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? Some of our rebuilds hang for many hours and we figure we need a timeout. Thanks, Don |

unsure what you meat by 'operation' here, but it is one tcp connection, streaming the whole file (if thats what we want) /Marcus |
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:

The entire file (SSTable) is large – several hundred megabytes. Is the timeout for streaming the entire file? Or only a block of it? Don From: Marcus Eriksson [mailto:[hidden email]]

Hi guys, this (old) thread has no answers. @Donald, did you find out answer to your second question ? (first one depends on the second imho) @all, Any pointer or extra info would be great. Alain 2014-10-22 18:03 GMT+02:00 Donald Smith <[hidden email]>:
