ReporterProperties reporterProperties = new ReporterProperties()
.setBufferedMaxMessages(500)
.setPendingMaxMessages(10000)
.setMetrics("inmemory")
.setMetricsExporter("http")
.setParallelismPerBatch(5)
.setSenderExecutor(new ThreadPoolExecutor(200,
200, 0, TimeUnit.MILLISECONDS, new SynchronousQueue()));
BatchedJdbcTemplate template = new BatchedJdbcTemplate(reporterProperties);
template.setDataSource(dataSource);
Promise promise = template.update(...);
promise.done(success -> ...)
.fail(reject -> ...);吞吐量对比
