Usage instructions
Sets the eviction duration for the OAuth2 cache. Credentials that have not been used for more than the eviction duration will be cleaned up during regular refresh tasks. You can increase the evict_time when catalog access is very frequent to avoid frequent re-obtaining. When memory resources are tight, you can decrease the evict_time to reduce resource consumption. Supported units include microseconds (us), milliseconds (ms), seconds (s), minutes (m), hours (h), and days (d). The default is seconds.
Usage examples
Set the eviction duration for the REST Catalog OAuth2 credential cache to 30 minutes.
