------------------------------------

             Summary: ODBC driver should handle ungraceful tcp disconnects
                 Key: IGNITE-6835
                 URL: https://issues.apache.org/jira/browse/IGNITE-6835
             Project: Ignite
          Issue Type: Bug
      Security Level: Public (Viewable by anyone)
          Components: odbc
    Affects Versions: 2.1
            Reporter: Alexey Popov


It is found that ungraceful TCP disconnect makes ODBC driver stuck at socket recv().
Ungraceful TCP disconnect could be caused:
1. Network failure (or new firewall rules)
2. Remote party shutdown (Half Closed Connection)

So, the proposal is:
setup socket  options: 
1) SO_KEEPALIVE enabled
2) TCP_KEEPIDLE to 60 sec. It is 2 hour by default
3) TCP_KEEPINTVL to 5 (?) sec. It is 1 sec at Win and 75 sec at Linux by default.
4) send/receive buffers to some greater value (8k by default)
