Hi,

Many people have reported that queries are broken due to mystery time out, while the server's load is not heavy, even with only 1 client. But there is no clear explanation yet. Unfortunately, I hit the same bug and have to dig it myself.

After digging into the libcouchbase source code, I found that there is a field called views_timeout in the lcb instance set in lcb_create():

obj->views_timeout = LCB_DEFAULT_VIEW_TIMEOUT; // 75000000 -> 75 sec

And lcb_http_request_connect() sets it as the connection timeout:

conn->timeout.usec = req->instance->views_timeout;

Thus, all queries longer than 75 sec will be interrupt by the timer.

We can use lcb_set_view_timeout() to set a longer views_timeout. Unfortunately, there is no doc in couchbase.com to describe this:

https://www.google.com/search?q=lcb_set_view_timeout+site%3Acouchbase.com

And there is no such an interface exposed by the python client library.

I suggest that we need to add this interface to python client libraries, and add a doc into related documents.

thanks,

Lenx
