Easy Data Purge in Cassandra
Data purging is key to ensuring that your database servers always have enough free space to store the ever-incoming humongous business data. The operational/transactional database needs to be rid of old data that is no longer necessary as per your business rules.
Cassandra being one of the most popular databases, it does offer a really simplistic approach to support your data purge needs — that is, an expiration time for each of the records that go inside. The technique is known as TTL (time to live).
