Sorry, I copy-and-pasted the wrong variable name. I meant to copy and paste streaming_socket_timeout_in_ms. So my question should be:
streaming_socket_timeout_in_ms is the timeout per operation on the streaming socket. The docs recommend not to set it too low (because a timeout causes streaming to restart from the beginning). But the default 0 never times out. What's a reasonable value? # Enable socket timeout for streaming operation. # When a timeout occurs during streaming, streaming is retried from the start # of the current file. This _can_ involve re-streaming an important amount of # data, so you should avoid setting the value too low. # Default value is 0, which never timeout streams. # streaming_socket_timeout_in_ms: 0 My second question is: Does it stream an entire SSTable in one operation? I doubt it. How large is the object it streams in one operation? I'm tempted to put the timeout at 30 seconds or 1 minute. Is that too low?. The entire file (SSTable) is large – several hundred megabytes. Is the timeout for streaming the entire file? Or only a block of it?

What's a reasonable value? no, it is not a timeout, it states how fast sstables are streamed Does it stream an entire SSTable in one operation? I doubt it.

Is that too low? unsure what you meat by 'operation' here, but it is one tcp connection, streaming the whole file (if thats what we want) /Marcus
