Description
Having the ability to trace database calls is very useful. Imagine the following example flow:
app---(sql query)-->sidecar--->DB
if app sends SQL queries with the trace headers as SQL comments, then the sidecar can emit client-side trace spans, recording the DB call durations. [The more industrious lot can parse DB query logs to extract trace headers and emit server side spans?]
if app doesn't send the trace headers as comments, the sidecar can still inject them (it will be a broken trace, but a trace nevertheless).
I am not sure if mongodb supports comments - the same can be done for mongo as well.
