0.18.0 - Ingestion speed and memory footprint

https://github.com/user-attachments/assets/95380a64-df05-4f85-b40a-0c6b8ec8d5cf

• 📖 Release blogpost: http://rerun.io/blog/column-chunks
• 🧳 Migration guide: http://rerun.io/docs/reference/migration/migration-0-18

✨ Overview & highlights

Rerun 0.18 introduces new column-oriented APIs and internal storage datastructures (Chunk & ChunkStore) that can both simplify logging code as well as improve ingestion speeds and memory overhead by a couple orders of magnitude in many cases (timeseries-heavy workloads in particular).

These improvements come in 3 broad categories:

• a new send family of APIs, available in all 3 SDKs (Python, C++, Rust),
• a new, configurable background compaction mechanism in the datastore,
• new CLI tools to filter, prune and compact RRD files.

Furthermore, we started cleaning up our data schema, leading to various changes in the way represent transforms & images.

New send APIs

Unlike the regular row-oriented log APIs, the new send APIs let you submit data in a columnar form, even if the data extends over multiple timestamps.

This can both greatly simplify logging code and drastically improve performance for some workloads, in particular timeseries, although we have already seen it used for other purposes!

API documentation:

• 🐍 Python send_columns docs
• 🌊 C++ send_columns docs
• 🦀 Rust send_columns docs

API usage examples:

<details> <summary>Python timeseries</summary>

Using log() (slow, memory inefficient):

rr.init("rerun_example_scalar", spawn=True)

for step in range(0, 64):
    rr.set_time_sequence("step", step)
    rr.log("scalar", rr.Scalar(math.sin(step / 10.0)))

Using send() (fast, memory efficient):

rr.init("rerun_example_send_columns", spawn=True)

rr.send_columns(
    "scalars",
    times=[rr.TimeSequenceColumn("step", np.arange(0, 64))],
    components=[rr.components.ScalarBatch(np.sin(times / 10.0))],
)

</details> <details> <summary>C++ timeseries</summary>

Using log() (slow, memory inefficient):

const auto rec = rerun::RecordingStream("rerun_example_scalar");
rec.spawn().exit_on_failure();

for (int step = 0; step < 64; ++step) {
    rec.set_time_sequence("step", step);
    rec.log("scalar", rerun::Scalar(std::sin(static_cast<double>(step) / 10.0)));
}

Using send() (fast, memory efficient):

const auto rec = rerun::RecordingStream("rerun_example_send_columns");
rec.spawn().exit_on_failure();

std::vector<double> scalar_data(64);
for (size_t i = 0; i < 64; ++i) {
    scalar_data[i] = sin(static_cast<double>(i) / 10.0);
}
std::vector<int64_t> times(64);
std::iota(times.begin(), times.end(), 0);

auto time_column = rerun::TimeColumn::from_sequence_points("step", std::move(times));
auto scalar_data_collection =
    rerun::Collection<rerun::components::Scalar>(std::move(scalar_data));

rec.send_columns("scalars", time_column, scalar_data_collection);

</details> <details> <summary>Rust timeseries</summary>

Using log() (slow, memory inefficient):

let rec = rerun::RecordingStreamBuilder::new("rerun_example_scalar").spawn()?;

for step in 0..64 {
    rec.set_time_sequence("step", step);
    rec.log("scalar", &rerun::Scalar::new((step as f64 / 10.0).sin()))?;
}

Using send() (fast, memory efficient):

let rec = rerun::RecordingStreamBuilder::new("rerun_example_send_columns").spawn()?;

let timeline_values = (0..64).collect::<Vec<_>>();
let scalar_data: Vec<f64> = timeline_values
    .iter()
    .map(|step| (*step as f64 / 10.0).sin())
    .collect();

let timeline_values = TimeColumn::new_sequence("step", timeline_values);
let scalar_data: Vec<Scalar> = scalar_data.into_iter().map(Into::into).collect();

rec.send_columns("scalars", [timeline_values], [&scalar_data as _])?;

</details>

Background compaction

The Rerun datastore now continuously compacts data as it comes in, in order find a sweet spot between ingestion speed, query performance and memory overhead.

