eProsima DDS Record Documentation

eProsima

eProsima DDS Record is an end-user software application that efficiently saves DDS data published into a DDS environment in a MCAP format database. Thus, the exact playback of the recorded network events is possible as the data is linked to the timestamp at which the original data was published. At the moment, it is only possible to replay the data using external tools capable of interpreting the MCAP format, as the eProsima DDS Record does not provide a replay tool.

eProsima DDS Record is easily configurable and installed with a default setup, so that DDS topics, data types and entities are automatically discovered without the need to specify the types of data recorded. This is because the recording tool exploits the DynamicTypes functionality of eProsima Fast DDS, the C++ implementation of the DDS (Data Distribution Service) Specification defined by the Object Management Group (OMG).

Overview

eProsima DDS Record includes the following tools:

  • DDS Recorder tool. The main functionality of this tool is to save the data in a MCAP database. The database contains the records of the publication timestamp of the data, the serialized data, and the definition of the data serialization type and format. The output MCAP file can be read with any user tool compatible with MCAP file reading since it contains all the necessary information for reading and reproducing the data.

  • DDS Remote Controller tool. This application allows remote control of the recording tool. Thus, a user can have the recording tool on a device and from another device send commands to start, stop or pause data recording.
