Replace deprecated mongodb $pushAll operator with $push + $each

According to MongoDB documentation $pushAll has been deprecated since version 2.4. However, it remains the operator Array#push translates into.

On the assumption that is not a breaking change, I think it would be a convenient fix, since some implementation may not rely on $pushAll. In fact, for what it is worth, Azure’s own MongoDB implementation does not support $pushAll operator AFAIK .

This may mitigate the impact of Array.push relying on $pushAll. I tried it myself and seems to work.

myArray.push(myObject); //breaks on DocumentDB with Mongo API because of $pushAll

instead use

myArray = myArray.concat([myObject]); //this uses $set so no problems

@vkarpov15 Supporting DocumentDB with Mongo Protocol (so not DocumentDB as it is) would be fantastic, even though I can understand that project priorities are on Mongo. Sadly Microsoft seem to have implemented just a fair subset of the latest Mongo API (3.x), so deprecated stuff that comes from 2.x may not work.

In 4.6.4 you’ll be able to use the usePushEach option in schemas: new Schema({ arr: [String] }, { usePushEach: true });
