In addition to a log message, I would like to associate some metadata to the log: some JWT attributes (e.g. the sub), the session id and transaction id. The reason I want a session and/or transaction id is to be able to identify that a set of logs which were generated during for the same logical operation. For example, if a trigger invokes several other functions and each of those functions logs something, I would like to be able to identify that the logs are from the same logical operation.
