Collection types provide an improved way of handling tasks, such as building multiple email address capability into tables.
- The maximum size of an item in a collection is 64K.
- Keep collections small to prevent delays during querying
because Cassandra reads a collection in its entirety. The collection is not paged
As discussed earlier, collections are designed to store only a small amount of data.
- Never insert more than 64K items in a collection.
If you insert more than 64K items into a collection, only 64K of them will be queryable, resulting in data loss.
You can expire each element of a collection by setting an individual time-to-live (TTL) property.
