Client-Side timeout couchbase node js

Question

I am trying to send few hundreds (448 to be exact) of small documents (20 KB each) to my Couchbase server which has been setup using couchbase AMI . I used the following code in Node.JS

var couchbase = require('couchbase');
var cluster = new couchbase.Cluster('couchbase://54.xx.xxx.xxx:8091');
var bucket = cluster.openBucket('myBucket', 'password', function(err) {
    if(err){
        console.log("Can't open bucket");
        throw err;
    }
    else {
        console.log("Successfully opened bucket");
    }
});
function addToDatabase(data) {
    var key = some key;
    bucket.upsert(key, data, function(err, result) {
        if (err) {
            return console.log(err);
        }
        console.log(result);

    });
}

It sends about 50 documents successfully and then gives me a timeout error:

{ [CouchbaseError: Client-Side timeout exceeded for operation. Inspect network conditions or increase the timeout]  message: 'Client-Side timeout exceeded for operation. Inspect network conditions or increase the timeout',  code: 23 }

I am using the latest version(2.1.2) of couchnode .

I increased the timeout on bucket connection (bucket.operationTimeout=500*1000). After this change it sends all the documents successfully, but it is not a solution because I would not know what is the best value for operationTimeout. Any suggestion would be appreciated.

Answer 1

It sounds to me like you are resource constrained on your client, like file descriptors (something MacOS is known to have not enough of), RAM, sockets, something. I bet if you were to spin up another AWS instance, you'd see this same code load your data in no time and get the access times you are looking for.

I have the same issue with CouchBase on AWS. I solved it by opening the following ports to anyone:

22 tcp 0.0.0.0/0
4369 tcp 0.0.0.0/0
4984 tcp 0.0.0.0/0
8080 tcp 0.0.0.0/0
8088 tcp 0.0.0.0/0
8091 tcp 0.0.0.0/0
8092 tcp 0.0.0.0/0
11209 tcp 0.0.0.0/0
11210 tcp 0.0.0.0/0
11211 tcp 0.0.0.0/0
11214 tcp 0.0.0.0/0
