The SDK makes our app very slow over time on devices that block Segment

Some of our users (especially on Android) have reported that their app becomes very slow the more they use it.

After investigation, we realized that these members blocked tracking on their device (for example with pihole), leading to Segment being blocked. In this case, Segment SDK would keep persisting more and more events over time, leading to a situation where every tracked events caused the app to try to store thousands of events, making the app super slow.

We've addressed it by providing our own custom persistor that drops excessive number of events, but we should not have had to do that.

• analytics-react-native version: 2.20.2
• Integrations versions (if used): analytics-react-native-plugin-amplitude-session
• React Native version: 0.74.5
• iOS or Android or both? Android mostly, but it probably could happen to iOS too

Steps to reproduce

• Make sure events cannot be uploaded to Segment
• Track a lot of events
• Notice that the SDK will accumulate a lot of events and will try to persist them all every time a new event is tracked

Expected behavior

Some kind of sane defaults, where excessive events are dropped if they cannot be uploaded

Hi @simontreny thanks for reaching out- we'll prioritize this over the coming sprints
