----------------------------------------
Summary: Streaming sessions longer than 3 minutes fail with timeout
Key: CASSANDRA-17510
URL: https://issues.apache.org/jira/browse/CASSANDRA-17510
Project: Cassandra
Issue Type: Bug
Reporter: Jon Meredith
Streaming sessions that take longer than 3 minutes will fail with an
InputTimeoutException on the streaming control channel connection.
CASSANDRA-16927 refactored the streaming code as part of CEP-10 to clean up
some abstractions. As part of those changes the StreamDeserializingTask
(formerly StreamingInboundHandler) had a check removed that ensured data was
present before reading from the AsyncStreamingInputPlus used by
NettyStreamingChannel to pass incoming bytes to be deserialized off the main
Netty event loop threads. When {{reBuffer}ing from the input,
AsyncStreamingInputPlus times out if no data is received in three minutes.
It is perfectly valid for no messages to be received over the control
connection for longer than three minutes - pre CASSANDRA-16927 just doesn’t do
the read until data is present, so it doesn’t hit the timeout. A possible
solution is to replace throwing the InputTimeoutException with a check that the
channel is still open and retry.
Note this is unrelated to the streaming protocol KeepAlive removal - that had a
default timeout of five minutes so would not have been effective anyway.
