Understand the date and time data types available in Cassandra.
- [Instructor] Collections are used to store…multiple atomic values in a single column.…Now Cassandra can store up to 64000 items in a collection,…but it's the best practice to keep the collection small.…Cassandra reads all the contents of a collection…so long collections require more time to read.…Now there are 3 types of collections:…lists, sets, and maps.…Lists are used when the order of items matter…or when you might need to store…the same value multiple times.…
So, for example, here we have a list of host names,…AppServer1, AppServer2, LoadBalancer7, and LoadBalancer8.…Sets are like this, except…that there is no order to the items,…and each item can be stored only once.…Sets are more efficient to use than lists.…It's recommended to you sets instead of lists when possible.…So, for example, here is a set with the same host names…that we saw in the list example,…AppServer2, LoadBalancer8, LoadBalancer7, and AppServer1.…
Let's assume for our application that order doesn't matter,…since there are no duplicates,…
