Receive events from tarantool

[00christian00]

Hi,
Thanks for your work!
Is there any way to send an event from tarantool to node js?
In the example the request is always initiated from node js but this limits a lot the interaction the 2 tools can have.

Hi.
This driver use iproto and this protocol work only in way like request - response.

You can send http query from tarantool by lua to nodeJS server and handle it.

What's your purpose? If something like a tasks you can use https://github.com/tarantool/queue and do polling after some time interval. (I use this way in my project).

Hi,
I am developing a f2p game and just recently hit a wall with my current db , couchbase, for the leaderboard for whose doesn't seem to be suited.
I just found out Tarantool and was fascinated by the fact that you can actually interact with the db at low level.
Some possible scenarios where this could be useful would be:
-Replication. I could setup servers in two remote location and sync them with master-master replication.
Then I would setup a trigger and would like to be able to notify node js of it.
By the way can you get the tuple on trigger? The docs doesn't mention it.
-Message system to talk between all server in the cluster, both node and tarantool.

Of course there are many workaround possible, but it would be nice if it would be possible natively.
If the protocol doesn't allow it, I'll have to ask the devs then.

No.

Protocol doesn't work in pub/sub mode in current version. You can do a polling only and on tarantool side send an answer on trigger.

Hi, any plan to implement tarantool queue in Node.js just like go-tarantool and python do? Thanks
