Datamapper & connection pool logic

[kapso]

So I am trying to use datamapper inside my Rails 3.2.8 app.

I have a config/initializers/dm.rb where I load the database.yml

hash = YAML.load(File.new("database.yml"))
DataMapper.setup(:default, hash[Rails.env])

I have a pool property set in the database.yml file, but I noticed that datamapper does not use that. It has this magic number 8 which it uses, where is this number coming from? And how can I configure pool settings for datamapper.

Can you post the database.yml with credentials stripped?

was this ever figured out? How do you set the datamapper pool size in the settings?

All of that stuff gets set down in DataObjects, and i can't remember
exactly how to set it off hand. There should be a setting you can control
through the database setup, but I don't recall off hand (and i'm totally
swamped, otherwise i would lend a hand). Hopefully knowing where to look
can give you a leg up on digging into the details.

I found the code, but is the pool size and number of threads passed in via the database.yml file? IE is there pool: 100 setting?

There is no mention of pool in dm-rails either: https://github.com/datamapper/dm-rails

The connection pooling appears to be done on a per-connection/adapter basis: https://github.com/datamapper/do/search?utf8=%E2%9C%93&q=pool_size

@nmccready To answer your question, it appears that the answer is no. I've opened an issue in DO to add the basic support for something like this. But I don't know if/when it will be done.
