  - close
```
void close()
```
    Close all client connections to database server nodes.
    If event loops are defined, the client will send a cluster close signal to these event loops. The client instance does not initiate shutdown until the pending async commands complete. The close() method, however, will return before shutdown completes if close() is called from an event loop thread. This is done in order to prevent deadlock.
    This close() method will wait for shutdown if the current thread is not an event loop thread. It's recommended to call close() from a non event loop thread for this reason.

            BatchPolicy batchPolicy,
            BatchDeletePolicy deletePolicy,
            Key[] keys)
     throws AerospikeException
```
    Asynchronously delete records for specified keys. This method registers the command with an event loop and returns. The event loop thread will process the command and send the results to the listener.
    Each record result is returned in separate onRecord() calls. If a key is not found, the corresponding result BatchRecord.resultCode will be ResultCode.KEY_NOT_FOUND_ERROR.
    Requires server version 6.0+
    
    Parameters:
    
    eventLoop - event loop that will process the command. If NULL, the event loop will be chosen by round-robin.
    
    listener - where to send results
    
    batchPolicy - batch configuration parameters, pass in null for defaults
    
    deletePolicy - delete configuration parameters, pass in null for defaults

```
void truncate(InfoPolicy policy,

              Calendar beforeLastUpdate)
       throws AerospikeException
```
    Remove records in specified namespace/set efficiently. This method is many orders of magnitude faster than deleting records one at a time.
    See https://www.aerospike.com/docs/reference/info#truncate
    This asynchronous server call may return before the truncation is complete. The user can still write new records after the server call returns because new records will have last update times greater than the truncate cutoff (set at the time of truncate call).
    
    Parameters:
    
    policy - info command configuration parameters, pass in null for defaults
    
    ns - required namespace
    
    set - optional set name. Pass in null to delete all sets in namespace.
    
    beforeLastUpdate - optional delete records before record last update time. If specified, value must be before the current time. Pass in null to delete all records in namespace/set.
    
    Throws:
    
    AerospikeException - if truncate fails
  - touch

    Asynchronously read multiple record header data for specified keys in one batch call. This method registers the command with an event loop and returns. The event loop thread will process the command and send the results to the listener.
    Each record result is returned in separate onRecord() calls. If a key is not found, the record will be null.
    
    Parameters:
    
    eventLoop - event loop that will process the command. If NULL, the event loop will be chosen by round-robin.
    
    listener - where to send results
    
    policy - batch configuration parameters, pass in null for defaults

    Parameters:
    
    policy - write configuration parameters, pass in null for defaults
    
    key - unique record identifier

    udf file = <server udf dir>/<package name>.lua
    Requires server version 6.0+
    
    Parameters:
    
    eventLoop - event loop that will process the command. If NULL, the event loop will be chosen by round-robin.

void query(QueryPolicy policy,
           Statement statement,
           QueryListener listener)
    throws AerospikeException
```
    Execute query on all server nodes and return records via the listener. This method will block until the query is complete. Listener callbacks are made within the scope of this call.
    If QueryPolicy.maxConcurrentNodes is not 1, the supplied listener must handle shared data in a thread-safe manner, because the listener will be called by multiple query threads (one thread per node) in parallel.
    Requires server version 6.0+ if using a secondary index query.
    
    Parameters:
    
    policy - query configuration parameters, pass in null for defaults
    
    statement - query definition.
    
    listener - where to send results

    throws AerospikeException
```
    Execute query for specified partitions and return records via the listener. This method will block until the query is complete. Listener callbacks are made within the scope of this call.
    If QueryPolicy.maxConcurrentNodes is not 1, the supplied listener must handle shared data in a thread-safe manner, because the listener will be called by multiple query threads (one thread per node) in parallel.
    The completion status of all partitions is stored in the partitionFilter when the query terminates. This partitionFilter can then be used to resume an incomplete query at a later time. This is the preferred method for query terminate/resume functionality.
    Requires server version 6.0+ if using a secondary index query.
    
    Parameters:
    
    policy - query configuration parameters, pass in null for defaults
    
    statement - query definition.
    
    partitionFilter - data partition filter. Set to PartitionFilter.all() for all partitions.
