Examples with QueryPolicy com.aerospike.client.policy.QueryPolicy used on opensource projects

Example 1 with QueryPolicy

use of com.aerospike.client.policy.QueryPolicy in project aerospike-client-java by aerospike.

the class AsyncClient method query.

// -------------------------------------------------------
// Query Operations
// -------------------------------------------------------
/**
 * Asynchronously execute query on all server nodes.  The query policy's
 * <code>maxConcurrentNodes</code> dictate how many nodes can be queried in parallel.
 * The default is to query all nodes in parallel.
 * <p>
 * This method schedules the node's query commands with channel selectors and returns.
 * Selector threads will process the commands and send the results to the listener.
 *
 * @param policy				query configuration parameters, pass in null for defaults
 * @param listener				where to send results
 * @param statement				database query command parameters
 * @throws AerospikeException	if query fails
