Hi [~anishek] ,

An example would be when Impala writes stats information to Partition objects 
and accesses it, as shown :  
 [Impala 
stats|https://github.com/apache/impala/blob/d48ffc2d45b2a9d4b9c730bba5677d3096311a25/fe/src/main/java/org/apache/impala/catalog/PartitionStatsUtil.java#L46]

But this information is not relevant as a Partition metadata for any other 
purpose. Also, these parameters have considerably large-size. On running some 
preliminary tests, we observe that there is a performance hit on increasing 
message size of HMS Notifications, so we can use this configuration to filter 
parameters like above mentioned.

 

Edited : Updated the link which was pointing to wrong one previously.
