Number of threads
editNumber of threads
editThe Apache Http Async Client starts by default one dispatcher thread, and a
number of worker threads used by the connection manager, as many as the number
of locally detected processors (depending on what
Runtime.getRuntime().availableProcessors() returns). The number of threads
can be modified as follows:
RestClientBuilder builder = RestClient.builder(
new HttpHost("localhost", 9200))
.setHttpClientConfigCallback(new HttpClientConfigCallback() {
@Override
public HttpAsyncClientBuilder customizeHttpClient(
HttpAsyncClientBuilder httpClientBuilder) {
return httpClientBuilder.setDefaultIOReactorConfig(
IOReactorConfig.custom()
.setIoThreadCount(1)
.build());
}
});
