We are currently looking at a distributed database option and so far Cassandra ticks all the boxes. However, I still have some questions.
Is there any need for archiving of Cassandra and what backup options are available? As it is a no-data-loss system I’m guessing archiving is not exactly relevant.
Is there any concept of Listeners such that when data is added to Cassandra we can fire off another process to do something with that data? E.g. create a copy in a secondary database for Business Intelligence reports? Send the data to an LDAP server?
