dashdb

问题 I have a node-red flow in bluemix that uses dash-db nodes also. So each time some dash db maintenance or some other reason, this db connection gets lost and all writes fail. When i redeploy, everything is fine again. Bluemix shows only logs of last few hours hence I am finding it very difficult to debug. Meanwhile i was thinking of doing an automatic redeploy after i detect this issue to avoid losing writes. Can this be done using GET /flows followed by POST /flows in the same node-red app
