Package io.airlift.concurrent

Class 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
