Tailable cursor closing when reaching end of collection

Question

I am attempting to stream some data from a MongoDB capped collection as follows:

var query = {};
var options = {tailable: true, awaitdata: true, numberOfRetries: Number.MAX_VALUE};

var stream = myColl.find(query, options).stream();

stream.on('data', function(doc){
    console.log(doc);
}).on('error', function (error){
    console.log(error);
}).on('close', function () {
    console.log('closed');
});

This prints the documents as expected but upon reaching the end of the collection the stream closes. Is it possible to prevent this from happening? I am looking to have the program print the data as it arrives in the collection, waiting at the end of the collection indefinitely for more data.

Answer 1

解决了这个问题。结果我的问题是我没有正确格式化我的选项。

myColl.find().tailable(true, { awaitdata: true ,numberOfRetries:  Number.MAX_VALUE}).stream();

是正确的，并按预期工作。
