Don Bosco Durai commented on RANGER-2199:
-----------------------------------------

Ranger Admin portal only supports audit logs stored in Solr. It depends on Solr 
for listing and search capabilities. And Solr can store and index billions of 
records. It has good redundancy and scalability architecture.

Kafka is mostly a messaging service. It is good for store and retrieve use 
cases. It generally has a smaller retention period (usually 1 month) and it is 
not possible to do search or listing/pagination from Kafka.

Let me know if got your question incorrectly.
