## What changed? <!-- Describe what has changed in this PR --> - Use caller type to determine history requests priority ## Why? <!-- Tell your future self why have you made these changes --> - Right now the priority feature is only used for prioritizing operator requests, but doesn't help with background requests increase case which can cause user requests to be throttled as well. ## How did you test it? <!-- How have you verified this change? Tested locally? Added a unit test? Checked in staging env? --> ## Potential risks <!-- Assuming the worst case, what can be broken when deploying this change to production? --> ## Documentation <!-- Have you made sure this change doesn't falsify anything currently stated in `docs/`? If significant new behavior is added, have you described that in `docs/`? --> ## Is hotfix candidate? <!-- Is this PR a hotfix candidate or does it require a notification to be sent to the broader community? (Yes/No) -->
