FGS.LtsEventMap

Element Description

The FGS.LtsEventMap element is used to create Log Tank Service (LTS) trigger resources for FunctionGraph. LTS triggers depend on the LTS service. To create LTS triggers, you need to enable the LTS service. Based on LTS events, LTS triggers can trigger function execution.
