No root span created for a query

[zwcn]

Hi,

When I made a sql query (like select * from sql where id = 1), I got four traces (see screenshot). I expected that there was a single trace that represented the whole execution path for this query, not four separate traces each of which represented a phase of the execution path.

According to the source code https://github.com/src-d/go-mysql-server/blob/master/server/handler.go#L78-L90, a context ctx is created and is passed into Query. There is no root span created in between.

Is there a way to create a root span without changing the source code? Thanks!

There is no way to create a root span without changing the source code, but a root span should definitely be created for this.
