ResumeSession - Function Compute - Alibaba Cloud Documentation Center

Operation description

Resumes a session that is in the Paused state. The system quickly resumes the session in a new execution environment using its previously persisted state. After a successful resume, the session status changes to Active, and the session begins accepting function invocation requests and routing them to the resumed instance. Use this operation with custom image functions that use HEADER_FIELD or GENERATED_COOKIE session affinity and session isolation.
