Constructor Detail

StreamingHttpResponseAccumulator

public StreamingHttpResponseAccumulator(org.apache.druid.query.context.ResponseContext responseContext,
                                        QueryResultPusher.ResultsWriter resultsWriter)

Method Detail

getNumBytesSent

public long getNumBytesSent()

isInitialized

public boolean isInitialized()

initialize

public void initialize()

Initializes the response. This is done lazily so that we can put various metadata that we only get once we have some of the response stream into the result.

It is okay for this to be called multiple times.
