Error on streaming huge recordset

See original GitHub issue

Hi @patriksimek please consider following issue.

"mssql": "^3.3.0",

  mssql: Object.assign({}, {
        stream: true,
        options: {encrypt: false},
        debug: true,
        requestTimeout: 50000,
        pool: {
            max: 10,
            min: 0,
            idleTimeoutMillis: 100000,
        },
    }),

Hi, I have error on while streaming 1000.000. It begin streaming normally but after interruption can’t proceed.

Code looks like following:

 const requestGenerator = MssqlAdaptor.Factory(mssql);
            requestGenerator.then((adaptor) => {
                let request = adaptor.request;


                request.on('error', function (err){
                    console.log('Request error');
                    console.log(err);

                });
                request.on('row', function (data){
                    console.log('Next data: ' + data);
                    elasticAdaptor.addRawData([data]);

                });
                request.on('done', function (){
                    elasticAdaptor.replaceOldIndex().then(function (err, result) {
                        done(null, "Finished");

                    });
                });

                adaptor.executeRequest(query);
            });
