Methods

getExpectedDuration()

QueryDuration represents the expected duration for a query operation in the Aerospike database.

public getExpectedDuration() : QueryDuration

It provides options for specifying whether a query is expected to return a large number of records per node (Long), a small number of records per node (Short), or a long query with relaxed read consistency for AP namespaces (LongRelaxAP). These options influence how the server optimizes query execution to meet the expected duration requirements.

Return values
QueryDuration

getMaxConcurrentNodes()

*************************************************************************** MultiPolicy Attrs *************************************************************************** Maximum number of concurrent requests to server nodes at any point in time.

public getMaxConcurrentNodes() : int

If there are 16 nodes in the cluster and maxConcurrentNodes is 8, then queries will be made to 8 nodes in parallel. When a query completes, a new query will be issued until all 16 nodes have been queried. Default (0) is to issue requests to all server nodes in parallel. 1 will to issue requests to server nodes one by one avoiding parallel queries.

Return values
int

getMaxRetries()

*************************************************************************** ReadPolicy Attrs ***************************************************************************

public getMaxRetries() : int
Return values
int

getRecordQueueSize()

Number of records to place in queue before blocking.

public getRecordQueueSize() : int

Records received from multiple server nodes will be placed in a queue. A separate goroutine consumes these records in parallel. If the queue is full, the producer goroutines will block until records are consumed.

Return values
int

setExitFastOnExhaustedConnectionPool()

public setExitFastOnExhaustedConnectionPool(bool $exit_fast_on_exhausted_connection_pool) : mixed
Parameters

setFilterExpression()

public setFilterExpression(mixed $filter_expression) : mixed
Parameters
$filter_expression : mixed

setMaxConcurrentNodes()

public setMaxConcurrentNodes(int $max_concurrent_nodes) : mixed
Parameters
$max_concurrent_nodes : int
