Update Frequencies
Intro
Each NBA API endpoint updates at a variable frequency, in terms of both its cache and its data.
For example, a Game endpoint may have a 2-second cache during a live game and a 120-second cache outside of a live game. Alternatively, a Standings endpoint may have a 120-second cache, but the data within will only update when games conclude. And during the offseason data will not update at all.
Given your limited amount of API requests and QPS, these frequencies should be understood and factored into your pull rate.
Use this section to help determine the best pull frequency for your needs.
Time-to-Live (TTL) and Data Updates
Understanding the distinction between TTL and data updates is crucial for designing an efficient and reliable NBA API solution. TTL is focused on the validity of cached data to optimize performance, whereas data updates are concerned with the actual data within the API.
Time-to-Live (TTL)
Time-to-Live (TTL) is a mechanism used to define the lifespan of data in a cache or network. It specifies the duration for which the data remains valid and can be reused. Once the TTL expires, the data could be stale and must be re-fetched.
You can find the TTL for each RESTful feed in the response header of a request under Cache-Control. A response of public, must-revalidate, max-age=300 signifies a time-to-live of 300 seconds.
Data Updates
Data Updates refer to the changes made to the underlying data that the API provides access to. This can occur through various operations such as creating, updating, or deleting our sports data.
Data updates are critical to ensuring that the API delivers the most current and accurate information. Data entry workflows and processes specific to NBA data will affect your suggested request frequency.
Additional Frequency Resources
NBA API responses also provide expires and etag headers. Toggle between the two header samples below to get an idea of how each functions.
Expires
Use the expires header date to determine a specific time to re-fetch data. In cases, it may be more convenient than computing the date of the content alongside the TTL.
Etags
Use the etags header to check if the content has changed between requests.
