504 gateway timeout error NodeJs

Question

I have an application which is hosted in DC/OS instance, The application query the snowflake database and get the result. I am using snowflake sdk to to query the snowflake data base, we are also streaming the result we are getting from snowflake.

 var statement = connection.execute({
          sqlText: sql,
          complete: function (err, stmt, rows) {
    var stream = stmt.streamRows();
                  callback(err, stream, response);
}}

But if querying is large and the processing of query takes time in snowflake , I get 504 gateway timeout error at my client.although the node service is still running , but suppose I am hitting DC/OS from browser/postman I will get 504 timeout error here but snowflake returns result to my node service. What is the right strategy to avoid it ? this is the error which I am getting at my client from the server though my node service still maintains connection with snowflake and get the result from snowflake.

@raccoon we started processing the query in background, we process the request and store the result in Cassandra and later get it. — user3649361, Aug 10 '18 at 08:35

Can you check what your statement timeout is set to?

Can you try out the following :

https://docs.snowflake.com/en/sql-reference/sql/alter-user.html

# set timeout to 15 minutes
alter user USERNAME set STATEMENT_TIMEOUT_IN_SECONDS = 900;

https://docs.snowflake.com/en/sql-reference/sql/alter-session.html

STATEMENT_TIMEOUT_IN_SECONDS =

Examples Set the lock timeout for statements executed in the session to 1 hour (3600 seconds):

alter session set STATEMENT_TIMEOUT_IN_SECONDS = 3600;

Set the lock timeout for statements executed in the session back to the default:

alter session unset STATEMENT_TIMEOUT_IN_SECONDS;
