Pre-release

This release is a pre-release and may not be stable for production use.

Shadebags

Shade is an extremely fast & highly queryable bag format built for big data robotics. Compress & query ROS or custom data.

Features

  • Highly modular, adding new compression algorithms and bag types is easy
  • Multicore compression - compress extremely fast (we experienced a 5x speed boost over rosbag compress)
  • Better compression ratios. By matching the algorithm to the datatype, much better compression ratios are achieved

Usage

Just pip install shadebags and shadebags compress ./example.bag ROS1

This will give a new file ./example.shade. To recover the original bag just run

shadebags decompress ./example.shade.
