}

Example 4 with InternalCompletableFuture

use of com.hazelcast.spi.impl.InternalCompletableFuture in project hazelcast by hazelcast.

the class InvocationUtil method invokeOnStableClusterSerial.

/**
 * Invoke operation on all cluster members.
 *
 * The invocation is serial: It iterates over all members starting from the oldest member to the youngest one.
 * If there is a cluster membership change while invoking then it will restart invocations on all members. This
 * implies the operation should be idempotent.
 *
 * If there is an exception - other than {@link com.hazelcast.core.MemberLeftException} or
 * {@link com.hazelcast.spi.exception.TargetNotMemberException} while invoking then the iteration
 * is interrupted and the exception is propagated to the caller.

    return new ChainingFuture(invocationIterator, memberIterator);
}

Example 5 with InternalCompletableFuture

use of com.hazelcast.spi.impl.InternalCompletableFuture in project hazelcast by hazelcast.

the class MapProxySupport method putAllInternal.

/**
 * This method will group all entries per partition and send one operation
 * per member. If there are e.g. five keys for a single member, even if
 * they are from different partitions, there will only be a single remote
 * invocation instead of five.
 * <p>
 * There is also an optional support for batching to send smaller packages.
 * Takes care about {@code null} checks for keys and values.
 *
 * @param future iff not-null, execute asynchronously by completing this future.
 *               Batching is not supported in async mode
