voyage in singleton mode

Hello all, I'm developing a tepot+voyage(mongodb) web app and I have one doubt, is voyage thread safe? or do I have to take care about using a Mutex because multiple teapot instances can call it.

Thank you all!

Re: voyage in singleton mode

You should not have to worry. The two possible culprits are the VOCache which should be thread safe done by a semaphore. The other one is the connection to the database. Here the connection pool removes that problem.

Hope that answers your question. I use it just as it is in a concurrent environment.

I am very interested in getting started with MongoDB. I’ve been using STON for full object model read/writes, but I’d like to take the next step into a more sustainable path (as my object models grow larger with time).

I’m using Pharo v9 on MacOS. Where should I start? Voyage? Any pointers/tips would be much appreciated!

Thanks,

Russ

Re: voyage in singleton mode

hi,

you can start by voyage which is an Object-Document mapper or directly with the mongo driver if you do not want to use it :)

in any case, installing voyage will install also the driver and you can start there to see how it works ;)
