Represents a cached table entry with a unique refresher for each query. This design ensures that even if two queries are identical in structure, their refreshers can maintain independent states. The refreshFunction is responsible for refreshing the pre-signed URLs for the table, while the RefresherWrapper allows additional customization or state management during the refresh process. This is necessary because the server may require specific states in the refresher function to refresh the pre-signed URLs. The refresh results can be shared across the same query for the same table.

Example: Query 1: SELECT * FROM table WHERE col1 = 'value1' Query 2: SELECT * FROM table WHERE col1 = 'value1' Both queries can share the same cache entry for the table, but their refreshers maintain independent states to handle server-specific requirements for refreshing pre-signed URLs. When Query 2 ends, and Query 1 keeps running, we need to maintain Query 1's refresher state to ensure it continues to refresh the pre-signed URLs as needed.
