What’s new in Cassandra 0.7: expiring columns
This post discusses the use of expiring columns in Apache Cassandra, a distributed database system. Expiring columns allow for automatic deletion of data after a specified time-to-live (TTL) period. The process is designed to be efficient and low overhead. To create an expiring column, users can specify a TTL when inserting the column. Once the TTL expires, the column will be deleted asynchronously during compaction. This feature helps manage rapidly growing datasets by automating data cleanup without requiring manual deletion jobs.
