-------------------------------------
Summary: 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
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.

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?
