Feature Request: Remote Config Option for Session Replay Sample Rate in Mobile SDKs

[Prithvirajkumar]

Problem Statement

Customers are testing out Session Replay for their mobile applications.
During testing and potential scaling, they require the option to dynamically adjust the Session Replay sample rate without requiring an app release.

In scenarios where developers need to fine-tune the sample rate based on app performance, user behavior, or infrastructure considerations, rolling out an app update to modify the sample rate is both time-consuming and inefficient.

The proposed solution is for Sentry to provide support for remote configuration of the Session Replay sample rate in the Mobile SDKs.
This feature would allow developers to change the sample rate dynamically via a remote request after SDK initialization.

Remote configuration would provide:

• Greater flexibility in managing Session Replay settings.
• Improved ability to scale and test effectively during rollout phases.
• Reduced operational friction for engineering teams managing frequent changes to sample rates.

The ability to configure the SDK remotely makes a lot of sense, specially on mobile environments.
Thanks for raising.

We have not planned to implement this yet though.
The work around now is to use another service, to get the config before initializing Sentry.
Unfortunately that means that if fetching the config fails, Sentry won't report on that since it happens before Sentry inits/
