▶Access Control Block

1) Rate Limit

• Control the request limits of the API.
• Call API as much as count for period (second).
• After the number of calls is exceeded, a LimitExceedException occurs.

2) Throttle

• It controls calls to occur at regular intervals even if API requests are made several times.

• null : Manage token state for each API
• string : Create and manage a separate key with the given string (bizUnit unit) | string | null | | expiration | Duration of key creation (managed by Redis) If the key expires, the token creation state is initialized. | int | - | | blocking | Set whether to retry if no token exists (bool type)
• null, false : 429 Too many request return without waiting
• true : wait for the token to be created and try again | boolean | null |
