mongo_msg_db

A simple MongoDB database for flat collections of ROS messages.

Usage

Once the database node is running, it provides services for adding messages to a MongoDB database, using the default MongoDB instance. The messages are saved and retrieved in JSON format, which is convenient for web purposes. We recommend using rospy_message_converter to do the conversion between ROS messages and JSON.

Services

See the service files for the full definitions.

• mongo_msg_db/delete: delete a message from a collection by ID
• mongo_msg_db/find: get a single message from a collection by ID
• mongo_msg_db/insert: insert a message to a collection and get its ID
• mongo_msg_db/list: get all messages from a collection
• mongo_msg_db/update: replace a message in a collection
