There is no info provided in atlas document on how to scale it.
Apache atlas is connected to cassandra or hbase in the backend which can scale out ,but I dont know how apache atlas engine ( rest web-service and request processor ) can scale out.
I can install multiple instances of it on different machine and have load balancer in front of it to fan out the request. But would this model help ? Does it do any kind of locking and do db transaction, so that this model would not work.
Does someone know how apache atlas scales out ?
Thanks.
Please refer to this page. http://atlas.apache.org/#/HighAvailability
Atlas does not support actual horizontal scale-out. All the requests are handled by the 'Active instance'. the 'Passive instances' just forward all the requests to the 'Active instance'.
