Large Data Types (LDTs) allow individual record bins to contain collections of hundreds of thousands of objects. Developers can employ LDTs to manipulate large amounts of data quickly and efficiently, without being concerned with record or record bin size limitations.
Common functionality is provided by the abstract class AerospikeLDT. For each LDT type there is a matching concrete subclass:
- \Aerospike\LDT\LList - The Aerospike Large Ordered List class
The following LDT types have been permanently removed after being deprecated.
- \Aerospike\LDT\LSet - The Aerospike Large Set class
- \Aerospike\LDT\LMap - The Aerospike Large Map class
- \Aerospike\LDT\LStack - The Aerospike Large Stack class
Full documentation of LDTs is available at the Aerospike website.
