d26d6c34fc Fix select_nth_unstable_by_key midpoint duplicates.
Existing code behaved as if the result of `select_nth_unstable_by_key`
was either a sorted array or the product of an algorithm that gathered
partition values as in the Dutch national flag problem. The existing
code was written knowing that the former isn't true and the latter isn't
advertised. Knowing, but not remembering. Quite the oversight.

6da54fa5da Revert "Remove radix_select.rs."
This reverts commit 19eab167b6.

Restore radix select in order to implement a merge solution that will
not require a temporary file.

9f10279681 Complete Spatial/Geometry type integration.
Addressed all `todo!()` markers created when adding `Spatial` field type
and `Geometry` value type to existing code paths:

- Dynamic field handling: `Geometry` not supported in dynamic JSON
  fields, return `unimplemented!()` consistently with other complex
  types.
- Fast field writer: Panic if geometry routed incorrectly (internal
  error.)
- `OwnedValue` serialization: Implement `Geometry` to GeoJSON
  serialization and reference-to-owned conversion.
- Field type: Return `None` for `get_index_record_option()` since
  spatial fields use BKD trees, not inverted index.
- Space usage tracking: Add spatial field to `SegmentSpaceUsage` with
  proper integration through `SegmentReader`.
- Spatial query explain: Implement `explain()` method following pattern of
  other binary/constant-score queries.

Fixed `MultiPolygon` deserialization bug: count total points across all
rings, not number of rings.

Added clippy expects for legitimate too_many_arguments cases in geometric
predicates.

68009bb25b Read block kd-tree nodes using from_le_bytes.
Read node structures using `from_le_bytes` instead of casting memory.
After an inspection of columnar storage, it appears that this is the
standard practice in Rust and in the Tantivy code base. Left the
structure alignment for now in case it tends to align with cache
boundaries.

459456ca28 Remove radix_select.rs.
Ended up using `select_nth_unstable_by_key` from the Rust standard
library instead.

dbbc8c3f65 Slot block kd-tree into Tantivy.
Implemented a geometry document field with a minimal `Geometry` enum.
Now able to add that Geometry from GeoJSON parsed from a JSON document.
Geometry is triangulated if it is a polygon, otherwise it is correctly
encoded as a degenerate triangle if it is a point or a line string.
Write accumulated triangles to a block kd-tree on commit.

Serialize the original `f64` polygon for retrieval from search.

Created a query method for intersection. Query against the memory mapped
block kd-tree. Return hits and original `f64` polygon.

Implemented a merge of one or more block kd-trees from one or more
segments during merge.

Updated the block kd-tree to write to a Tantivy `WritePtr` instead of
more generic Rust I/O.

d3049cb323 Triangulation is not just a conversion.
The triangulation function in `triangle.rs` is now called
`delaunay_to_triangles` and it accepts the output of a Delaunay
triangulation from `i_triangle` and not a GeoRust multi-polygon. The
translation of user polygons to `i_triangle` polygons and subsequent
triangulation will take place outside of `triangle.rs`.

ccdf399cd7 XOR delta compression for f64 polygon coordinates.
Lossless compression for floating-point lat/lon coordinates using XOR
delta encoding on IEEE 754 bit patterns with variable-length integer
encoding. Designed for per-polygon random access in the document store,
where each polygon compresses independently without requiring sequential
decompression.

2dc46b235e Implement block kd-tree.
Implement an immutable bulk-loaded spatial index using recursive median
partitioning on bounding box dimensions. Each leaf stores up to 512
triangles with delta-compressed coordinates and doc IDs. The tree
provides three query types (intersects, within, contains) that use exact
integer arithmetic for geometric predicates and accumulate results in
bit sets for efficient deduplication across leaves.

The serialized format stores compressed leaf pages followed by the tree
structure (leaf and branch nodes), enabling zero-copy access through
memory-mapped segments without upfront decompression.

f38140f72f Add delta compression for block kd-tree leaf nodes.
Implements dimension-major bit-packing with zigzag encoding for signed i32
deltas, enabling compression of spatially-clustered triangles from 32-bit
coordinates down to 4-19 bits per delta depending on spatial extent.
2025-12-01 16:48:32 +01:00
Alan Gutierrez
0996bea7ac Add a surveyor to determine spread and prefix.
Implemented a `Surveyor` that will evaluate the bounding boxes of a set
of triangles and determine the dimension with the maximum spread and the
shared prefix for the values of dimension with the maximum spread.

