SUMMARY
QueryAutoRefresh polls running query's status every 2 seconds. if query is running good, it calls
setUserOffline
(for every 2 seconds). Because Sql Lab uses redux-localStorage to sync redux state to localStorage, any time an action is dispatched in redux it will trigger localStorage update (even without any change), which is very unnecessary when there is no real state change.BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF
Before: i used redux chrome extension to show redux state update:
TEST PLAN
CI and manual check.
