About:
MCAP provides a serialization-agnostic container file format designed for efficient storage and playback of pub/sub messages. It combines message indexes, schemas, and data into a single, self-contained file, enabling robust data logging and exchange across diverse systems.
|
Key Features:
- Serialization format agnostic
- Self-contained with indexes and schemas
- Optimized for append-only I/O
- Supports data recovery from truncated files
|
Use Cases:
- Long-term storage of robotics sensor data
- Offline analysis of message logs
- Data exchange between different pub/sub systems
|
Alternatives:
-
ROS Bag
– ROS-specific, less portable for non-ROS ecosystems
-
SQLite
– General-purpose database, not optimized for message streams
