org.elasticsearch.client.HeapBufferedAsyncResponseConsumer
All Implemented Interfaces:
Closeable, AutoCloseable, org.apache.http.concurrent.Cancellable, org.apache.http.nio.protocol.HttpAsyncResponseConsumer<org.apache.http.HttpResponse>
public class HeapBufferedAsyncResponseConsumer extends org.apache.http.nio.protocol.AbstractAsyncResponseConsumer<org.apache.http.HttpResponse>
Default implementation of HttpAsyncResponseConsumer. Buffers the whole response content in heap memory, meaning that the size of the buffer is equal to the content-length of the response. Limits the size of responses that can be read based on a configurable argument. Throws an exception in case the entity is longer than the configured buffer limit.
