![]() This adds quite a lot of OpenTracing decoration for database activity. Specifically it adds tracing at four different levels: * emit a span for each "interaction" - ie, the top level database function that we tend to call "transaction", but isn't really, because it can end up as multiple transactions. * emit a span while we hold a database connection open * emit a span for each database transaction - actual actual transaction. * emit a span for each database query. I'm aware this might be quite a lot of overhead, but even just running it on a local Synapse it looks really interesting, and I hope the overhead can be offset just by turning down the sampling frequency and finding other ways of tracing requests of interest (eg, the `force_tracing_for_users` setting). |
