smiletrl opened a new issue #669:
URL: https://github.com/apache/rocketmq-client-go/issues/669
**FEATURE REQUEST**
1. Please describe the feature you are requesting.
I want to pass context into transaction listener `ExecuteLocalTransaction`.
So it looks like `ExecuteLocalTransaction(context.Context, *Message)
LocalTransactionState`. This passed context comes from
`SendMessageInTransaction(ctx context.Context, msg *primitive.Message)
(*primitive.TransactionSendResult, error)`.
Here're three scenarios for this context usage.
- I want to add jaeger tracing support for everything happening inside
`ExecuteLocalTransaction`. The jaeger tracing needs to use a parent context,
so jaeger can track operations in a tracing life cycle. For example, here's an
usage example for context inside [mongo
operation](https://github.com/smiletrl/micro_ecommerce/blob/master/pkg/mongodb/mongodb.go#L59).
If mongodb has been invoked inside `ExecuteLocalTransaction`, then we can
track this mongodb operation through the passed context.
- I want `ExecuteLocalTransaction` to cancel early when the passed context
has canceled. For example, if there's one long time running sql query inside
`ExecuteLocalTransaction`, then it should cancel the query if the outer context
has canceled.
- I want to pass additional values into `ExecuteLocalTransaction`, like
[what this issue needs](https://github.com/apache/rocketmq-client-go/issues/668)
2. Provide any additional detail on your proposed use case for this feature.

2. Indicate the importance of this issue to you (blocker, must-have,
should-have, nice-to-have). Are you currently using any workarounds to address
this issue?
For scenario three, one workaround is to pass values through the message.
For scenario 1 and 2, there're no workarounds. It's a blocker for our
development process. We must need be able to track time consuming tasks inside
`ExecuteLocalTransaction` through the whole request cycle, and we want to be
able to cancel long time running tasks inside `ExecuteLocalTransaction` when we
want.
4. If there are some sub-tasks using -[] for each subtask and create a
corresponding issue to map to the sub task:
no nope.
