Hi team ,

I am running a N1SQL query and when a data node is unavailable or abruptly crashed , how much time my query node will wait to get data before the data node failover happens .

Thanks

Query timeout is controlled by timeout request parameter. Most SDKs sets 75sec.
Query service uses this also set this value to data node socket. In the absence of this we use 2.5sec for each key value fetch (One can controlled via kvtimeout Configure Queries | Couchbase Docs)
If data node down we wait until KV switch replica and inform not my vbucket and we will retry.
