 <p>You can modify the TTL depending on how frequently the Hive metadata is updated.
If the Hive metadata is updated frequently, decrease the cache TTL value. If Hive metadata
is updated infrequently, increase the cache TTL value.</p>
 
-<p>For example, when you run a Drill query on a Hive table, Drill refreshes the cache
60 seconds after the read on the table. If the table is updated in Hive within that 60 second
window and you issue another query on the table, the query would return incorrect results
or an execution error due to a stale cache. In such a scenario where Hive metadata is changing
so quickly, you may want to reduce the cache TTL to 2 seconds so that Drill refreshes the
cache more frequently.  </p>
