What is Groonga?

Groonga is putting a full-text search engine into WebAssembly and the browser.

Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.

What is Mapnik?

Mapnik 4.3.2 is a performance release from one contributor, with line dash fixes.

Mapnik ships small point releases with a growing set of outside contributors. 4.3.2 on September 23 is mostly one contributor's work: more performance changes, cached rasterized SVG polygon patterns, a GeoJSON fix and line dash offsets honored in both the AGG and Cairo renderers. A marker-dimension fix was merged, reverted and merged again in a corrected form, the same pattern as the font fix in 4.3.1.

5.0

Groonga is putting a full-text search engine into WebAssembly and the browser.

◆ Current state

Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.

◆ Where it's heading

The WebAssembly work is moving piece by piece from the core command to options and plugins, which points toward a usable in-browser search engine. Every WASI item is still marked experimental and not stable.

◆ Prediction

Expect more WASI coverage in the next 16.1.x releases, with the experimental label likely to stay for now.

0.0

Mapnik 4.3.2 is a performance release from one contributor, with line dash fixes.

◆ Current state

Mapnik ships small point releases with a growing set of outside contributors. 4.3.2 on September 23 is mostly one contributor's work: more performance changes, cached rasterized SVG polygon patterns, a GeoJSON fix and line dash offsets honored in both the AGG and Cairo renderers. A marker-dimension fix was merged, reverted and merged again in a corrected form, the same pattern as the font fix in 4.3.1.

◆ Where it's heading

Recent releases have turned from new data sources, such as remote PMTiles in 4.1.3, toward render speed and correctness. CI now runs on pull requests and forks, which makes outside contributions easier to land.

◆ Prediction

Expect another 4.3.x point release with further performance work; a 4.4 feature line is not visible in the entries.