1c66567efc Radix selection for block kd-tree partitioning.
Implemented byte-wise histogram selection to find median values without
comparisons, enabling efficient partitioning of spatial data during
block kd-tree construction. Processes values through multiple passes,
building histograms for each byte position after a common prefix,
avoiding the need to sort or compare elements directly.

b2a9bb279d Implement polygon tessellation.
The `triangulate` function takes a polygon with floating-point lat/lon
coordinates, converts to integer coordinates with millimeter precision
(using 2^32 scaling), performs constrained Delaunay triangulation, and
encodes the resulting triangles with boundary edge information for block
kd-tree spatial indexing.

It handles polygons with holes correctly, preserving which triangle
edges lie on the original polygon boundaries versus internal
tessellation edges.

558c99fa2d Triangle encoding for spatial indexing.
Encodes triangles with the bounding box in the first four words,
enabling efficient spatial pruning during tree traversal without
reconstructing the full triangle. The remaining words contain an
additional vertex and packed reconstruction metadata, allowing exact
triangle recovery when needed.

name: rationalize-deps
description: Analyze Cargo.toml dependencies and attempt to remove unused features to reduce compile times and binary size
---
# Rationalize Dependencies
This skill analyzes Cargo.toml dependencies to identify and remove unused features.
## Overview
Many crates enable features by default that may not be needed. This skill:
1. Identifies dependencies with default features enabled
2. Tests if `default-features = false` works
3. Identifies which specific features are actually needed
4. Verifies compilation after changes
## Step 1: Identify the target
Ask the user which crate(s) to analyze:
- A specific crate name (e.g., "tokio", "serde")
- A specific workspace member (e.g., "quickwit-search")
- "all" to scan the entire workspace
## Step 2: Analyze current dependencies
For the workspace Cargo.toml (`quickwit/Cargo.toml`), list dependencies that:
- Do NOT have `default-features = false`
- Have default features that might be unnecessary
Run: `cargo tree -p <crate> -f "{p} {f}" --edges features` to see what features are actually used.
## Step 3: For each candidate dependency
### 3a: Check the crate's default features
Look up the crate on crates.io or check its Cargo.toml to understand:
- What features are enabled by default
- What each feature provides
Use: `cargo metadata --format-version=1 | jq '.packages[] | select(.name == "<crate>") | .features'`
### 3b: Try disabling default features
Modify the dependency in `quickwit/Cargo.toml`:
From:
```toml
some-crate = { version = "1.0" }
```
To:
```toml
some-crate = { version = "1.0", default-features = false }
```
### 3c: Run cargo check
Run: `cargo check --workspace` (or target specific packages for faster feedback)
If compilation fails:
1. Read the error messages to identify which features are needed
2. Add only the required features explicitly:
```toml
some-crate = { version = "1.0", default-features = false, features = ["needed-feature"] }
```
3. Re-run cargo check
### 3d: Binary search for minimal features
If there are many default features, use binary search:
1. Start with no features
2. If it fails, add half the default features
3. Continue until you find the minimal set
## Step 4: Document findings
For each dependency analyzed, report:
- Original configuration
- New configuration (if changed)
- Features that were removed
- Any features that are required
## Step 5: Verify full build
After all changes, run:
```bash
cargo check --workspace --all-targets
cargo test --workspace --no-run
```
## Common Patterns
### Serde
Often only needs `derive`:
```toml
serde = { version = "1.0", default-features = false, features = ["derive", "std"] }
```
### Tokio
Identify which runtime features are actually used:
```toml
tokio = { version = "1.0", default-features = false, features = ["rt-multi-thread", "macros", "sync"] }
```
### Reqwest
Often doesn't need all TLS backends:
```toml
reqwest = { version = "0.11", default-features = false, features = ["rustls-tls", "json"] }
```
## Rollback
If changes cause issues:
```bash
git checkout quickwit/Cargo.toml
cargo check --workspace
```
## Tips
- Start with large crates that have many default features (tokio, reqwest, hyper)
- Use `cargo bloat --crates` to identify large dependencies
- Check `cargo tree -d` for duplicate dependencies that might indicate feature conflicts
- Some features are needed only for tests - consider using `[dev-dependencies]` features

