It looks like they have a MongoDB query parser in the package, so the most likely thing seems to me to be that the query is executed against whatever data already exists on the client (in cache) and then the object returned is backfilled with additional data when it comes back from the server. Because of the "everything realtime" principle, it seems like it would be conceptually simple to just update the dataset when the query finished executing and treat it the same on the application side as new records. I haven't gotten deep enough into the code to see how it works, but that's my gut. > -- > Job Board: http://jobs.nodejs.org/ > Posting guidelines: > https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines > You received this message because you are subscribed to the Google > Groups "nodejs" group. > To post to this group, send email to [email protected] > To unsubscribe from this group, send email to > [email protected] > For more options, visit this group at > http://groups.google.com/group/nodejs?hl=en?hl=en > -- chrisrhoden -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
