independent\n triggers for Inexact\u0027, describing column-in-schema vs reversed-\n satisfies as separate signals with the latter being strictly more\n powerful.\n- \u0027Three runtime steps\u0027 subsection: step 3 now explicitly notes when\n steps 1-2 are skipped and only the iteration reverse runs.\n- New \u0027ORDER BY DESC in practice\u0027 subsection right after the 3-step\n pipeline, explaining the RGs-descending-x-rows-ascending stream.\n- Move reverse-scan.svg from the deleted Reverse Scans section into\n the Roadmap \u003e Page-level Exact reverse subsection where it\n illustrates the 128 MB vs 1 MB peak comparison directly.\n\nAccuracy fix:\n- \u0027Multi-column reorder follow-ups\u0027 bullet was inaccurate — said the\n reorder \u0027only fires on plain columns\u0027. The reverse path does\n handle function-wrapped and multi-column cases via\n EquivalenceProperties; only the stats reorder step is restricted.\n Updated wording to scope the limitation correctly.\n\n* Drop EnsureRequirements + OFFSET pushdown — both unrelated to sort pushdown\n\nEnsureRequirements (#21976) is a rule-unification effort for\nEnforceDistribution+EnforceSorting. Touches the same area but isn\u0027t\na sort pushdown optimization.\n\nOFFSET pushdown (#21828) is about LIMIT/OFFSET pruning. Same kind of\ntangent as the limit-pruning blog reference removed earlier — it\u0027s\nLIMIT optimization, not sort pushdown.\n\nThe remaining \u0027Multi-column and function-wrapped reorder follow-ups\u0027\nbullet is actually directly about sort pushdown\u0027s reorder step\n(#22198), so it stays. With the other two removed, \u0027Other follow-ups\u0027\ncollapsed to a single point — promoted to its own subsection\n\u0027Extending the stats reorder step\u0027 for clarity.\n\nAlso dropped the corresponding entries from the References section.\n\n* Roadmap RG-level early termination: split into non-overlap vs overlap (k-way merge)\n\nThe \u0027switch work queue from PartitionedFile to RG descriptors\u0027 fix is\nsufficient for non-overlapping ranges (post-reorder), where the first\nfile globally has the smallest values and subsequent files are\nalready stats-pruned. For overlapping ranges, the next smallest value\ncould sit in any of several open files — matching the non-overlap\nefficiency requires explicit k-way merge across open files\u0027 next-RG\nmins. The dynamic filter does this implicitly (RGs with max \u003c threshold\nare dropped), but explicit comparison closes the tap earlier when the\nfilter tightens slowly.\n\n* Rewrite blog around #22450: three-layer pruning + topk_tpch headline\n\nRestructure the post so the merged Runtime Row-Group Dynamic Pruning\n(#22450) is the centerpiece, matching the community-talk narrative:\n\n- TL;DR now leads with the three-layer pruning stack (file + RG + row)\n and the topk_tpch headline (5/11 queries 3-4x, 0 regressions, -44%\n total).\n- Exact path keeps credit attribution explicit: EnforceSorting already\n handled the simple on-disk-sorted case; Phase 2 closes the\n wrong-on-disk-order gap. BufferExec story expanded with the SPM\n stall diagnosis.\n- Inexact path split into Tier 1 (file-level, already had early stop)\n vs Tier 2 (RG-level, no early stop until #22450) so the gap that\n #22450 closes is named explicitly.\n- New section: #22450 mechanics - architecture-3-eras, transition()\n drain/decide/drive, RowGroupPruner watch/rebuild/prune, cascading\n prune walkthrough.\n- New section: Three-layer pruning stack with the same DynamicFilter\n driving all three layers, plus the topk_tpch benchmark table.\n- Old \"Current Bottlenecks\" + \"Roadmap\" merged into \"Future Directions\":\n A) page-level Exact reverse (arrow-rs #9937), B) page-level dynamic\n prune at RG boundary (#23216).\n- Updated landed-PRs list to include #20839 (push-based decoder, the\n prerequisite for #22450) and #22450 itself.\n\nPulls in 9 PNGs from the community-call deck for the #22450-specific\ndiagrams (architecture, transition, pruner, cascade, three-layer stack,\ntopk_tpch results, page-level future).\n\n* Update content/blog/2026-07-05-sort-pushdown.md\n\nCo-authored-by: Andrew Lamb \u003candrew@nerdnetworks.org\u003e\n\n* Update content/blog/2026-07-05-sort-pushdown.md\n\nCo-authored-by: Andrew Lamb \u003candrew@nerdnetworks.org\u003e\n\n* Update content/blog/2026-07-05-sort-pushdown.md\n\nCo-authored-by: Andrew Lamb \u003candrew@nerdnetworks.org\u003e\n\n* Update content/blog/2026-07-05-sort-pushdown.md\n\nCo-authored-by: Andrew Lamb \u003candrew@nerdnetworks.org\u003e\n\n* Update content/blog/2026-07-05-sort-pushdown.md\n\nCo-authored-by: Andrew Lamb \u003candrew@nerdnetworks.org\u003e\n\n* Update content/blog/2026-07-05-sort-pushdown.md\n\nCo-authored-by: Andrew Lamb \u003candrew@nerdnetworks.org\u003e\n\n* Update content/blog/2026-07-05-sort-pushdown.md\n\nCo-authored-by: Andrew Lamb \u003candrew@nerdnetworks.org\u003e\n\n* Address alamb review round 2 (46 comments)\n\nTighten intro to be engine-agnostic and drop time-tied phrasing; use\nplain \u0027sort\u0027 instead of SortExec in engine-agnostic sections while\nkeeping SortExec in DataFusion-internals sections.

