getNodeAllocator

public NodeAllocator getNodeAllocator(Session session)

Specified by:

getNodeAllocator in interface NodeAllocatorService

acquire

public NodeAllocator.NodeLease acquire(NodeRequirements nodeRequirements,
 io.airlift.units.DataSize memoryRequirement,
 boolean speculative)

Description copied from interface: NodeAllocator

Requests acquisition of node. Obtained node can be obtained via NodeAllocator.NodeLease.getNode() method. The node may not be available immediately. Calling party needs to wait until future returned is done. It is obligatory for the calling party to release all the leases they obtained via NodeAllocator.NodeLease.release().

Specified by:

acquire in interface NodeAllocator

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface NodeAllocator

createPartitionMemoryEstimator

public PartitionMemoryEstimator createPartitionMemoryEstimator()

Specified by:

createPartitionMemoryEstimator in interface PartitionMemoryEstimatorFactory
