Mongo.cr and the event loop #29

Open ursuscamp opened 7 years ago

ursuscamp commented 7 years ago

Does mongo.cr use the asynchronous event loop provided by Crystal, or will it block?

datanoise commented 7 years ago

mongo.cr is using mongoc driver which by default is using libc IO. So it will block the process. As an experiment I implemented src/mongo/stream.cr to delegate all IO operations to crystal event loop. Please try it and let me know if it helps.

Looking through the code, it seems all it needs to set it up is to call setup_stream on the Mongo::Client instance. Is that correct?

datanoise commented 7 years ago

That's correct.
