AerospikeClient (aerospike-client 7.1.0 API)

java.lang.Object
- com.aerospike.client.AerospikeClient

All Implemented Interfaces:

IAerospikeClient, Closeable, AutoCloseable
```
public class AerospikeClient
extends Object
implements IAerospikeClient, Closeable
```
Instantiate an AerospikeClient object to access an Aerospike database cluster and perform database operations.
This client is thread-safe. One client instance should be used per cluster. Multiple threads should share this cluster instance.
Your application uses this class API to perform database operations such as writing and reading records, and selecting sets of records. Write operations include specialized functionality such as append/prepend and arithmetic addition.

public AerospikeClient(String hostname,
                       int port)
                throws AerospikeException
```
    Initialize Aerospike client. If the host connection succeeds, the client will:
    - Add host to the cluster map
    - Request host's list of other nodes in cluster
    - Add these nodes to cluster map
    
    If the connection succeeds, the client is ready to process database requests. If the connection fails, the cluster will remain in a disconnected state until the server is activated.
    
    Parameters:
    
    hostname - host name
    
    port - host port
    
    Throws:
    
    AerospikeException - if host connection fails
  - AerospikeClient
```
public AerospikeClient(ClientPolicy policy,
                       String hostname,
                       int port)
                throws AerospikeException
```
    Initialize Aerospike client. The client policy is used to set defaults and size internal data structures. If the host connection succeeds, the client will:
    - Add host to the cluster map
    - Request host's list of other nodes in cluster
    - Add these nodes to cluster map
    
    If the connection succeeds, the client is ready to process database requests. If the connection fails and the policy's failOnInvalidHosts is true, a connection exception will be thrown. Otherwise, the cluster will remain in a disconnected state until the server is activated.
    
    Parameters:
    
    policy - client configuration parameters, pass in null for defaults
    
    hostname - host name
    
    port - host port
    
    Throws:
    
    AerospikeException - if host connection fails
  - AerospikeClient
```
public AerospikeClient(ClientPolicy policy,
                       Host... hosts)
                throws AerospikeException
```
    Initialize Aerospike client with suitable hosts to seed the cluster map. The client policy is used to set defaults and size internal data structures. For the first host connection that succeeds, the client will:
    - Add host to the cluster map
    - Request host's list of other nodes in cluster
    - Add these nodes to cluster map
    
    In most cases, only one host is necessary to seed the cluster. The remaining hosts are added as future seeds in case of a complete network failure.
    If one connection succeeds, the client is ready to process database requests. If all connections fail and the policy's failIfNotConnected is true, a connection exception will be thrown. Otherwise, the cluster will remain in a disconnected state until the server is activated.
    
    Parameters:
    
    policy - client configuration parameters, pass in null for defaults
    
    hosts - array of potential hosts to seed the cluster
    
    Throws:
    
    AerospikeException - if all host connections fail

  - close
```
public 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.
    
    Specified by:
    
    close in interface IAerospikeClient
    
    Specified by:
    
    close in interface Closeable

```
    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).
    
    Specified by:

    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.

```
    Execute query on all server nodes and return record iterator. The query executor puts records on a queue in separate threads. The calling thread concurrently pops records off the queue through the record iterator.
    This method is not recommended for paginated queries when the user does not iterate through all records in the RecordSet. In this case, there is a lag between when the client marks the last record retrieved from the server and when the record is retrieved from the RecordSet. For this case, use query(QueryPolicy, Statement, QueryListener) which uses a listener callback (without a buffer) instead of a RecordSet.
    
    Specified by:
    
    query in interface IAerospikeClient
    
    Parameters:
    
    policy - query configuration parameters, pass in null for defaults
    
    statement - query definition
    
    Returns:
    
    record iterator

    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

                 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.
    
    Specified by:
    
    query in interface IAerospikeClient
    
    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.

    Execute query, apply statement's aggregation function, and return result iterator. The query executor puts results on a queue in separate threads. The calling thread concurrently pops results off the queue through the result iterator.
