Apache Cassandra - Tutorial 10 - CQL - Timestamps, TTLs, Collections and Secondary Indexs

In our third video on Cassandra Query Language we will look at some slightly more advanced features of the language.
We will look at timestamps in Cassandra and how we can add and access these when we are writing and reading data from Cassandra.
TTL's or Time To Lives are an excellent feature that allows us to expire part of our data after a certain time period. In this video we will see how these are used through CQL.
We will look at how Cassandra stores a collection (similar to an array or list) of items in a single database column.
Finally we will look at secondary indexs in CQL. While there use is often I'll advised it is often necessary to use them to access data by something that is not part of our partition key.
