Field Detail

generationPolicy

public GenerationPolicy generationPolicy

generation

public int generation

Expected generation. Generation is the number of times a record has been modified (including creation) on the server. If a write operation is creating a record, the expected generation would be 0.

expiration

public int expiration

Expiration values:

• -1: Never expire for Aerospike 2 server versions >= 2.7.2 and Aerospike 3 server versions >= 3.1.4. For older servers, -1 means a very long (max integer) expiration.
• 0: Default to namespace configuration variable "default-ttl" on the server.
• > 0: Actual expiration in seconds.
