As of now there is a very small amount of code here. I had three projects using the Rethinker class, and had enough code churn inside the class that it became too painful to keep the three copies in sync. Thus, a library shared among them.

Three main purposes:

round-robin connections among database servers
make sure connections close at proper time
retry retry-able queries on failure

Not really a connection pool, because it doesn't keep any connections open, but it does take care of connection management.

Service Registry

Now also has a ServiceRegistry class, a lightweight solution for service discovery for distributed services. Maintains service info and status in a rethinkdb table called "services".

Usage

import rethinkstuff
r = rethinkstuff.Rethinker(['db0.foo.com', 'db0.foo.com:38015', 'db1.foo.com'], 'my_db')
r.table('my_table').insert({'foo':'bar','baz':2}).run()
for result in r.table('my_table'):
    print("result={}".format(result))
