Cloud Data Governance and Catalog APIs are throttled by default to provide optimal use of API resources.
By default, every API provides the following response headers for rate limits based on the number of API calls for each API key:
Response Header
Description
ratelimit-limit
Returns the number of requests allowed for the client in the time window. By default, you can make 120 API calls per minute and 10000 calls per day.
ratelimit-remaining
Returns the number of remaining requests in the current window.
ratelimit-reset
Returns the time remaining in the current window within which you can make the remaining API calls. This time is specified in seconds.
For example, if the value of ratelimit-remaining is 118 calls and ratelimit-reset is 28 seconds, then it means that you can make 118 API calls in the next 28 seconds. If the ratelimit-remaining is 0, wait for the ratelimit-reset value to reset before attempting the API request again.
If you send too many requests in a given amount of time and has reached the API rate limit, the response header HTTP 429: Too Many Requests is returned.
