Examples of org.voltdb.client.SyncCallback

org.voltdb.client.SyncCallback
A utility class that allows a client to queue a stored procedure invocation asynchronously and then poll or join on the response. Useful when invoking multiple stored procedures synchronously from a single thread. Queue each of the invocations asynchronously with a different SyncCallback and then call {@link #waitForResponse} on each of the SyncCallbacks to join on the responses.

            int f_d1 = i % 10; // 10 unique dim1s
            int f_d2 = i % 50; // 50 unique dim2s
            int f_d3 = i % 100; // 100 unique dim3s


            boolean done;
            SyncCallback cb = new SyncCallback();
            do {
                done = client.callProcedure(cb, "InsertF", pkey++, f_d1, f_d2, f_d3,
                                            2, (i * 10), (i % 2));
                if (!done) {
                    client.backpressureBarrier();
                }
            } while (!done);




            if (!async) {
                cb.waitForResponse();
                vt = cb.getResponse().getResults()[0];
                assertTrue(vt.getRowCount() == 1);
                // assertTrue(vt.asScalarLong() == 1);
            }
