Should we limit cross-thread segment count, just like the span limit?

[shichaoyuan]

The number of spans in the segment is limited in TracingContext, which does not exceed 800 by default.

This mechanism does not limit the number of cross-thread.

Should we limit cross-thread segment count, just like the span limit?

[wu-sheng]

Generally, we don't want to, because it could be a one-to-many batch task.
Why do you raise this? Any specific case?

[wu-sheng]

How are you possible to know the threshold to set?

[shichaoyuan]

This threshold may depend on the respective needs and scenarios, just like spanLimit in SpanLimitWatcher, which should also be an empirical value.

[wu-sheng]

I mean, from plugin dev perspective, how to determine this value?
For example, about which plugin, you are confident to set the value?

[shichaoyuan]

Plugin developers do not need to pay attention to this value, only end users may need to pay attention.

[wu-sheng]

How to pay attention.
Exposing configurations is not the way to resolve issues, the solution of how to set this value is.
