Problem Statement
How can you implement polling and automatic refetching in RTK Query?
Explanation
You can enable polling by passing a pollingInterval option in milliseconds to your query hook, which will automatically refetch the data at that interval while the component is mounted. RTK Query also provides refetchOnMountOrArgChange to control whether queries refetch when components remount or arguments change, refetchOnFocus to refetch when the window regains focus, and refetchOnReconnect to refetch when network reconnects after being offline. You can also manually trigger refetches using the refetch function returned by the hook, and combine these options to create sophisticated data synchronization strategies that keep your UI fresh without manual intervention.
