Julian Hyde commented on CALCITE-640:
-------------------------------------
Can you add connect-string parameters (in enum BuiltInConnectionProperty) for
connectionTimeout and statementTimeout with sensible defaults. Make them
strings so that people can write "10s" or "10000ms" if they want, and they mean
the same as "10".
In their doc, specify their time unit and note the fact that they are for
inactivity (on the part of both the server and client). If a connection has a
timeout of 1h and creates or closes a statement every 59m it will never time
out.
