public sealed class BatchWritePolicy| BatchWritePolicy() | Default constructor. |
| BatchWritePolicy(BatchWritePolicy) | Copy constructor. |
| Clone | Creates a deep copy of this batch write policy. |
| commitLevel |
Desired consistency guarantee when committing a command on the server. The default
(COMMIT_ALL) indicates that the server should wait for master and all replica commits to
be successful before returning success to the client.
Default: CommitLevel.COMMIT_ALL |
| durableDelete |
If the command 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). |
| expiration |
Record expiration. Also known as ttl (time to live).
Seconds record will live before being removed by the server.
Expiration values:
Default: 0 |
| filterExp |
Optional expression filter. If filterExp exists and evaluates to false, the specific batch key
request is not performed and resultCode is set to
FILTERED_OUT.
If exists, this filter overrides the batch parent filter for the specific key in batch commands that allow a different policy per key. Otherwise, this filter is ignored. Default: null |
| generation |
Expected generation. Generation is the number of times a record has been modified
(including creation) on the server. This field is only relevant when generationPolicy
is not NONE.
Default: 0 |
| generationPolicy |
Qualify how to handle record deletes based on record generation. The default (NONE)
indicates that the generation is not used to restrict deletes.
Default: GenerationPolicy.NONE |
| OnLockingOnly |
Execute the write command only if the record is not already locked by this transaction.
If this field is true and the record is already locked by this transaction, the command
will throw an exception with the MRT_ALREADY_LOCKED
error code.
This field is useful for safely retrying non-idempotent writes as an alternative to simply aborting the transaction. This field is not applicable to record delete commands. Default: false. |
| recordExistsAction |
Qualify how to handle writes where the record already exists.
Default: RecordExistsAction.UPDATE |
| sendKey |
Send user defined key in addition to hash digest.
If true, the key will be stored with the record on the server.
Default: false (do not send the user defined key) |
