Optimized for robotics – record, playback, carve, or rewrite small or large data efficiently & reliably. A fast & scalable data logging system for the cloud.
Capabilities
- The Log writer supports high data rates (3GB+/second)
- Onboard, the Log Writer is “power safe”.
- The logger supports native compression. Transparantely compresses with LZ4 or Zstd if desired.
Format
Ark Logs are organized on disk for efficient I/O and data transfers. They ocnsisit of two major dimensions: split files break logs up into multiple files, and columns organize specific channels into those split files. These allow you to efficiently read (and download) only the data you care about for your test (along with supporting fast seeking and subsets of data).
Tools
Ark Logs come with built in tooling:
- Quick (sub-millisecond) export of log sub-sections
- Dump logs to JSON or CSV for ingestion by other tools
- Logs can be “amended”, that is, can have data efficiently replaced or augemented without rewriting the entire log
