Automatic Refresh of Tables on Impala Clusters

The property enable_insert_events is used in CDP to refresh the tables or partitions automatically on other Impala clusters when Impala inserts into a table.

If Impala inserts into a table it refreshes the underlying table or partition. When this configuration enable_insert_events is set to True (default) Impala generates INSERT event types which when received by other Impala clusters automatically refreshes the tables or partitions.