This is very similar to, and has many parallels with, the micro-batching mechanism running on the SDK side.

You can read more about this in the dedicated documentation entry.

Post-processing of RRD files

To help improve efficiency for completed recordings, Rerun 0.18 introduces some new commands for working with rrd files.

Multiple files can be merged, whole entity paths can be dropped, and chunks can be compacted.

You can read more about it in the new CLI reference manual, but to give a sense of how it works the below example merges all recordings in a folder and runs chunk compaction using the max-rows and max-bytes settings:

rerun rrd compact --max-rows 4096 --max-bytes=1048576 /my/recordings/*.rrd > output.rrd

Overhauled 3D transforms & instancing

As part of improving our arrow schema and in preparation for reading data back in the SDK, we've split up transforms into several parts. This makes it much more performant to log large number of transforms as it allows updating only the parts you're interested in, e.g. logging a translation is now as lightweight as logging a single position.

There are now additionally InstancePoses3D which allow you to do two things:

• all 3D entities: apply a transform to the entity without affecting its children
• Mesh3D/Asset3D/Boxes3D/Ellipsoids3D: instantiate objects several times with different poses, known as "instancing"
  • Support for instancing of other archetypes is coming in the future!

All four tetrahedron meshes on this screen share the same vertices and are instanced using an InstancePoses3D archetype with 4 different translations

⚠️ Breaking changes

• .rrd files from older versions won't load correctly in Rerun 0.18
• mesh_material: Material has been renamed to albedo_factor: AlbedoFactor #6841
• Transform3D is no longer a single component but split into its constituent parts. From this follow various smaller API changes
• Python: NV12/YUY2 are now logged with Image
• ImageEncoded is deprecated and replaced with EncodedImage (JPEG, PNG, …) and Image (NV12, YUY2, …)
• DepthImage and SegmentationImage are no longer encoded as a tensors, and expects its shape in [width, height] order

0.17.0 - More Blueprint features and better notebooks - 2024-07-08

https://github.com/rerun-io/rerun/assets/49431240/1c75b816-7e3e-4882-9ee6-ba124c00d73c

📖 Release blogpost: https://rerun.io/blog/blueprint-overrides

🧳 Migration guide: http://rerun.io/docs/reference/migration/migration-0-17

✨ Overview & highlights

• 🟦 Blueprint component override & defaults, and visualizer override for all views
  • Component defaults: Configure default component value for an entire view, used when no values are logged to the data store (using rr.log()).
  • Component overrides: Specify a value to use regardless of the data-store & default values and use specified value instead. Can be set per view per entity.
  • Visualizer overrides: Specify a visualizer to use for a given entity in a given view. Previously only available for scalar data in timeseries views, now available for all view kinds.
  • All three are available from the (fully revamped) UI and the Python blueprint APIs.
  • Everything that was editable per entity in a view now uses component overrides (e.g. camera plane distance, transform axis lengths, etc.)
  • Tip: Tooltips for each component in the UI include a link to the docs now!
• 🕸️ Improved notebook & website embedding support
  • Now you can stream data from the notebook cell to the embedded viewer.
  • Much improved support for having multiple viewers on the same web page.
  • More configuration options have been added to control the visibility of the Menu bar, time controls, etc.
  • Note: Use pip install "rerun-sdk[notebook]" to include the better notebook support. This includes the new rerun-notebook package, which is used internally by [rerun-sdk].
• 🧑‍🏫 New Examples
  • Paddle OCR
  • Vista driving world model
  • Stereo Vision SLAM
  • Neural field notebook
• 🛠️ Improved the logging API with many new and updated archetypes and components (see migration guide)
• 🖼️ TensorView is now fully configurable from blueprint code
• 🎛️ Revamped selection panel UI
• 🚚 Much work is being done under-the-hood to migrate our data-store to "chunks" (aka units of batched data). More on this in the next release!
  • SDKs are already using chunks to transport data to the viewer, performance characteristics may have changed but should be largely the same for the moment.

⚠️ Breaking changes

• HalfSizes2D has been renamed to HalfSize2D
• HalfSizes3D has been renamed to HalfSize3D