description: Create a simple PR from staged changes with an auto-generated commit message
disable-model-invocation: true
---
# Simple PR
Follow these steps to create a simple PR from staged changes:
## Step 1: Check workspace state
Run: `git status`
Verify that all changes have been staged (no unstaged changes). If there are unstaged changes, abort and ask the user to stage their changes first with `git add`.
Also verify that we are on the `main` branch. If not, abort and ask the user to switch to main first.
## Step 2: Ensure main is up to date
Run: `git pull origin main`
This ensures we're working from the latest code.
## Step 3: Review staged changes
Run: `git diff --cached`
Review the staged changes to understand what the PR will contain.
## Step 4: Generate commit message
Based on the staged changes, generate a concise commit message (1-2 sentences) that describes the "why" rather than the "what".
Display the proposed commit message to the user and ask for confirmation before proceeding.
## Step 5: Create a new branch
Get the git username: `git config user.name | tr ' ' '-' | tr '[:upper:]' '[:lower:]'`
Create a short, descriptive branch name based on the changes (e.g., `fix-typo-in-readme`, `add-retry-logic`, `update-deps`).
Create and checkout the branch: `git checkout -b {username}/{short-descriptive-name}`
## Step 6: Commit changes
Commit with the message from step 3:
```
git commit -m "{commit-message}"
```
## Step 7: Push and open a PR
Push the branch and open a PR:
```
git push -u origin {branch-name}
gh pr create --title "{commit-message-title}" --body "{longer-description-if-needed}"
```
Report the PR URL to the user when complete.

// This benchmark compares different approaches for retrieving string values:
//
// 1. Fast Field Approach: retrieves string values via term_ords() and ord_to_str()
//
// 2. Doc Store Approach: retrieves string values via searcher.doc() and field extraction
//
// The benchmark includes various data distributions:
// - Dense Sequential: Sequential document IDs with dense data
// - Dense Random: Random document IDs with dense data
// - Sparse Sequential: Sequential document IDs with sparse data
// - Sparse Random: Random document IDs with sparse data

# sketches-ddsketch
This is a direct port of the [Golang](https://github.com/DataDog/sketches-go)
[DDSketch](https://arxiv.org/pdf/1908.10693.pdf) quantile sketch implementation
to Rust. DDSketch is a fully-mergeable quantile sketch with relative-error
guarantees and is extremely fast.
# DDSketch
* Sketch size automatically grows as needed, starting with 128 bins.
* Extremely fast sample insertion and sketch merges.
## Usage
```rust
use sketches_ddsketch::{Config, DDSketch};
let config = Config::defaults();
let mut sketch = DDSketch::new(c);
sketch.add(1.0);
sketch.add(1.0);
sketch.add(1.0);
// Get p=50%
let quantile = sketch.quantile(0.5).unwrap();
assert_eq!(quantile, Some(1.0));
```
## Performance
No performance tuning has been done with this implementation of the port, so we
would expect similar profiles to the original implementation.
Out of the box we see can achieve over 70M sample inserts/sec and 350K sketch
merges/sec. All tests run on a single core Intel i7 processor with 4.2Ghz max
clock.

//! This crate provides a direct port of the [Golang](https://github.com/DataDog/sketches-go)
//! [DDSketch](https://arxiv.org/pdf/1908.10693.pdf) implementation to Rust. All efforts
//! have been made to keep this as close to the original implementation as possible, with a few
//! tweaks to get closer to idiomatic Rust.
//!
//! # Usage
//!
//! Add multiple samples to a DDSketch and invoke the `quantile` method to pull any quantile from
//! 0.0* to *1.0*.
//!
//! ```rust
//! use sketches_ddsketch::{Config, DDSketch};
//!
//! let c = Config::defaults();
//! let mut d = DDSketch::new(c);
//!
//! d.add(1.0);
//! d.add(1.0);
//! d.add(1.0);
//!
//! let q = d.quantile(0.50).unwrap();
//!
//! assert!(q < Some(1.02));
//! assert!(q > Some(0.98));
//! ```
//!
//! Sketches can also be merged.
//!
//! ```rust
//! use sketches_ddsketch::{Config, DDSketch};
//!
//! let c = Config::defaults();
//! let mut d1 = DDSketch::new(c);
//! let mut d2 = DDSketch::new(c);

//! d1.add(1.0);
//! d2.add(2.0);
//! d2.add(2.0);
//!
//! d1.merge(&d2);
//!
//! assert_eq!(d1.count(), 3);
