SUMMARY
When using the improved SQLLab persistence mode, an ID value is initially generated to manage the tab in localStorage when the tab is created. After syncing with the server, this ID is immediately replaced with the server’s tabViewId, and subsequent data synchronization uses this new ID. Since this ID serves as the key for the SQLLab tab, updating the value causes React to treat it as a new tab, resulting in the component being re-rendered.
To solve this issue, we now preserve the ID for the duration of the session and additionally store the tabViewId. We have modified the system to use tabViewId specifically for data synchronization, which resolves the problem of tab flushing.
