---|---|---|
![]() | Exists(BatchPolicy, Key ) |
Check if multiple record keys exist in one batch call.
The returned boolean array is in positional order with the original key array order.
The policy can be used to specify timeouts and maximum concurrent threads.
(Inherited from AerospikeClient.)If a batch request to a node fails, the entire batch is cancelled. |
![]() | Exists(Policy, Key) |
Determine if a record key exists.
Return whether record exists or not.
The policy can be used to specify timeouts.
(Inherited from AerospikeClient.) |
![]() | Exists(BatchPolicy, ExistsArrayListener, Key ) |
Asynchronously check if multiple record keys exist in one batch call.
Schedule the array exists command with a channel selector and return.
Another thread will process the command and send the results to the listener in a single call.
The policy can be used to specify timeouts. If a batch request to a node fails, the entire batch is cancelled. |
![]() | Exists(BatchPolicy, ExistsSequenceListener, Key ) |
Asynchronously check if multiple record keys exist in one batch call.
Schedule the exists command with a channel selector and return.
Another thread will process the command and send the results to the listener in multiple unordered calls.
The policy can be used to specify timeouts. If a batch request to a node fails, responses from other nodes will continue to be processed. |
![]() | Exists(BatchPolicy, CancellationToken, Key ) |
Asynchronously check if multiple record keys exist in one batch call.
Create listener, call asynchronous array exists and return task monitor.
The policy can be used to specify timeouts. If a batch request to a node fails, the entire batch is cancelled. |
