Hi Dipanjan, Here the ’standalone’ is short for ’standalone cluster mode’, which means you can setup a standalone Flink cluster and submit your SQL queries (via SQL client) to the cluster.
As far as I know, the current SQL client can only connect to a Flink cluster deployed in standalone mode. Hope that helps.
