Rate limiting

The rate limiting algorithm works as follows:

• each function type can either count the # of calls it gets or the # of results returned rate_calls=False
• each function type can have a weight rate_weight=1
• each request is identified by its IP or by one value of its context if set context_identifier
• a single query can score a maximum of query_limit
• multiple queries can sum up to window_limit in a window_sec window
• when there is multiple typegates (N), you can improve performance by avoiding score synchronizing while the typegate has not reached local_excess: the real maximum score is thus window_limit + min(local_excess, query_limit) * N

Playing with the above should allow you to quickly hit the limits.
