Rendering `foxglove.Grid` is slower than `nav_msgs/OccupancyGrid`

3

**Description** Anecdotal evidence is that `foxglove.Grid` is slower to render than ROS `nav_msgs/OccupancyGrid`, at least when using protobuf encoding. - Do we have a way to benchmark this? - How...

Terminology: Markers vs Annotations

Foxglove alternative to ROS' [sensor_msgs/JointState](http://docs.ros.org/en/noetic/api/sensor_msgs/html/msg/JointState.html).

Data source extensions

Currently, extensions only support implementing custom panels. We want to add support for extensions to implement a custom data source (player).

Improve caching behavior for remote files (bag and mcap)

6

When playing the sample nuscenes data, we download the entire dataset multiple times over. We even re-download the entire dataset when I do things like delete a panel. We should...

Standardize default chunk size across official libraries

2

From @wkalt: > yeah, there is some variance. the libs are 1MB for python and go, 768kb for C++, and 10MB for swift > with the go CLI using 8MB...

We should prove that all implementations implement correct log_time playback

Performance test Foxglove Websocket

1

Questions came up around sending 4 channels of raw images @ 15hz, ~8mb per frame (~1 Gbps per channel). We should create a simple performance test to generate data using...

Support `--repeat-latched` in ROS 2 (transient local)
