Is it possible to cache whitelist ?

[WentingWu666666]

We got read timeout exception as follows. May I know if it's possible to implement a cache for whitelist so that ecaudit doesn't need to query whitelist for each operation ?

Sorry for the late replay.

The whitelist is already cached in ecAudit, this exception was thrown then the cache was updated.