Since the surrounding\nmarkdown text already covers the drain/decide/drive loop and the\nwatch/rebuild/prune pipeline, dropping the figures resolves both\nconcerns without losing content.\n\n* Revert \"Remove transition_anatomy and pruner_loop figures\"\n\nThis reverts commit 9b48aa84dff0155731da614bdf1eea5904089a6f.\n\n* Regenerate transition_anatomy and pruner_loop figures\n\nAddress alamb\u0027s figure-annotation feedback:\n\ntransition_anatomy.png:\n- Widened Step 2 / Step 3 code boxes so `into_builder().with_row_groups(...)`\n and `Data -\u003e set_active_reader` fit inside their boxes without overflow.\n- Removed the bottom captions that duplicated content already in the blog text.\n\npruner_loop.png:\n- Widened WATCH shape so `1 atomic load` fits without cutoff.\n- Removed the `Errors fall back to keep` line (too much detail per alamb).\n- Same three shapes + arrows + descriptor cards; only sizing tweaked.\n\n* Move Three-Layer Pruning section earlier\n\nPer alamb\u0027s suggestion in #3544371141 — moved the multi-layer pruning\nstrategy section from after Runtime Row-Group Dynamic Pruning to right\nafter How DataFusion Tracks Ordering, so readers see the overall\nframework (three layers, one dynamic filter) before diving into each\nlayer\u0027s implementation. Reworded the opener from \u0027sort-based\noptimizations described above\u0027 to \u0027techniques described below\u0027 since\nit\u0027s now leading rather than summarizing.

filters\n\nCo-authored-by: Yongting You \u003c2010youy01@gmail.com\u003e\n\n* Address a variety of user feedback\n\n* Update links\n\n* pelican processing didn\u0027t handle backticks in links well\n\n* Add an explanation of different ways to use FileFormat for a ListingTable\n\n* Address alamb review feedback\n\n- Clarify intro sentence to mention planning/execution work\n- Label TableProvider as Logical Plan and ExecutionPlan as Physical Plan\n- Change \"four phases\" to \"several phases\" (list has 5 items)\n- \"Some logical optimizations\" and \"rewrites such as\" to signal non-exhaustive lists\n- Clarify scan() comment: \"don\u0027t do any execution work here\"\n- Rewrite partitioning section to lead with simple advice (match data layout)\n before covering target_partitions and hash partitioning subtleties\n- Narrow CPU thread pool advice: spawn_blocking is for blocking/long-running\n work, not all CPU work\n- Add \"scan is single-threaded\" as a reason to keep scan() lightweight\n\nCo-Authored-By: Claude Sonnet 4.6 \u003cnoreply@anthropic.com\u003e\n\n* update date\n\n* Add link to thread_pools example for blocking work section\n\nCo-Authored-By: Claude Sonnet 4.6 \u003cnoreply@anthropic.com\u003e\n\n* remove use statements from example\n\n* revert section on scan_with_args and drop to single line\n\n* Move \u0027Choosing the Right Starting Point\u0027 before Layer 1\n\nAddresses alamb\u0027s suggestion to move the section earlier so readers\nunderstand what level of work is required before diving in.\n\n- Moved section to just before Layer 1: TableProvider\n- Trimmed the file-based path detail to a short paragraph with links\n (the full trait hierarchy was too deep for an intro-position section)\n- Removed RecordBatchStreamAdapter reference (not yet introduced at\n that point in the article)\n- Added a sentence orienting the reader to what the rest of the post covers\n\nCo-Authored-By: Claude Sonnet 4.6 \u003cnoreply@anthropic.com\u003e\n\n* Fix pre-publish review issues\n\n- Fix use-after-move bug in DatePartitionedExec construction (dirs.len()\n called after dirs moved into struct field)\n- Fix incorrect import: SessionState → catalog::Session in CountingTable\n example\n- Remove double space before scan_with_args link\n- Add missing blank line before \u0027### Using EXPLAIN\u0027 heading\n- Split dense \u0027Only Push Down Filters\u0027 paragraph for readability\n- Change \u0027full working example\u0027 to \u0027illustrative example\u0027 for the\n filter pushdown code that contains todo!() stubs\n- Use \u0027Rerun is building\u0027 instead of repeating [Rerun.io] link\n\nCo-Authored-By: Claude Sonnet 4.6 \u003cnoreply@anthropic.com\u003e\n\n* Add reviewer acknowledgements to

Final pre-publish fixes\n\n- Fix grammar: \"Best practices are\" → \"Best practice is\"\n- Remove unused StringArray import from complete example\n- Fix outdated arrow-datafusion repo link → apache/datafusion\n- Add missing reviewers to acknowledgements: adriangb, kevinjqliu, Omega359\n\nCo-Authored-By: Claude Sonnet 4.6 \u003cnoreply@anthropic.com\u003e\n\n* make it
