Hi Hans, The two storages we use are Cassandra and Elastic search and they are on the same datacenter for now. The Programming Language we use is Java and OS would be Ubuntu or CentOS. We get messages in JSON format so we insert into Elastic Search directly and for Cassandra we transform JSON message into appropriate model so we could insert into a Cassandra table. The rate we currently get is about 100K/sec which is awesome but I am pretty sure this will go down once when we implement 2PC or transactional writes.
Thanks, kant
