Class BoundedExecutor

java.lang.Object

io.airlift.concurrent.BoundedExecutor

All Implemented Interfaces:

Executor

@ThreadSafe
public class BoundedExecutor
extends Object
implements Executor

Guarantees that no more than maxThreads will be used to execute tasks submitted through execute().

There are a few interesting properties:

• Multiple BoundedExecutors over a single coreExecutor will have fair sharing of the coreExecutor threads proportional to their relative maxThread counts, but can use less if not as active.
• Tasks submitted to a BoundedExecutor is guaranteed to have those tasks handed to threads in that order.
• Will not encounter starvation
