Guozhang Wang updated KAFKA-3170: --------------------------------- Fix Version/s: 0.9.0.1 > Default value of fetch_min_bytes in new consumer is 1024 while doc says it is > 1 > ------------------------------------------------------------------------------- > > Key: KAFKA-3170 > URL: https://issues.apache.org/jira/browse/KAFKA-3170 > Project: Kafka > Issue Type: Bug > Components: consumer > Affects Versions: 0.9.0.0 > Reporter: Rajini Sivaram > Assignee: Rajini Sivaram > Fix For: 0.9.0.1 > > > FETCH_MIN_BYTES_DOC says: > {quote} > The minimum amount of data the server should return for a fetch request. If > insufficient data is available the request will wait for that much data to > accumulate before answering the request. The default setting of 1 byte means > that fetch requests are answered as soon as a single byte of data is > available or the fetch request times out waiting for data to arrive. Setting > this to something greater than 1 will cause the server to wait for larger > amounts of data to accumulate which can improve server throughput a bit at > the cost of some additional latency. > {quote} > But the default value is actually set to 1024. Either the doc or the value > needs to be changed. Perhaps 1 is a better default? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
