Ephemeral Storage
Ephemeral storage is temporary storage that is not intended to persist beyond the lifetime of the compute instance or container session.
Many agent tasks (like compiling code or running ephemeral tests) need file-system access, but that data is irrelevant after the task completes. Ephemeral storage provides high-performance, temporary scratch space. It is intentionally cleared after the task finishes to keep the environment clean and prevent cross-task data leakage.
