Token bucket

type.TokenBucket

[type.TokenBucket proto]

Configures a token bucket, typically used for rate limiting.

{
  "max_tokens": "...",
  "tokens_per_fill": "{...}",
  "fill_interval": "{...}"
}

max_tokens

(uint32) The maximum tokens that the bucket can hold. This is also the number of tokens that the bucket initially contains.

tokens_per_fill

(UInt32Value) The number of tokens added to the bucket during each fill interval. If not specified, defaults to a single token.

fill_interval

(Duration, REQUIRED) The fill interval that tokens are added to the bucket. During each fill interval tokens_per_fill are added to the bucket. The bucket will never contain more than max_tokens tokens.
