Field Documentation

◆ commit_level

as_policy_commit_level as_policy_batch_write::commit_level

Specifies the number of replicas required to be committed successfully when writing before returning transaction succeeded.

Definition at line 1124 of file as_policy.h.

◆ durable_delete

bool as_policy_batch_write::durable_delete

If the transaction results in a record deletion, leave a tombstone for the record. This prevents deleted records from reappearing after node failures. Valid for Aerospike Server Enterprise Edition only.

Default: false (do not tombstone deleted records).

Definition at line 1157 of file as_policy.h.

◆ exists

as_policy_exists as_policy_batch_write::exists

Specifies the behavior for the existence of the record.

Definition at line 1134 of file as_policy.h.

◆ filter_exp

struct as_exp* as_policy_batch_write::filter_exp

Optional expression filter. If filter_exp exists and evaluates to false, the transaction is ignored. This can be used to eliminate a client/server roundtrip in some cases.

aerospike_destroy() automatically calls as_exp_destroy() on all global default policy filter expression instances. The user is responsible for calling as_exp_destroy() on filter expressions when setting temporary transaction policies.

Default: NULL

Definition at line 1113 of file as_policy.h.

◆ gen

as_policy_gen as_policy_batch_write::gen

Specifies the behavior for the generation value.

Definition at line 1129 of file as_policy.h.

◆ key

as_policy_key as_policy_batch_write::key

Specifies the behavior for the key.

Definition at line 1118 of file as_policy.h.

◆ ttl

uint32_t as_policy_batch_write::ttl

The default time-to-live (expiration) of the record in seconds. This field will only be used if "as_operations.ttl" is set to AS_RECORD_CLIENT_DEFAULT_TTL. The as_operations instance is passed in to batch write functions along with as_policy_batch_write.

There are also special values that can be set in the record ttl:

  • AS_RECORD_DEFAULT_TTL: Use the server default ttl from the namespace.
  • AS_RECORD_NO_EXPIRE_TTL: Do not expire the record.
  • AS_RECORD_NO_CHANGE_TTL: Keep the existing record ttl when the record is updated.
